title: How can I assign the UIBarButtonSystemItemAction icon to a UIButton?
body: <p>I have a UIButton within a UITableViewCell and I would like to assign the standard 'Action' icon to this button.</p>
  
  <p>This icon is normally associated with a UIBarButtonItem by assigning the icon to UIBarButtonSystemItemAction, however I cannot add a UIBarButtonItem into the UITableViewCell's view and therefore I would like to know if it's possible to assign this icon to a plain UIButton?</p>
  
  <p>Thanks,</p>
