How to cancel UIGestureRecognizer if subview's button pressed

Apple documentation shows the answer:

- (void)viewDidLoad {
      [super viewDidLoad];
      // Add the delegate to the tap gesture recognizer
      self.tapGestureRecognizer.delegate = self;
}

// Implement the UIGestureRecognizerDelegate method
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:    (UITouch *)touch {
      // Determine if the touch is inside the custom subview
     if ([touch view] == self.customSubview){
         // If it is, prevent all of the delegate's gesture recognizers
         // from receiving the touch
        return NO;
     }
     return YES;
}

Of course in this case customSubview would be subview on the page that has buttons in it (or even the buttons on it)
