'+entityForName: nil is not a legal NSManagedObjectContext parameter - Core Data

Question

I have added all of the relevant code to the App Delegate, and I am able to add to the data model and fetch from the data model in applicationDidFinishLaunchingWithOptions.<

Answer 1

you should add this to your viewController:

 id delegate = [[UIApplication sharedApplication] delegate];
    self.managedObjectContext = [delegate managedObjectContext];
