Without knowing exactly what you want to do, this might be totally overkill, but it might help you.

You could subclass the UIViewController (e.g. the AddToArrayViewController), and in the custom init method add it to some Singleton you have defined somewhere.

BUT, you need to make sure you also remove the ViewControllers when they are removed/cleaned up, otherwise you will just have a list of dangling pointers in that array, which is not really safe.
