TapGesture recognizer on multiple UIImageView not working
ios, objective-c, uiimageview, uitapgesturerecognizer
Solution
As borrrden said, when trying to track gesture, each view must have its own gestureRecognizer. For each of your sample_books, you should use
[sample_bookX addGestureRecognizer:[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(myFunction:)]];
instead of trying to add multiple times the same GR
The argument received by myFunction: would then be the proper tapGR and you could get to the tapped imageView by calling sender.view (providing your myFunction signature look like
- (void) myFunction:(UIGestureRecognizer *)sender
Cheers,
Problem
TapGesture recognizer on multiple UIImageView is not working, while it detects last added imageviews gesture.. I have done this, ``` UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(myFunction:)]; tapped.numberOfTapsRequired = 1; tapped.delegate = self; UIImageView *sample_book1= [[UIImageView alloc]initWithFrame:CGRectMake(70, 135, 100,125) ]; sample_book1.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"mathematics.png"]]; sample_book1.userInteractionEnabled = YES; sample_book1.tag = 0; [sample_book1 addGestureRecognizer:tapped]; [self.view addSubview:sample_book1]; UIImageView *sample_book2= [[UIImageView alloc]initWithFrame:CGRectMake(220, 135, 100,125) ]; sample_book2.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"biology.png"]]; sample_book2.userInteractionEnabled = YES; sample_book2.tag = 1; [sample_book2 addGestureRecognizer:tapped]; [self.view addSubview:sample_book2]; UIImageView *sample_book3= [[UIImageView alloc]initWithFrame:CGRectMake(370, 135, 100,125) ]; sample_book3.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"chemistry.png"]]; sample_book3.userInteractionEnabled = YES; sample_book3.tag = 2; [sample_book3 addGestureRecognizer:tapped]; [self.view addSubview:sample_book3]; ``` The tap gesture is not working in sample_book1,sample_book2.... it's only working in sample_book3.. What i'm doing wrong..
