I have an app that uses various view controllers as tabs. I'm in the process of saving the custom tab order when the app shuts down. I'm trying to find a generic identifier for my various view controllers without having to add an attribute to each controller (which my backup plan).
I would think, similar to UILabels, that maybe view controllers would support tagging or something similar? I'm having trouble finding in documentation so is there a way to tag or otherwise uniquely identify each view controllers in my UITabBarController?
