title: Zoom Loupe on UIImageView
body: <p>Does anyone know of a way to implement the zoom loupe functionality of a UITextField on the iphone in a UIImage view?</p>
  
  <p>Part of the app I'm building allows a user to draw a line on a UIImage, a process that might involve precision positioning of the points. In order to help the user, I want to provide the zoom loupe as seen when positioning the cursor in a UITextField. Does anyone have any idea as to how to do this? Any pointers to relevant docs?</p>
  
  <p>Cheers!</p>
