iOS Swift Segues

Question

What I want: When I'm on my green screen and push the button "PushToBrown" I want the brown screen "think" that I'm coming from blue. So if push the back Button in my brown screen I always want to go back to blue.

At the moment: I call from my green screen programmatically for example performSegueWithIdentifier(..., nil) and can switch to brown or just implement it by drag&drop (from the button "PushToBrown" to the brownVC screen). But if push the "back Button" I go back to Green. -> How can I tell brown he should always go back to blue?

I suppose that's a problem with the navigation Controller. You could also help me if you know some really good tutorials for segues or navigationcontroller handlding.

Thanks in advance!

The solution for your problem would be unwind segue : What are Unwind segues for and how do you use them?

What you should do ( as you can see in the link ) is add exit point, create unwind method and call that one instead of simple popViewcontroller. The first answer contains both explanation, code examples, and both Objective-C and swift

And this will also work with the "BackButton" in the TopBar? – S. Birklin Jul 22 '15 at 14:40
Sure thing, you just have to set your own event to go "back". In other words, you will have to create uibarbutton with event for unwind segue – Miknash Jul 22 '15 at 14:54
