Objective-C Question

UIButton inside a view that has a UITapGestureRecognizer

I have view with a

. So when I tap on the view another view appears above this view. This new view has three buttons. When I now press on one of these buttons I don't get the buttons action, I only get the tap gesture action. So I'm not able to use these buttons anymore. What can I do to get the events through to these buttons? The weird thing is that the buttons still get highlighted.

I can't just remove the UITapGestureRecognizer after I received it's tap. Because with it the new view can also be removed. Means I want a behavior like the fullscreen vide controls.


You can set your controller or view (whichever creates the gesture recognizer) as the delegate of the UITapGestureRecognizer. Then in the delegate you can implement -gestureRecognizer:shouldReceiveTouch:. In your implementation you can test if the touch belongs to your new subview, and if it does, instruct the gesture recognizer to ignore it. Something like the following:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    // test if our control subview is on-screen
    if (self.controlSubview.superview != nil) {
        if ([touch.view isDescendantOfView:self.controlSubview]) {
            // we touched our control surface
            return NO; // ignore the touch
    return YES; // handle the touch
