title: Add subview to tableview which doesn't scroll
body: <p>I'm using a UITableViewController and want to add a searchbar.</p>
  
  <p>My options are <code>[self.tableview addSubview:searchBar]</code> or <code>self.tableview.tableHeaderView = searchBar</code>
  Both options will scroll the searchbar along the rest of the tableview, which I understand. But is there a way to lock elements up, instead of using a UIViewController or changing the frame origin on scroll?
  I'm thinking of a way to get above the current view hierarchy and add a subview onto that.</p>
  
  <p>I tried the opposite approach, to add a view to the superview and bring that to front </p>
  
  <p><code>[[self.tableView superview] addSubview:searchBar];
   [[self.tableView superview] bringSubviewToFront:searchBar];</code>
  }</p>
  
  <p>but it didn't work.</p>
