Adding a UIGestureRecognizer taking priority over all other interactions

When I tap on a UIButton, a UIView MyView appear from the bottom a cover a third of the screen. I would like that when I tap somewhere outside this view, it disappears.

I thought about adding another transparent UIView right under MyView and add a tab gesture on it with the dismiss function but I'm sure there is something cleaner than this.

So I thought about adding the tap gesture MyTapGesture to dismiss MyView on self.view of the UIViewController. The problem is that outside this view, I have other UIControls and gestures that capture also any touch at the same time than MyTapGesture.

How can I make MyTapGesture the priority gesture outside MyView and ignore all other gesture, taps, etc...?

You may have to use the gesture delegate methods to handle two tapGestureRecognizer activate the one you need depending on scenario

#pragma mark - UIGestureRecognizerDelegate methods
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {

return YES;
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
   if ([tapGestureRecognizer1 isEqual:gestureRecognizer]) {

   return [tapGestureRecognizer2 isEqual:otherGestureRecognizer];
   }

 if ([tapGestureRecognizer2 isEqual:gestureRecognizer]) {

return [tapGestureRecognizer1 isEqual:otherGestureRecognizer];
}

return NO;
}
