Answer 1

There are better ways to go about this, try adding a UITapGestureRecognizer to the UIImageView. That way you won't need to use the touchesEnded function and check all the touches.

Also, make sure you have set userInteractionEnabled on your UIImageView to YES and that your UIImageView is not underneath any other subviews that may be preventing the tap being detected.

EXAMPLE

- (void)viewDidLoad
{
  [super viewDidLoad];

  UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(imageViewTapped:)];
  [self.myImageView addGestureRecognizer:tapGestureRecognizer];

  self.myImageView.userInteractionEnabled = YES;
  [self.view bringSubviewToFront: self.myImageView];
}

- (void)imageViewTapped:(UITapGestureRecognizer *)tapGestureRecognizer
{
    //Do what you need to do.
}
