title: UIView subview touch forward
body: <p>I have two custom UIViews (A and B respectively) each with a frame set to the same origin and same size.  They are both added to a parent UIView (C) as subviews. </p>
  
  <p>I have a touch recognizer as part of A and B that listen for touches on certain spots.  If that touch is received, it raises a delegate up to the parent UIView saying it has been touched.  The issue is that since B is added after A, B never receives a touch event.  </p>
  
  <p>The A and B UIViews are single lines with endpoints.  They both recognize touches on the endpoints and raise up delegate notifications.  How do I add subviews and recognize touches on them with parent views on top?  It's like an exclusivity thing.</p>
