title: Is there any way to save a UIView to png without capturing the whole screen
body: <p>What I'm trying to do is save a UIView that receives user input as drawings, and save the drawing only, without the background, that way as a setting in the app, the user can change out the background images they are drawing on.</p>
  
  <p>I've found lots of code for doing screen captures, but nothing on saving just a single UIView.</p>
  
  <p>Any suggestions?</p>
