title: Detect Touch Event On UIScrollView's Content
body: <p>I have a UIScrollview with UIImageView's inside it.</p>
  
  <p>If I add gestures to the UIImageView before they are added to the scrollview, the touch event is not fired.</p>
  
  <p>I want to get the UIImageView that a tap occurs at.</p>
  
  <p>I have seen some answers that touch about getting the point of the touch from the UIScrollView and then calculating the UIImageView based on the position --- but that seems really messy and overkill.</p>
  
  <p>Is there a simple way to get a touch event from an object inside a UIScrollView?</p>
