我想在 UIImageView 中放置两个滑动手势识别器，但无法识别手势。仅识别点击手势。
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];
}
滑动功能:
-(IBAction)leftSwipe:(id)sender{ NSLog(@"Left Swipe"); }
谢谢你的提前。
最佳答案
我的解决方案是:
Set a delegate for your gestures and return YES from gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:
