UIButton touch event falls through to underlying view

Question

I have created a small UIView which contains two UIButtons. The view responds to UITapGesture events. The Buttons are supposed to respond to TouchUpInside, however when I tap the buttons the responder is the underlying view and the tap gesture selector is triggered. Looking for advice or suggestions.

Answer 1

You can modify the method that responds to the tap gesture in the orange view:

-(void) handleTapFrom:(UITapGestureRecognizer*) recognizer {
    CGPoint location = [recognizer locationInView:orangeView];
    UIView *hitView = [orangeView hitTest:location withEvent:nil];

    if ([hitView isKindOfClass:[UIButton class]]) {
        return;
    }

    //code that handle orange view tap
    ...
}

This way if you touch a UIButton, the tap will be ignored by the underlying view.

Answer 2

The right answer (which prevents the tabrecognizer from highjacking any taps and doesn't need you to implement a delegate etc) is found here. I got a lead to this answer via this post.

In short use:

tapRecognizer.cancelsTouchesInView = NO;
