passing data back to a previously allocated UIViewController

Question

I have a view controller that then has a button that passes to an option menu.

When options are set they need to be past back to the previously allocated viewcontroller.

Answer 1

You could use a shared singleton? http://cocoawithlove.com/2008/11/singletons-appdelegates-and-top-level.html

Or save the parameters to nsuserdefaults and read them back in in your first viewcontroller

or some other temporary store such as your appdelegate

I've used all three of the above approaches before.
