title: Round corners on UITableView
body: <p>What is the best way to get round corners on an entire UITableView as seen in Stocks and Spotlight? The grouped style doesn't solve the problem because the round corners scroll away with the cell. I'm trying to clip the view so the corners are always round regardless of scroll position.  </p>
  
  <p>I saw another discussion about doing this to a UIImage that suggested masking it with another image. I'm not sure if this would work because I need taps to pass through to the table. This isn't isn't ideal for me because I want the background pattern to show through through the corners. </p>
