title: UISearchController's search bar overlaps first tableview cell
body: <p>I am using <code>UISearchController</code> and the <code>UISearchBar</code> also has a scope bar. The search bar is added as a subview to a <code>UIView</code> which is above the <code>UItableView</code>. I have done it this way since I want the search bar to be always visible even when the tableview is scrolled.</p>
  <p>The problem is the scopebar overlaps the first tableview cell</p>

  <p>Scope bar overlapping the tableview cell</p>

  <p>How can I prevent this overlapping?, I can't display the searchbar in navigationbar since the scopebar when placed in navigation bar does not get displayed.</p>
