title: How to add a sticky searchbar to UITableViewController
body: <p>i tried to add a sticky searchbar to my UItableViewController which is embedded inside a tabBarController. But i dont get it. I tried something out with a containerView, but i thought this couldnt be the right way to do this. Is there any best practice to add a sticky searchbar on top of a tableView ?</p>
  
  <p>Thanks. </p>
