UIImageView中的UISwipeGestureRecognizer

[英]UISwipeGestureRecognizer in UIImageView

I want to put two swipe gesture recognizers in a UIImageView but gestures aren't recognized. 我想在UIImageView中放置两个滑动手势识别器,但无法识别手势。 Only recognizes the tap gesture. 仅识别轻击手势。

This is my code: 这是我的代码:

 - (void)viewDidLoad {

  //Acciones
     img = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[urls
                                                                                       objectAtIndex:index]]]];

    UIImage *img2;

    if (img.size.height > img.size.width) {
         img2 = [[UIImage alloc] initWithCGImage: img.CGImage scale:1.0 orientation: UIImageOrientationUp];
     }else{
         img2 = [[UIImage alloc] initWithCGImage: img.CGImage scale:1.0 orientation: UIImageOrientationRight];
    }

     imageSelected.image = img2;
     [imageSelected setUserInteractionEnabled:YES];
     imageSelected.contentMode = UIViewContentModeScaleAspectFit;
     imageSelected.backgroundColor= [UIColor whiteColor];

     UITapGestureRecognizer *singleTap =  [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(exitAction:)];
     [singleTap setNumberOfTapsRequired:1];
     [imageSelected addGestureRecognizer:singleTap]; 

     UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwipe:)];
     swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;
     [imageSelected addGestureRecognizer:swipeLeft];

     UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self  action:@selector(leftSwipe:)];
     swipeRight.direction = UISwipeGestureRecognizerDirectionRight;
     [imageSelected addGestureRecognizer:swipeRight];

 }

Swipe function: 滑动功能:

 -(IBAction)leftSwipe:(id)sender{ NSLog(@"Left Swipe");    }

Thank you for advance. 谢谢您的提前。

The solution for me was: 我的解决方案是:

Set a delegate for your gestures and return YES from gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer: 为您的手势设置一个委托,并从gestureRecognizer中返回YES:shouldRecognizeWithWithGestureRecognizer:
