title: Prevent UITableView from scrolling to cell containing textField
body: <p>UITableView appears to have some automatic behaviour where, if a cell contains a textField or textView, and that field or view becomes first responder, the tableView scrolls itself so that the the cell is not obscured by the keyboard. I'm sure that, in most cases, this is very handy.</p>
  
  <p>In my case it's no good. The tableView is within a smaller containerView, and the default behaviour leaves the field still obscured. I want to handle moving the whole container myself, and the default scrolling behaviour is getting in the way.</p>
  
  <p>Does anyone know how I can "turn off" this feature of UITableView? </p>
