I have view with a UITapGestureRecognizer
. 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
}
