title: UIPanGestureRecognizer not being fired for UIImageView outside its SuperView area?
body: <p>I have the following UI on an iPad app: </p>
  
  <p><img src="https://i.stack.imgur.com/W8fHn.png" alt="enter image description here"></p>
  
  <p>Here is an explanation of what's going on:</p>
  
  <ol>
  <li>Blue area is the View attached to the (displayed) ViewController.</li>
  <li>Yellow area is an UIImageView where users can drag items around (what I call the live area).  Yellow is a subview of blue area.</li>
  <li>Red item is an UIImageView that has a UIPanGestureRecognizer attached.  Its a subview of yellow area.</li>
  <li>Red item can be dragged, as long as the dragging starts from inside the live (yellow) area.</li>
  </ol>
  
  <p>On the situation on the image shown above, I want to be able to drag the red item from any point on its surface. (not only from the area where it intersects the (yellow) area)  </p>
  
  <p>Any ideas?</p>
  
  <p>Thanks!</p>
