title: How to know which UIView or UIViewController receives a UITouch event or gesture?
body: <p>For debugging purposes, is there a way to know which view receives/processes a UITouch or gesture? I am looking for a generic approach rather than having to put NSLog into all UIView or UIViewController classes.</p>
  
  <p>I would like a global generic way to find out which view receives the touch or gesture by outputting its view tag.</p>
