title: UISearchBar in UINavigationController introduces ~60px offset in SearchResultsTable
body: <p>As soon as I display my search bar in the navigation controller, the behavior of the search results table changes - the table content is offset vertically by about 60px.</p>
  
  <p><img src="https://i.imgur.com/3gziDYj.png" alt="offset results"></p>
  
  <p>Changing the table's contentOffset on the delegate ResultsWill/Did Appear makes no difference.</p>
  
  <p>Setting displayInNavigationController = false restores expected alignment of results (directly below search bar with no gap).  </p>
  
  <p>The blank area appears to be part of the table/scrollview, as I can force the results cells to temporarily display in the blank section by scrolling down.</p>
  
  <p>Any idea how to get those first result cells to display at the top of the results window?</p>
