For example I have a view where I want two different gestures:
tap to do action A. double tap to do action B.
The problem is with UITapGestureRecognizer I can only set minimum required tap count. The single tap gesture recognizer recognizes a tap before the double tap gesture recognizer recognizes the double tap.
Example:
_tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapGestureRecognized:)];
_tapGestureRecognizer.numberOfTouchesRequired = 1;
_tapGestureRecognizer.numberOfTapsRequired = 1;
[self addGestureRecognizer:_tapGestureRecognizer];
_doubleTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTapGestureRecognized:)];
_doubleTapGestureRecognizer.numberOfTouchesRequired = 1;
_doubleTapGestureRecognizer.numberOfTapsRequired = 2;
[self addGestureRecognizer:_doubleTapGestureRecognizer];
It always recognizes the single tap even if I do double tap very fast. How can I set it up so the tap gesture recognizer waits and sees if the double tap gesture recognizer recognizes?
Here is what I have used in one of my old projects, I hope it helps you out man.
UITapGestureRecognizer *singleTap = [[[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(doSingleTap)] autorelease];
singleTap.numberOfTapsRequired = 1;
[self.view addGestureRecognizer:singleTap];
UITapGestureRecognizer *doubleTap = [[[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(doDoubleTap)] autorelease];
doubleTap.numberOfTapsRequired = 2;
[self.view addGestureRecognizer:doubleTap];
[singleTap requireGestureRecognizerToFail:doubleTap];
