title: Empty UISearchbar space when combining search bar with Nav bar in iOS7?
body: <p>So I was trying to combine the search bar with the Nav bar for tableview in iOS7.</p>
  
  <p>I called<br>
  <code>self.searchDisplayController.displaysSearchBarInNavigationBar = YES;</code>
  And it looks fine.</p>
  
  <p>However, there is a very annoying empty space (roughly the size of a searhbar) between the nav bar and the first tableview content!</p>
  
  <p>I'm wondering what exactly did I miss here?</p>
