title: Back in navigation bar without navigation controller (like Activity.this.finish() in android)?
body: <p>I have background in android, and in short every screen there is Activity pushed on stack, when I call Activity.this.finish() on that activity it removes from stack and app backs on previous screen (behavior like back button). In ios 6 app I have navigation bar ( it is not embedded in a navigation controller, is there any way to call something to destroy current controller and come back on previous ? </p>
