UITextField Klavye türünü programlı olarak değiştirme

Bir uitextfield'ın klavye türünü programlı olarak değiştirmek mümkün müdür, böylece böyle bir şey mümkün olur:

if(user is prompted for numeric input only)
    [textField setKeyboardType: @"Number Pad"];

if(user is prompted for alphanumeric input)
    [textField setKeyboardType: @"Default"];

Şunun için bir keyboardTypemülk vardır UITextField:

typedef enum {
    UIKeyboardTypeDefault,                // Default type for the current input method.
    UIKeyboardTypeASCIICapable,           // Displays a keyboard which can enter ASCII characters, non-ASCII keyboards remain active
    UIKeyboardTypeNumbersAndPunctuation,  // Numbers and assorted punctuation.
    UIKeyboardTypeURL,                    // A type optimized for URL entry (shows . / .com prominently).
    UIKeyboardTypeNumberPad,              // A number pad (0-9). Suitable for PIN entry.
    UIKeyboardTypePhonePad,               // A phone pad (1-9, *, 0, #, with letters under the numbers).
    UIKeyboardTypeNamePhonePad,           // A type optimized for entering a person's name or phone number.
    UIKeyboardTypeEmailAddress,           // A type optimized for multiple email address entry (shows space @ . prominently).
    UIKeyboardTypeDecimalPad,             // A number pad including a decimal point
    UIKeyboardTypeTwitter,                // Optimized for entering Twitter messages (shows # and @)
    UIKeyboardTypeWebSearch,              // Optimized for URL and search term entry (shows space and .)

    UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable, // Deprecated

} UIKeyboardType;

Kodunuz okunmalı

if(user is prompted for numeric input only)
    [textField setKeyboardType:UIKeyboardTypeNumberPad];

if(user is prompted for alphanumeric input)
    [textField setKeyboardType:UIKeyboardTypeDefault];

Şu anda odaklanmış bir alanın klavye türünü hemen güncellemesini istiyorsanız , fazladan bir adım olduğunu belirtmek gerekir :

// textField is set to a UIKeyboardType other than UIKeyboardTypeEmailAddress

[textField setKeyboardType:UIKeyboardTypeEmailAddress];
[textField reloadInputViews];

Çağrı reloadInputViewsyapılmazsa, seçilen alan ( ilk cevaplayıcı ) kaybedip odaklanana kadar klavye değişmez .

UIKeyboardTypeDeğerlerin tam bir listesini burada bulabilirsiniz veya:

typedef enum : NSInteger {
    UIKeyboardTypeDefault,
    UIKeyboardTypeASCIICapable,
    UIKeyboardTypeNumbersAndPunctuation,
    UIKeyboardTypeURL,
    UIKeyboardTypeNumberPad,
    UIKeyboardTypePhonePad,
    UIKeyboardTypeNamePhonePad,
    UIKeyboardTypeEmailAddress,
    UIKeyboardTypeDecimalPad,
    UIKeyboardTypeTwitter,
    UIKeyboardTypeWebSearch,
    UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable
} UIKeyboardType;

Evet şunları yapabilirsiniz:

[textField setKeyboardType:UIKeyboardTypeNumberPad];

    textFieldView.keyboardType = UIKeyboardType.PhonePad

Bu hızlı. Ayrıca bunun düzgün çalışması için,textFieldView.delegate = self

metin alanının alfa sayısal kabul etmesini sağlamak için yalnızca bu özelliği ayarlayın

textField.keyboardType = UIKeyboardTypeNamePhonePad;

_textField .keyboardType = UIKeyboardTypeAlphabet;
_textField .keyboardType = UIKeyboardTypeASCIICapable;
_textField .keyboardType = UIKeyboardTypeDecimalPad;
_textField .keyboardType = UIKeyboardTypeDefault;
_textField .keyboardType = UIKeyboardTypeEmailAddress;
_textField .keyboardType = UIKeyboardTypeNamePhonePad;
_textField .keyboardType = UIKeyboardTypeNumberPad;
_textField .keyboardType = UIKeyboardTypeNumbersAndPunctuation;
_textField .keyboardType = UIKeyboardTypePhonePad;
_textField .keyboardType = UIKeyboardTypeTwitter;
_textField .keyboardType = UIKeyboardTypeURL;
_textField .keyboardType = UIKeyboardTypeWebSearch;

Bir koşul karşılandığında klavye türünüzü değiştirmeye çalışıyorsanız, bunu izleyin. Örneğin: Metin alanının sayısı 4 veya 5 olduğunda klavye türünü Varsayılan yerine Sayısal Tuş Takımı olarak değiştirmek istiyorsak , bunu yapın:

textField.addTarget(self, action: #selector(handleTextChange), for: .editingChanged)

@objc func handleTextChange(_ textChange: UITextField) {
 if textField.text?.count == 4 || textField.text?.count == 5 {
   textField.keyboardType = .numberPad
   textField.reloadInputViews() // need to reload the input view for this to work
 } else {
   textField.keyboardType = .default
   textField.reloadInputViews()
 }

Bunun için bir özellik var keyboardType. Ne yapmak isteyeceksiniz Eğer dizeleri sahip olduğu yerini ise @"Number Padve @"Defaultile UIKeyboardTypeNumberPadve UIKeyboardTypeDefault.

Yeni kodunuz şöyle görünmelidir:

if(user is prompted for numeric input only)
    [textField setKeyboardType:UIKeyboardTypeNumberPad];

else if(user is prompted for alphanumeric input)
    [textField setKeyboardType:UIKeyboardTypeDefault];

İyi şanslar!

UIDatePickergirdi olarak kullanmak isteyenler için :

UIDatePicker *timePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 250, 0, 0)];
[timePicker addTarget:self action:@selector(pickerChanged:)
     forControlEvents:UIControlEventValueChanged];
[_textField setInputView:timePicker];

// pickerChanged:
- (void)pickerChanged:(id)sender {
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"d/M/Y"];
    _textField.text = [formatter stringFromDate:[sender date]];
}

Bu UIKeyboardTypesSwift 3:

public enum UIKeyboardType : Int {

    case `default` // Default type for the current input method.
    case asciiCapable // Displays a keyboard which can enter ASCII characters
    case numbersAndPunctuation // Numbers and assorted punctuation.
    case URL // A type optimized for URL entry (shows . / .com prominently).
    case numberPad // A number pad with locale-appropriate digits (0-9, ۰-۹, ०-९, etc.). Suitable for PIN entry.
    case phonePad // A phone pad (1-9, *, 0, #, with letters under the numbers).
    case namePhonePad // A type optimized for entering a person's name or phone number.
    case emailAddress // A type optimized for multiple email address entry (shows space @ . prominently).

    @available(iOS 4.1, *)
    case decimalPad // A number pad with a decimal point.

    @available(iOS 5.0, *)
    case twitter // A type optimized for twitter text entry (easy access to @ #)

    @available(iOS 7.0, *)
    case webSearch // A default keyboard type with URL-oriented addition (shows space . prominently).

    @available(iOS 10.0, *)
    case asciiCapableNumberPad // A number pad (0-9) that will always be ASCII digits.


    public static var alphabet: UIKeyboardType { get } // Deprecated
}

Bu, listeden bir klavye türü kullanmak için bir örnektir:

textField.keyboardType = .numberPad
