title: UITabBarController's 'More' navigation controller disappears under UINavigationController
body: <p>I am using a UITabBarController as well as a UINavigationController on my app.</p>
  
  <p>In my UITabBarController I am using more than 5 items so I automatically get the 'More' item.
  I've managed to add a saving procedure so the order of those items will be kept in case somebody changes the order etc.</p>
  
  <p>With 'More' active I get the More navigation controller with the 'Edit' item positioned under my UINavigationController. Both navigation controller are visible. When I click on 'Edit though the More navigation controller disappears and seem to be hiding under my UINavigationController and therefore I can't see/use the 'Done' function to save my new order</p>
  
  <p>What did I miss?</p>
  
  <p>Cheers</p>
