Question

I have added Tap Gesture recognizer to a view. My view has an image and a UIToolBar at the bottom with a few UIBarbuttons I want to cancel any touches on these buttons. I am trying to use the following method to cancel the touch. How do I detect whether the touch is on the toolbar or any bar buttons? Frame is also not defined for Bar buttons…

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {


    if (gestureRecognizer == tapRecognizer) {
  if (touch.view==barbutton/*toolbar or bar button item*/) 
   {
   return NO;   
  }

    }
    return YES;
}

Answer 1

CGPoint location = [touch locationInView:self.view];
if(CGRectContainsPoint(toolbar.frame, location)) { ... }

This is assuming the toolbar and self.view are in the same coordinate space. If not, you’ll have to use UIView’s coordinate conversion methods (convertPoint:toView:) to make the spaces match.
