title: willRotateToInterfaceOrientation not being called
body: <p>I'm returning <code>YES</code> in my view controller's <code>shouldAutorotateToInterfaceOrientation</code> function, and I can see using breakpoints that <code>YES</code> is being returned, however the <code>willRotateToInterfaceOrientation</code> method isn't being called, and nor is any other rotating method. It seems like after returning <code>YES</code> nothing happens!</p>
  
  <p>Any ideas?</p>
