title: How to ensure UITableViewCell is visible?
body: <p>I'm using an InputAccessoryView so a toolbar appears on top of my keyboard for an iPhone app.  When the keyboard appears it scrolls the UITableView up so the cell becoming first responder is in view.  When I tap "Next" on my keyboard which moves the focus to the next UITableView row the cell is beneath the InputAccessoryView now.</p>
  
  <p>How can I ensure the active cell is in view and not covered up by the InputAccessoryView?</p>
  
  <p>Thank you.</p>
