title: Left Bar Button Item - show name of previous View Controller
body: <p>If you have a Navigation Controller with no Bar Button Items, a navigation <strong>back button</strong> will be shown with the <strong>name of the last View Controller</strong>.</p>
  <p>I want to keep that name, as in I don't want to have to hardcode it. I do know how to add it in but I don't want to have to do that because that leaves more room for bugs.</p>
  <p>Is there a way that I can have a left Bar Button Item and for the default one to not go away?</p>
