title: is groupTableViewBackgroundColor deprecated on iOS 6?
body: <p>I was just testing my app with iOS 6.0 and Xcode 4.5GM and I have set up a view like this:</p>
  
  <pre><code>[self.view setBackgroundColor:[UIColor groupTableViewBackgroundColor]];
  </code></pre>
  
  <p>So, the view has the same pattern than a common table view.</p>
  
  <p>This works fine on iOS 4 and 5, but in iOS 6 it just gives me a white background.</p>
  
  <p>Is this deprecated? If so, how can I replace it?</p>
  
  <p>Thanks</p>
