title: UISearchBar displaysSearchBarInNavigationBar
body: <p>I want to replicate the functionality of the Twitter app where the search bar slides in to the navigation bar.</p>
  <p>However I have run into a problem. If I don't add</p>
  <pre><code>[self.searchDisplayController setDisplaysSearchBarInNavigationBar:YES];
  </code></pre>
  <p>into viewDidLoad the bar will not appear. I have a search button in the righthand navigation item when I click it I call the above method. Is there anything I can do to ensure the search bar gets drawn.</p>
