title: contentInset not working with UISearchDisplayController tableView?
body: <p>Using <code>UISearchDisplayController</code>, I am showing a <code>UIView</code> in bottom so causes hiding the filtered data while scrolling the table. I used <code>contentInset</code> property to show data in bottom.</p>
  
  <p>My problem is that <code>NSStringFromUIEdgeInsets(self.searchDisplayController.searchResultsTableView.contentInset)</code> is showing the <code>bottom</code> value as <code>216</code> even if I reset the UIEdgeInsetsZero.</p>
  
  <p>When I do multiple search the more data is not visible after scrolling:</p>
