ios9 - Can an 'Unwind Segue' work between two storyboards connected by a storyboard reference?

Question

In iOS 9, storyboards can be connected by a 'storyboard reference' that links to a second storyboard by adding a storyboard reference and setting the 'referenced ID' to the name of another storyboard file.

Is it possible to set up an unwind segue in the second file that unwinds to a scene in the first file? If so, what steps are involved, either in Interface Builder or in code?

Answer 1

I didn't have to make a storyboard reference back from the 2nd storyboard to the first as Ryan laid out. For me, in my second storyboard I could Control-drag from a viewcontroller to its own exit, and the unwind segue that I had specified in a viewcontroller class consumed in the first storyboard appeared. So I just selected that to create a new exit segue with an identifier, and called performSegueWithIdentifier: on it in code. Worked fine.
