title: iOS - CALayer and Gesture/Swipe Recognizer
body: <p>I added a layer to my view to create gradient background color, but I need to use <code>UISwipeGestureRecognizer</code> in my view. The problem is that now, with the layer, the swipe recognizer doesn't work! How can I do?? Can I add a swipe recognizer to a layer?
  Thanks.</p>
