title: UITextField in UITableView to becomeFirstResponder
body: <p>I have a problem which I dont have a clue how to work around. Maybe anyone of you could help me to the correct directions...  </p>
  
  <p>Simple I have a UITableView with each cell containing a UITextField.   When I´m editing a cell (UITextField) and hit Return Key, a new row is inserted under the current cell.  After that I reloadData on the TableView, the new row is showed. Everything is OK here. </p>
  
  <p>Now to my problem,  I want to [UITextField becomeFirstResponder] on the newest added row.  But I could not find anyway to accomplish this.  I could post code but didn't find that necessary.  </p>
  
  <p>Cheers.  </p>
