title: iOS7 searchBar and tableView cells have gap when searchDisplayController is active
body: <p>I have a <code>UISearchBar</code> within my <code>UITableView</code>. When the <code>UISearchBarController</code> is activated, the table view does not move up with the search bar, instead a gap is left between them.</p>
  
  <p><img src="https://i.stack.imgur.com/4X491.png" alt="1. Gap between Search Bar with Scope Bar and Table View"></p>
  
  <p>Even if I get rid of the scope bar, the gap still exists as below:</p>

  <p>Here is a link to sample project I was using <a href="https://github.com/msec/TestSearchDisplayController" rel="nofollow noreferrer">https://github.com/msec/TestSearchDisplayController</a></p>
  
  <p>Note this gap does not appear in the apple mail and contacts app.</p>
  
  <p>Any help would be greatly appreciated</p>
