title: Subclassed UITableViewCell, make the delete button not show up
body: <p>I'm trying to mimic the behavior of the editable table cells in the contacts app. I've subclassed UITableViewCell, added my own UITextField, and setup behavior where if edit is pressed, the label gets hidden and my textfield becomes enabled, and shows, and vice versa. That part works fine.</p>
  
  <p>I don't want my users to be able to delete rows, but I'm having trouble finding where/how to disable and hide the delete button on the left of a cell itself. Any advice would be appreciated.</p>
