title: UISearchController UISegmentedControl deselect all items
body: <p>Is there a way to deselect all item of <code>UISegmentedControl</code> in <code>UISearchController</code>? I need to deselect some segment if i tap on a already selected segment. So i will enable all options for search. Only what i can do now for that - create segment "All", but i already have 3 segments. I just have no space for more segments (they all are disappear if i add new one). Thanks.</p>
  
  <p><strong>UPD</strong></p>
  
  <p>Still can't find way to get access to <code>UISegmentedControl</code> of <code>UISearchController.SearchBar</code></p>
