title: How to draw graphics on a UIButton UIButtonTypeRoundedRect?
body: <p>How to draw graphics on a UIButton UIButtonTypeRoundedRect without subclassing... or do I have no choice?  Please note that the graphics around the rounded corners will vary with other functions... so the UIButton cannot interfere... otherwise I could have just used jpg images. 
  Or can I limit the border of the jpg image around the UIButton?</p>
  
  <p>thx</p>
