title: Auto Layout with navigation bar and view controller (iOS 7)
body: <p>I'm currently transiting my application to iOS 7 (I want it to remain iOS 6 compatible). This question is not covered by the Apple NDA, it is a question about Auto Layout (it seems that iOS 7 forces Auto Layout (EDIT : was wrong, it is not forced)).</p>
  
  <p>I have a navigation controller with a root view controller (obvious). With iOS 6, i was not using Auto Layout, so the root view controllers was below the navigation bar. With iOS 7, the frame origin does not include the navigation bar, so the top part of my content is hidden...</p>
  
  <p>Have you an idea how to make the entire view above the navigation bar with Auto Layout ?</p>
  
  <p>Thanks !</p>
