title: How does the search display controller hide the navigation bar?
body: <p>When you enter the search bar handled by a search display controller, it slides the view up and pushes the navigation bar up with it. This is easy enough to do, however, when you click a search result and a new view is pushed on the navigation controller's stack, the navigation bar slides in from the right with the view!</p>
  
  <p>How is this done? If you simply set the navigation bar to hidden or shown, it happens instantly. I can't figure out how it seems to be hidden just for one view controller in the stack!</p>
  
  <p>Many thanks,</p>
