title: UIBarButtonSystemItem localizable
body: <p>How can I make UIBarbuttonItem localizable?</p>
  
  <p>My implementation:</p>
  
  <pre>
  UIBarButtonItem         *cancelButton = [[UIBarButtonItem alloc] 
                                               initWithBarButtonSystemItem:UIBarButtonSystemItemDone
                                               target:self
                                               action:@selector(cancel)];
  </pre>
  
  <p>Originally I thought that it is automatic, because it looks easy to make it like this, but looks like not. </p>
  
  <p>EDIT1: Official Apple dox says that cancel, done, edit, save buttons are localized, but not sure how to make it.</p>
