title: Search controller below navigation item prior to iOS 11
body: <p>I am using this code with no problem, but I would like to place the search controller below the navigation item’s <code>titleView</code>, instead of replacing it. With iOS11 it’s as easy as setting <code>navigationItem.searchController</code> to the <code>searchController</code>, and it will place it below the <code>titleView</code>, but in the <code>navigationItem</code>.</p>
  
  <p>Any ideas on how to do this prior to iOS 11, instead of replacing the <code>titleView</code>?</p>
  
  <p>Current Code:</p>
  
  <pre><code>if #available(iOS 11, *) {
      navigationItem.searchController = searchController
      navigationItem.hidesSearchBarWhenScrolling = false
  } else {
      navigationItem.titleView = searchController.searchBar
  }
  </code></pre>
