title: UITapGestureRecognizer to dimiss keyboard overrides button
body: <p>I have a couple of UITextField and UIButton inside a UIScrollView and this scroll view is inside a view of my UIViewController. I added a touch gesture recognizer to dismiss the keyboard if shown:</p>
  
  <pre><code>UITapGestureRecognizer *tapToDismissKeyboard = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)];
      [tapToDismissKeyboard setCancelsTouchesInView:NO];
      tapToDismissKeyboard.delegate = self;
      [self.view addGestureRecognizer:tapToDismissKeyboard];
  
  #pragma mark UITapGestureRecognizerDelegate
  - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
      if ([touch.view isDescendantOfView:self.signupButton_] || [touch.view isDescendantOfView:self.profilePictureImageView_] || [touch.view isDescendantOfView:self.signupUsingFacebook_]) {
          return NO; // ignore the touch
      }
  
      return YES; // handle the touch
  }
  </code></pre>
  
  <p>The issue is that when I tap the signin/signup button it still detects the tap gesture, in which I actually want the button touch.</p>
