tablo görünümünde delege böyle bir şey yapın
ObjC:
- (void)scrollViewDidScroll:(UIScrollView *)aScrollView {
CGPoint offset = aScrollView.contentOffset;
CGRect bounds = aScrollView.bounds;
CGSize size = aScrollView.contentSize;
UIEdgeInsets inset = aScrollView.contentInset;
float y = offset.y + bounds.size.height - inset.bottom;
float h = size.height;
// NSLog(@"offset: %f", offset.y);
// NSLog(@"content.height: %f", size.height);
// NSLog(@"bounds.height: %f", bounds.size.height);
// NSLog(@"inset.top: %f", inset.top);
// NSLog(@"inset.bottom: %f", inset.bottom);
// NSLog(@"pos: %f of %f", y, h);
float reload_distance = 10;
if(y > h + reload_distance) {
NSLog(@"load more rows");
}
}
Swift:
func scrollViewDidScroll(_ scrollView: UIScrollView) {
let offset = scrollView.contentOffset
let bounds = scrollView.bounds
let size = scrollView.contentSize
let inset = scrollView.contentInset
let y = offset.y + bounds.size.height - inset.bottom
let h = size.height
let reload_distance:CGFloat = 10.0
if y > (h + reload_distance) {
print("load more rows")
}
}
