title: "Auto Layout still required after executing -layoutSubviews" with UITableViewCell subclass
body: <p>Using XCode 4.5 and iOS 6, I'm developing an app with a simple table view with custom cells.  I've done this a hundred times in iOS 5 and below, but for some reason the new autoLayout system is giving me a lot of trouble.</p>
  
  <p>I setup my table view and prototype cell in IB, added subviews and wired them up as IBOutlets then setup my delegate and dataSource.  However now whenever the first cell is fetched from <code>cellForRowAtIndexPath</code>, I get the following error:</p>
  
  <blockquote>
    <p>*** Assertion failure in -[ShopCell layoutSublayersOfLayer:], /SourceCache/UIKit_Sim/UIKit-2372/UIView.m:5776</p>
    
    <p>*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Auto Layout still required after executing -layoutSubviews. ShopCell's implementation of -layoutSubviews needs to call super.'</p>
  </blockquote>
  
  <p>I haven't implemented a -layoutSubviews method in my subclassed cell (ShopCell), and even when I try to do that and add the super call as it suggests I still get the same error. If I remove the subviews from the cell in IB, and change it to a standard UITableViewCell, everything works as expected, though of course I'm left with no data in my cells.</p>
  
  <p>I'm almost certain that there's something simple I'm missing, but can't find any documentation or guides to suggest what I've done wrong.  Any help would be appreciated.</p>
  
  <p><strong>Edit:</strong> Just tried changing it to a UITableViewCell in IB and leaving all the subviews in place, still the same error.</p>
