Possible Duplicate: Adding Core Data to existing iPhone project how can I add core

Possible Duplicate:
Adding Core Data to existing iPhone project

how can I add core data into an existing iOS project? I added the data model file, created the data models from it and added the three properties into my app delegate all into my existing(!) project. I also added CoreData into the frameworks.

In my app delegate’s didFinishLaunching-method I call [self managedObjectContext], but it returns nil. I guess I have to override the getter methods and load my data model from there? How do I do that?

    Easiest way to do this is to create a new project (Empty project) and make sure Core Data is added in. Then, just look over the differences, there should be four big ones:

    1. Add in all the stuff that is created in the AppDelegate
    2. Add in the Core Data framework
    3. Add your data object
    4. Modify the pch file
