title: UITableViewController not scrolling view when keyboard appears
body: <p>I have a <code>UITableViewController</code> with around 20 static cells, some of these cells have <code>UITextField</code>s within them and some are just for selecting with a checkmark.  The table is about 1.5 views worth so scrolling is required to get at the lower text fields.</p>
  
  <p>When I click within a textfield at the bottom of the table the keyboard pops up as it should but this then appears over the cell/textfield.</p>
  
  <p>I was under the impression (From Apple docs and elsewhere) that the <code>UITableViewController</code> class handles scrolling of the view automatically when a keyboard appears in any orientation and shifts the tableview up so that the cell is visible, this isn't happening though.</p>
