title: New solution to detect tableView reloadData completion?
body: <p>I need to detect when a tableview has finished reloading data.  There was an older solution where you could subclass the tableview then overload the reloadData method, however apparently that no longer works because tables are handled on multiple threads now and reloadData is called before cellForRowAtIndexPath.</p>
  
  <p>My question is, has there been any solution to this problem since the change?</p>
  
  <p>My problem is I am losing the pointer to a textField when the table reloads its data, so the first responder I am trying to set to the next text field (to auto focus on the next data input field), is lost.</p>
