title: How to limit gesture recognizer within a specific view
body: <p>I have one imageView set up and I have added a <code>UIView</code> on that imageView. The <code>UIView</code> is transparent, Now I am adding some more <code>ImageViews</code> on that <code>UIView</code> dynamically. </p>
  
  <p>I want set up Pan and Pinch Zoom gesture recognizers on that ImageViews that I am adding dynamically, but I dont get how can we limit the gestures recognizers operating range.?</p>
  
  <p>When the image that is dragged using the Pan gesture,It should remain within that <code>UIView</code> and must not be dragged out of the borders of that <code>UIView</code>. </p>
  
  <p>My <code>UIView</code> covers only half of the screen. </p>
  
  <p>Any ideas on how can we achieve this? </p>
