iOS Getting Data Back from an NSPopover

EDIT: Opps. I posted this in the Mac section and not the IOS section. sorry

I created my first popover for an iPad app. I need to return a value back from it when it is pressed. But in making it I can see that I am basically creating a new UIViewController class and it is easy to push information to it while you are.

So getting the info back to my first view controller I would use NSUserDefaults or a Singleton which I have never experimented with yet as a global variable?

I am wondering what is the best way if anyone can recommend something for returning data to the first ViewController?

Thanks.

I have not looked at that. But I will. I looked at something like that a little but looked kind of confusing. I will check out the picker you recommended. I can always go back to using plists for data transfer but wanted to learn something new.

Thanks for the help.

I ended up passing this data with a singleton. I learned how to create and use them today, a very handy tool. I used the popoverControllerDidDismissPopover: in the first view controller to fetch the data from the singleton and assign it to the UILable in the first viewController.
