title: Find which child view was tapped when using UITapGestureRecognizer
body: <p>How do I know on which of the the child views an event occurred when using UIGestureRecognizers?</p>
  
  <p>According to the documentation:</p>
  
  <blockquote>
    <p>A gesture recognizer operates on
    touches hit-tested to a specific view
    and all of that view’s subviews.</p>
  </blockquote>
  
  <p>As far as I can see, the 'view' property is</p>
  
  <blockquote>
    <p>The view the gesture recognizer is
    attached to.</p>
  </blockquote>
  
  <p>which will be the parent view.</p>
