title: UIRefreshControl Background Color
body: <p>Is it possible to make the background of a UIRefreshControl grow as the control grows?</p>
  
  <p>I would like to have a colored background for the refresh control to match the top cell's background color. Changing the background color of the tableview is not acceptable because then empty cells at the bottom will also have the color, but I need them to stay white. </p>
  
  <p>Apple's mail app shows this behavior. The refresh control's background matches the gray search bar, but empty cells at the bottom of the table view are still the normal white.</p>
  
  <p>Here's an example screenshot of how the table looks showing the ugly white that appears as the refresh control is pulled:<br>
