title: gesture recognizer for whole UIView
body: <p>I want to find a way to animate a whole UIView which contains some ui components within it. Here's my code snippet:</p>
  
  <pre><code>UIRotationGestureRecognizer *rotationGesture = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotatePiece:)];
  [piece addGestureRecognizer:rotationGesture];
  [rotationGesture release];
  </code></pre>
  
  <p>the "piece" is a uiview here which I want to rotate and it works perfectly fine. But when I add some other UI components (like UIbutton) inside it (piece view), gestures are not recognized properly when user touches on those UI components. Essentially, I want the parent to listen to the gestures even when user touches the child object.</p>
  
  <p>Any ideas?</p>
