title: UISearchController Not Redisplaying Navigation Bar on Rotate
body: <p>I have implemented the UISearchController and it is working great except...</p>
  
  <p>When I click on the Search Bar the Navigation Bar disappears nicely as expected. When I rotate the phone to landscape view I get this view which makes sense.</p>

  <p>However, when I rotate the phone back to portrait view (still selected in search type area) I get this following view.</p>

  <p>You can see that the Navigation Bar never reappears. I feel I'm implementing a basic search controller. <strong>What could possibly be causing this?</strong> </p>
  
  <pre><code>self.venueSearchController = [[UISearchController alloc] initWithSearchResultsController:nil];
  self.venueSearchController.searchResultsUpdater = self;
  self.venueSearchController.searchBar.delegate = self;
  self.venueSearchController.dimsBackgroundDuringPresentation = NO;
  self.venueSearchController.hidesNavigationBarDuringPresentation = YES;
  self.venueSearchController.searchBar.frame = CGRectMake(self.venueSearchController.searchBar.frame.origin.x, self.venueSearchController.searchBar.frame.origin.y, self.venueSearchController.searchBar.frame.size.width, 44.0);
  
  self.definesPresentationContext = YES;
  
  self.navigationController.navigationBar.translucent = YES;
  self.venueSearchController.searchBar.translucent = YES;
  
  self.tableView.tableHeaderView = self.venueSearchController.searchBar;
  </code></pre>
