title: Add floating view (i.e. static and fixed) to UITableViewController
body: <p>I'm trying to add a custom subview to a <code>UITableViewController</code> that doesn't move when the user scrolls.</p>
  
  <p>Is it possible to add such a view?</p>
  
  <p>I'm using a <code>UITableViewController</code>. I would switch to a <code>UIViewController</code> and add a <code>UITableView</code>, but the code relies on the UITableViewController's <code>refreshControl</code>. Adding a container view and having two controllers seems a bit much for such a simple task!</p>
  
  <p>I've also tried adding the content to the <code>UINavigationController</code> view, but unfortunately it doesn't animate smoothly when the view controller appears and disappears.</p>
  
  <p>Is there any way to add a fixed subview to a <code>UITableView</code>?</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Adding a container view and having two controllers (with an embed segue) is difficult for this project, since I'm updating an older code base and there is a lot of legacy code that depends on the main controller being a <code>UITableViewController</code>. Is there any way to achieve this without an embed segue / two view controllers?</p>
