How to use Core Data at 3rd level View of navigation

Question

Dear All, I am trying to build a navigation based iPhone application where I want to use Core Data modal at 3rd level view of navigation. The 1st and 2nd level view of this application are just simple tableViews. I have looked at the Apple CoreDataBooks application but there it used the methods for Core Data in the AppDelegate and RootViewController while I want to use these methods somewhere else. It is possible? Can somebody refer me to some tutorial for that? Thank you very much.

You can

1. Have your view controller create the Core Data stack.
2. Use [[UIApplication sharedApplication] delegate] to find the app delegate from anywhere, and ask it for a context.
3. Pass your context as an argument down through the view controllers.

It's a choice only you can make, based on the ways you expect your application to change in the future.
