Note: Does creating a delegate protocol for each screen that you want to reach through a segue sound like a lot of work? That’s what the creators of UIKit thought too, so in iOS 6 they introduced a new concept: the unwind segue. With this new feature you can create segues that go back to the previous screen. That is what the green Exit icon is for in the storyboard. If you want to learn more about unwind segues, we’ve dedicated a chapter to it in iOS 6 by Tutorials.
