Kullanıcının Swift ile resmi seçmesine nasıl izin verilir?

Question 1

Swift ile ilk iOS uygulamamı (yalnızca iPhone) yazıyorum. Ana uygulama görünümü, kullanıcının fotoğraf galerisinden resmi seçmesine izin vermelidir.

ViewController.swift'in aşağıdaki örnek kodunu buldum :

class ViewController: UIImagePickerController, UINavigationControllerDelegate, UIImagePickerControllerDelegate  {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {

        var imagePickerController = UIImagePickerController()
        imagePickerController.delegate = self
        imagePickerController.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
        imagePickerController.allowsEditing = true
        self.presentViewController(imagePickerController, animated: true, completion: { imageP in

        })
    }


    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!) {
        let selectedImage : UIImage = image
        println(selectedImage)
    }

}

Ancak uygulamayı başlattığımda sadece siyah ekran gösteriliyor. Neyi yanlış yapıyorum? Bulduğum başka bir örnek kod da Objective-C'de, bu bana yardımcı olmuyor.

Question 2

Sadece kullanıcının UIImagePickerController ile görüntü seçmesine izin vermek istiyorsanız bu kodu kullanın:

import UIKit


class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet var imageView: UIImageView!
    @IBOutlet var chooseBuuton: UIButton!
    var imagePicker = UIImagePickerController()

    @IBAction func btnClicked() {

        if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
            print("Button capture")

            imagePicker.delegate = self
            imagePicker.sourceType = .savedPhotosAlbum
            imagePicker.allowsEditing = false

            present(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!){
        self.dismiss(animated: true, completion: { () -> Void in

        })

        imageView.image = image
    }
}

Question 3

@ User3182143 cevabına göre swift 4 için eksiksiz kopyala-yapıştır çalışan görüntü seçiciyi :

import Foundation
import UIKit


class ImagePickerManager: NSObject, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    var picker = UIImagePickerController();
    var alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
    var viewController: UIViewController?
    var pickImageCallback : ((UIImage) -> ())?;
    
    override init(){
        super.init()
        let cameraAction = UIAlertAction(title: "Camera", style: .default){
            UIAlertAction in
            self.openCamera()
        }
        let galleryAction = UIAlertAction(title: "Gallery", style: .default){
            UIAlertAction in
            self.openGallery()
        }
        let cancelAction = UIAlertAction(title: "Cancel", style: .cancel){
            UIAlertAction in
        }

        // Add the actions
        picker.delegate = self
        alert.addAction(cameraAction)
        alert.addAction(galleryAction)
        alert.addAction(cancelAction)
    }

    func pickImage(_ viewController: UIViewController, _ callback: @escaping ((UIImage) -> ())) {
        pickImageCallback = callback;
        self.viewController = viewController;

        alert.popoverPresentationController?.sourceView = self.viewController!.view

        viewController.present(alert, animated: true, completion: nil)
    }
    func openCamera(){
        alert.dismiss(animated: true, completion: nil)
        if(UIImagePickerController .isSourceTypeAvailable(.camera)){
            picker.sourceType = .camera
            self.viewController!.present(picker, animated: true, completion: nil)
        } else {
            let alertWarning = UIAlertView(title:"Warning", message: "You don't have camera", delegate:nil, cancelButtonTitle:"OK", otherButtonTitles:"")
            alertWarning.show()
        }
    }
    func openGallery(){
        alert.dismiss(animated: true, completion: nil)
        picker.sourceType = .photoLibrary
        self.viewController!.present(picker, animated: true, completion: nil)
    }

    
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    }
    //for swift below 4.2
    //func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    //    picker.dismiss(animated: true, completion: nil)
    //    let image = info[UIImagePickerControllerOriginalImage] as! UIImage
    //    pickImageCallback?(image)
    //}
    
    // For Swift 4.2+
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        picker.dismiss(animated: true, completion: nil)
        guard let image = info[.originalImage] as? UIImage else {
            fatalError("Expected a dictionary containing an image, but was provided the following: \(info)")
        }
        pickImageCallback?(image)
    }



    @objc func imagePickerController(_ picker: UIImagePickerController, pickedImage: UIImage?) {
    }

}

Bunu görüntü denetleyicinizden şu şekilde arayın:

    ImagePickerManager().pickImage(self){ image in
        //here is the image
    }

Ayrıca, aşağıdaki anahtarları da eklemeyi unutmayın info.plist:

<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

Question 4

Swift 3 için:

Öncelikle info.plist'e aşağıdaki anahtarı eklemeniz gerekir:

    <key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

View denetleyicinizin aşağıdaki protokollere uyması gerekir: UIImagePickerControllerDelegate, UINavigationControllerDelegate:
```
class ImagePickerViewController:  UIViewController,UIImagePickerControllerDelegate, UINavigationControllerDelegate {}
```

Döndürülen / seçilen görüntüyü bağlamak için kullanacağınız UIImage'ı bildirmeniz gerekir:

@IBOutlet weak var myImageView: UIImageView!
@IBoutlet weak var upLoadImageBtn:UIImage!
let imagePicker = UIImagePickerController()

PickerImage temsilcisini ViewController'ınız olacak şekilde ayarlayın:
```
imagePicker.delegate = self
```

Yükle düğmesi için, eylemi başlatmak ve görüntü seçiciyi görüntülemek için aşağıdaki resme bağlantı oluşturmanız gerekir:

@IBAction func upLoadImageBtnPressed(_ sender: AnyObject) {
    imagePicker.allowsEditing = false
    imagePicker.sourceType = .photoLibrary


    /*
    The sourceType property wants a value of the enum named        UIImagePickerControllerSourceType, which gives 3 options:

    UIImagePickerControllerSourceType.PhotoLibrary
    UIImagePickerControllerSourceType.Camera
    UIImagePickerControllerSourceType.SavedPhotosAlbum

    */
    present(imagePicker, animated: true, completion: nil)

}

Görünüm denetleyicinizin, görüntü seçici temsilcileri için temsilci yöntemlerini uygulaması gerekir:

// MARK: - ImagePicker Delegate

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        myImageView.contentMode = .scaleAspectFit
        myImageView.image = pickedImage
    }


    /*

    Swift Dictionary named “info”.  
    We have to unpack it from there with a key asking for what media information we want.
    We just want the image, so that is what we ask for.  For reference, the available options are:

    UIImagePickerControllerMediaType
    UIImagePickerControllerOriginalImage
    UIImagePickerControllerEditedImage
    UIImagePickerControllerCropRect
    UIImagePickerControllerMediaURL
    UIImagePickerControllerReferenceURL
    UIImagePickerControllerMediaMetadata

    */
    dismiss(animated: true, completion: nil)
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    dismiss(animated: true, completion:nil)
}

Question 5

Görüntüyü seçmeniz için size en anlaşılır kodlamayı vereceğim, buna bakın

func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) 
{
     var alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
     var cameraAction = UIAlertAction(title: "Camera", style: UIAlertActionStyle.Default)
     {
        UIAlertAction in
        self.openCamera()
     }
     var gallaryAction = UIAlertAction(title: "Gallary", style: UIAlertActionStyle.Default)
     {
        UIAlertAction in
        self.openGallary()
     }
     var cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel)
     {
        UIAlertAction in
     }

    // Add the actions
     picker?.delegate = self
     alert.addAction(cameraAction)
     alert.addAction(gallaryAction)
     alert.addAction(cancelAction)
     self.presentViewController(alert, animated: true, completion: nil)
}
func openCamera()
{
    if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera))
    {
        picker!.sourceType = UIImagePickerControllerSourceType.Camera
        self .presentViewController(picker!, animated: true, completion: nil)
    }
    else
    {
        let alertWarning = UIAlertView(title:"Warning", message: "You don't have camera", delegate:nil, cancelButtonTitle:"OK", otherButtonTitles:"")
        alertWarning.show()
    }
}
func openGallary()
{
    picker!.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    self.presentViewController(picker!, animated: true, completion: nil)
}

//PickerView Delegate Methods
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject])
{
    picker .dismissViewControllerAnimated(true, completion: nil)
    imageView.image=info[UIImagePickerControllerOriginalImage] as? UIImage
}
func imagePickerControllerDidCancel(picker: UIImagePickerController)
{
    println("picker cancel.")
}

İyi günler dilerim:-)

Question 6

    @IBAction func chooseProfilePicBtnClicked(sender: AnyObject) {
    let alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
    let cameraAction = UIAlertAction(title: "Camera", style: UIAlertActionStyle.Default)
        {
            UIAlertAction in
            self.openCamera()
    }
    let gallaryAction = UIAlertAction(title: "Gallary", style: UIAlertActionStyle.Default)
        {
            UIAlertAction in
            self.openGallary()
    }
    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel)
        {
            UIAlertAction in
    }

    // Add the actions
    picker.delegate = self
    alert.addAction(cameraAction)
    alert.addAction(gallaryAction)
    alert.addAction(cancelAction)
    self.presentViewController(alert, animated: true, completion: nil)
}
func openCamera(){
    if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)){
        picker.sourceType = UIImagePickerControllerSourceType.Camera
        self .presentViewController(picker, animated: true, completion: nil)
    }else{
        let alert = UIAlertView()
        alert.title = "Warning"
        alert.message = "You don't have camera"
        alert.addButtonWithTitle("OK")
        alert.show()
    }
}
func openGallary(){
    picker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    self.presentViewController(picker, animated: true, completion: nil)
}
//MARK:UIImagePickerControllerDelegate
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]){
    picker .dismissViewControllerAnimated(true, completion: nil)
    imageViewRef.image=info[UIImagePickerControllerOriginalImage] as? UIImage
}
func imagePickerControllerDidCancel(picker: UIImagePickerController){
    print("picker cancel.")
}

Question 7

Swift 5'te bunu yapmalısın

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    @IBOutlet var imageView: UIImageView!
    var imagePicker = UIImagePickerController()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }

    @IBAction func setPicture(_ sender: Any) {
        if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){
            imagePicker.delegate = self
            imagePicker.sourceType = .photoLibrary
            imagePicker.allowsEditing = false

            present(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        picker.dismiss(animated: true, completion: nil)
        if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            imageView.image = image
        }

    }




}

Question 8

XCODE 10.1 / SWIFT 4.2:

Gerekli izinleri ekleyin (diğerleri bahsedildi)
Bu sınıfı görünümünüze ekleyin:

    import UIKit

    import Photos

    import Foundation

class UploadImageViewController: UIViewController, UIImagePickerControllerDelegate , UINavigationControllerDelegate {

        @IBOutlet weak var imgView: UIImageView!

        let imagePicker = UIImagePickerController()

        override func viewDidLoad() {

            super.viewDidLoad()

            checkPermission()

            imagePicker.delegate = self
            imagePicker.allowsEditing = false
            imagePicker.sourceType = .photoLibrary
        }

        @IBAction func btnSetProfileImageClickedCamera(_ sender: UIButton) {
        }

        @IBAction func btnSetProfileImageClickedFromGallery(_ sender: UIButton) {
            self.selectPhotoFromGallery()
        }

        func selectPhotoFromGallery() {
            self.present(imagePicker, animated: true, completion: nil)
        }

        func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

            if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
                    self.imgView.contentMode = .scaleAspectFit
                    self.imgView.image = pickedImage
                }

            dismiss(animated: true, completion: nil)
        }


        func imagePickerControllerDidCancel(_ picker: UIImagePickerController){
            print("cancel is clicked")
        }


        func checkPermission() {
            let photoAuthorizationStatus = PHPhotoLibrary.authorizationStatus()
            switch photoAuthorizationStatus {
            case .authorized:
                print("Access is granted by user")
            case .notDetermined:
                PHPhotoLibrary.requestAuthorization({
                    (newStatus) in
                    print("status is \(newStatus)")
                    if newStatus ==  PHAuthorizationStatus.authorized {
                        /* do stuff here */
                        print("success")
                    }
                })
                print("It is not determined until now")
            case .restricted:
                // same same
                print("User do not have access to photo album.")
            case .denied:
                // same same
                print("User has denied the permission.")
            }
        }
    }

Question 9

Fotoğraf kitaplığı resimlerini hızlı bir şekilde kodlayarak görüntülemek için şunları yapın:

var pkcrviewUI = UIImagePickerController()
        if UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLibrary)
        {
            pkcrviewUI.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
            pkcrviewUI.allowsEditing = true
            pkcrviewUI.delegate = self
            [self .presentViewController(pkcrviewUI, animated: true , completion: nil)]
        }

Question 10

Bunun bir yaşında olduğunu biliyorum, ama işte benim için iyi çalışan oldukça basit bir kod (çoğunlukla bu öğreticiden ):

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

@IBOutlet weak var imageView: UIImageView!

var imagePicker = UIImagePickerController()

override func viewDidLoad() {
    super.viewDidLoad()

    self.imagePicker.delegate = self
}

@IBAction func loadImageButtonTapped(sender: AnyObject) {
    print("hey!")
    self.imagePicker.allowsEditing = false
    self.imagePicker.sourceType = .SavedPhotosAlbum

    self.presentViewController(imagePicker, animated: true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        self.imageView.contentMode = .ScaleAspectFit
        self.imageView.image = pickedImage
    }

    dismissViewControllerAnimated(true, completion: nil)

}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
    self.imagePicker = UIImagePickerController()
    dismissViewControllerAnimated(true, completion: nil)
}

Question 11

Swift 4 için
Bu kod benim için çalışıyor !!

import UIKit


class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet var imageView: UIImageView!
    @IBOutlet var chooseBuuton: UIButton!
    var imagePicker = UIImagePickerController()

    override func viewDidLoad() {
        super.viewDidLoad()
        imagePicker.delegate = self
    }
    @IBAction func btnClicked() {

    if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum) 
    {
        print("Button capture")
        imagePicker.sourceType = .savedPhotosAlbum;
        imagePicker.allowsEditing = false

        self.present(imagePicker, animated: true, completion: nil)
        }
    }

  @objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
    imageView.image = chosenImage

    dismiss(animated: true, completion: nil)
    }
}

Question 12

Elbette yukarıdaki cevaplar ana sorunu çözer.

Fotoğraf albümünü başlatırken Swift 3.0'da bir çökme yaşadım çünkü Info.plist şu işaretlere sahip değildi:

Gizlilik - Fotoğraf Kitaplığı Kullanım Açıklaması -> NSPhotoLibraryUsageDescription
Gizlilik - Kamera Kullanım Açıklaması -> NSCameraUsageDescription

[ ekran görüntüsü [1]

Benzer bir sorunla karşılaşırsanız lütfen bunları ekleyin.

Teşekkürler !

Question 13

işte bunu yapmanın kolay bir yolu:

ancak önce info.plist'e (Gizlilik - Fotoğraf Kitaplığı Kullanım Açıklaması) eklemeniz gerekir ve viewController'ınızda bir düğme ve UIImageView olmalıdır.

daha sonra UIImageView için bir çıkış oluşturun (bu kodda çıkış, myImage olarak adlandırılır) ve düğmenin bir eylemi (kodumda içe aktarmayı çağırdım)

import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

    }
    @IBOutlet weak var myImage: UIImageView!
    @IBAction func importing(_ sender: Any) {
        let Picker = UIImagePickerController()
        Picker.delegate = self
        Picker.sourceType = .photoLibrary
        self.present(Picker, animated: true, completion: nil)
        Picker.allowsEditing = true
        Picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
    }

     func imagePickerController(_ picker: UIImagePickerController,didFinishPickingMediaWithInfo info: [String : Any])
    {
        let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage //1
        myImage.contentMode = .scaleAspectFit //2
        myImage.image = chosenImage //3
        dismiss(animated:true, completion: nil) //4
    }

}

Question 14

Ayrı bir düğmeye sahip olmak istemiyorsanız, işte başka bir yol. İmageView'ın kendisine bir hareket eklendi, burada resme dokunulduğunda iki seçenekli bir uyarı açılır. Galeriden / fotoğraf kitaplığından seçim yapma veya uyarıyı iptal etme seçeneğiniz olacaktır.

import UIKit
import CoreData

class AddDetailsViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

@IBOutlet weak var imageView: UIImageView!

var picker:UIImagePickerController? = UIImagePickerController()

@IBAction func saveButton(sender: AnyObject) {
    let managedContext = (UIApplication.sharedApplication().delegate as? AppDelegate)!.managedObjectContext

    let entity = NSEntityDescription.entityForName("Person", inManagedObjectContext: managedContext)

    let person = Person(entity: entity!, insertIntoManagedObjectContext: managedContext)

    person.image = UIImageJPEGRepresentation(imageView.image!, 1.0) //imageView.image

    do {
         try person.managedObjectContext?.save()
         //people.append(person)
       } catch let error as NSError {
         print("Could not save \(error)")
    }
}

override func viewDidLoad() {
    super.viewDidLoad()
    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(AddDetailsViewController.tapGesture(_:)))
    imageView.addGestureRecognizer(tapGesture)
    imageView.userInteractionEnabled = true

    picker?.delegate = self
    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func tapGesture(gesture: UIGestureRecognizer) {
    let alert:UIAlertController = UIAlertController(title: "Profile Picture Options", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)

    let gallaryAction = UIAlertAction(title: "Open Gallary", style: UIAlertActionStyle.Default) {
        UIAlertAction in self.openGallary()
    }

    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) {
        UIAlertAction in self.cancel()
    }

    alert.addAction(gallaryAction)
    alert.addAction(cancelAction)

    self.presentViewController(alert, animated: true, completion: nil)

}


func openGallary() {
    picker!.allowsEditing = false
    picker!.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    presentViewController(picker!, animated: true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imageView.contentMode = .ScaleAspectFit
        imageView.image = pickedImage
    }

    dismissViewControllerAnimated(true, completion: nil)
}

func cancel(){
    print("Cancel Clicked")
}

}

Soruya daha fazla ekleyerek görüntüleri CoreData'da depolamak için mantık uygulandı.

Question 15

düğmesine tıklayın ve Resim galerisini açın ve görüntüyü imageview swift 3.0'da ayarlayın

üç temsilci UIImagePickerControllerDelegate, UIPopoverControllerDelegate, UINavigationControllerDelegate ekle

var picker:UIImagePickerController?=UIImagePickerController()
@IBOutlet var imgPhoto: UIImageView!

   override func viewDidLoad() {
    super.viewDidLoad()
    picker?.delegate=self
   }

 @IBAction func btnAddPhotoClicked(_ sender: UIButton) {
    openGallary()
   }

func openGallary()
{
    picker!.allowsEditing = false
    picker!.sourceType = UIImagePickerControllerSourceType.photoLibrary
    present(picker!, animated: true, completion: nil)
}

//MARK:- ImagePicker Controller Delegate
//MARK:-

func imagePickerControllerDidCancel(_ picker: 
UIImagePickerController) {
    dismiss(animated: true, completion: nil)
}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let chosenImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imgPhoto.contentMode = .scaleToFill
        imgPhoto.image = chosenImage
    } else{
        print("Something went wrong")
    }

    self.dismiss(animated: true, completion: nil)
}

Question 16

Burada bahsetmek için cevap veriyorum: info[UIImagePickerControllerEditedImage]muhtemelen çoğu durumda kullanmak isteyeceğiniz şeydir.

Bunun dışında buradaki cevaplar kapsamlı.

Question 17

Bunu deneyin, çok kolay .. UIImagePickerControllerDelegate kullanarak bir Görüntüyü resmetmek

    @objc func masterAction(_ sender: UIButton)
    {
        if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
            print("Button capture")

            imagePicker.delegate = self
            imagePicker.sourceType = .savedPhotosAlbum;
            imagePicker.allowsEditing = false

            self.present(imagePicker, animated: true, completion: nil)
        }

        print("hello i'm touch \(sender.tag)")
    }

    func imagePickerControllerDidCancel(_ picker:
        UIImagePickerController) {
        dismiss(animated: true, completion: nil)
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        if let chosenImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
            print("Get Image \(chosenImage)")
            ImageList.insert(chosenImage, at: 0)
            ArrayList.insert("", at: 0)
            Collection_Vw.reloadData()
        } else{
            print("Something went wrong")
        }

        self.dismiss(animated: true, completion: nil)
    }

Question 18

Yalnızca normal görüntüyü seçmek istiyorsanız aşağıdaki kodu kullanabilirsiniz, bu seçilen görüntünün panorama görüntüsü olmadığını kontrol edin.

let picker = UIImagePickerController()

func photoFromLibrary() {

        self.picker.allowsEditing = true
        self.picker.sourceType = .photoLibrary
        //picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!

        self.present(self.picker, animated: true, completion: nil)

}

func shootPhoto() {

            if UIImagePickerController.isSourceTypeAvailable(.camera) {
                self.picker.allowsEditing = true
                self.picker.sourceType = UIImagePickerControllerSourceType.camera
                self.picker.cameraCaptureMode = .photo
                self.picker.modalPresentationStyle = .fullScreen
                self.present(self.picker,animated: true,completion: nil)
            }

}

//Image picker delegate
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    let str = "\(info["UIImagePickerControllerOriginalImage"]!)"

    let s = str.slice(from: "{", to: "}")

    if let arr = s?.components(separatedBy: ","){
        if arr.count >= 2 {
            if Int(arr[0])! > 11000 {
                picker.dismiss(animated:true, completion: nil)
                self.makeToast("Invalid Image!!!")
                return
            }
                     }
        }
    }

    if  let image = info[UIImagePickerControllerOriginalImage] as? UIImage{
        self.UserImageView.image = image
    }
    picker.dismiss(animated:true, completion: nil)
}


func imagePickerControllerDidCancel(_ picker: UIImagePickerController)
{
    picker.dismiss(animated: true, completion: nil)
}

Question 19

Xcode 10, Swift 4.2

Aşağıda uygulamanın biraz optimize edilmiş bir versiyonu bulunmaktadır. Bu Swift 4.2'de ve ben de test ettim.

ViewController için tam kodu burada görebilirsiniz. Storyboard'da tanımlanmış ve bağlanmış bir IBOutlet (imageView) ve IBAction (didTapOnChooseImageButton) tanımlamanız gerektiğini lütfen unutmayın. Bu yardımcı olur umarım.

import UIKit

class ImagePickViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate {

var imagePicker = UIImagePickerController()
@IBOutlet weak var imageView: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
}

@IBAction func didTapOnChooseImageButton(_ sender: Any) {
    let alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertController.Style.actionSheet)
    let cameraAction = UIAlertAction(title: "Camera", style: UIAlertAction.Style.default) {
        UIAlertAction in
        self.openCamera(UIImagePickerController.SourceType.camera)
    }
    let gallaryAction = UIAlertAction(title: "Gallary", style: UIAlertAction.Style.default) {
        UIAlertAction in
        self.openCamera(UIImagePickerController.SourceType.photoLibrary)
    }
    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertAction.Style.cancel) {
        UIAlertAction in
    }

    // Add the actions
    imagePicker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate
    alert.addAction(cameraAction)
    alert.addAction(gallaryAction)
    alert.addAction(cancelAction)
    self.present(alert, animated: true, completion: nil)
}

func openCamera(_ sourceType: UIImagePickerController.SourceType) {
    imagePicker.sourceType = sourceType
    self.present(imagePicker, animated: true, completion: nil)
}

//MARK:UIImagePickerControllerDelegate

func imagePickerController(_ picker: UIImagePickerController,
                                    didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    imageView.image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
    imagePicker.dismiss(animated: true, completion: nil)
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    print("imagePickerController cancel")
}

}

Question 20

Burayı beğenebilirsin

var avatarImageView = UIImageView()
var imagePicker = UIImagePickerController()
        
func takePhotoFromGallery() {
    imagePicker.delegate = self
    imagePicker.sourceType = .savedPhotosAlbum
    imagePicker.allowsEditing = true
    
    present(imagePicker, animated: true)
}

func imagePickerController(_ picker: UIImagePickerController,
                           didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let pickedImage = info[.originalImage] as? UIImage {
        avatarImageView.contentMode = .scaleAspectFill
        avatarImageView.image = pickedImage
    }
    self.dismiss(animated: true)
}

Umarım bu yardımcı olmuştur

Question 21

Swift 3.4.1 için bu kod çalışıyor:

implements                                                             
class AddAdvertisementViewController : UINavigationControllerDelegate, UIImagePickerControllerDelegate, UIActionSheetDelegate  

var imagePicker = UIImagePickerController()                                
var file :UIImage!

 //action sheet tap on image

 func tapOnButton(){   
    let optionMenu = UIAlertController(title: nil, message: "Add Photo", preferredStyle: .actionSheet)

    let galleryAction = UIAlertAction(title: "Gallery", style: .default, handler:{
        (alert: UIAlertAction!) -> Void in
        self.addImageOnTapped()
    })

    let cameraAction = UIAlertAction(title: "Camera", style: .default, handler:{
        (alert: UIAlertAction!) -> Void in
        self.openCameraButton()
    })

    let cancleAction = UIAlertAction(title: "Cancel", style: .cancel, handler:{
        (alert: UIAlertAction!) -> Void in
        print("Cancel")
    })

    optionMenu.addAction(galleryAction)
    optionMenu.addAction(cameraAction)
    optionMenu.addAction(cancleAction)
    self.present(optionMenu, animated: true, completion: nil)
}


func openCameraButton(){
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera)
    {
        imagePicker = UIImagePickerController()
        imagePicker.delegate = self
        imagePicker.sourceType = UIImagePickerControllerSourceType.camera;
        imagePicker.allowsEditing = true
        self.present(imagePicker, animated: true, completion: nil)
    }
}


func addImageOnTapped(){
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary){
        imagePicker.delegate = self
        imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary;
        imagePicker.allowsEditing = true
        self.present(imagePicker, animated: true, completion: nil)
    }
}

//picker pick image and store value imageview
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]){
    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage
    {
            file = image
            imgViewOne.image = image
        imagePicker.dismiss(animated: true, completion: nil);
    }
}

Question 22

@IBAction func ImportImage(_ sender: Any)
{
    let image = UIImagePickerController()
    image.delegate = self

    image.sourceType = UIImagePickerController.SourceType.photoLibrary

    image.allowsEditing = false

    self.present(image, animated: true)
    {
        //After it is complete
    }


}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
    {
        myimage.image = image
    }
    else{
        //
    }
    self.dismiss(animated: true, completion: nil)

    do {
        try context.save()
    } catch {
        print("Could not save. \(error), \(error.localizedDescription)")
    }

}
