One caveat: If you drop an SDK from a version of XCode downloaded by a different Apple ID, the App Store will show that you have an update to 4.5.1 (even though you already have it). What you do within the implementation doesn't matter, either. I was able to build against the 5.1 SDK with XCode 4.5.1. The name of the method and variable don't matter. So what you need to do is give the view that you want to back all the way out to, in this case, A, an instance method which is marked as a IBAction and takes in a single parameter of type UIStoryboardSegue *. You want to have a button on view Z which allows the user to go all the way back to A. Imagine you have a sequence of views in your storyboard:

Here is a technical note from Apple regarding this topic. (From iOS6 docset > General > Getting Started) And here is a nice example of how you can implement one However, the Exit objectĮnables a view controller to unwind to an arbitrary scene.

Originally transitioned to the child scene. Unwinds (or returns) to the parent scene-that is the scene that By default, whenĪ user dismisses a child scene, the view controller for that scene Here is some more info on the subject from Apple's documentationĪ placeholder object named Exit for unwinding seques.

You can just login to Apple's iOS Dev Center with your developer account details and then go to the WWDC 2012 videos page and watch 'Adopting Storyboard in your App' (it's fifth from the top) The discussion of unwind segues starts at time 37:20. The good news is that there is a session from WWDC 2012 explaining those creatures (among other things). Unwind segues can allow transitioning to existing instances of scenes Unfortunately there's no documentation for this so far except a brief mention on XCode 4.5 new features list that states:
