Embed managedObjectContext in the initial viewController?

Question

I am customizing the Core Data ( UIManagedDocument ) model in my AppDelegate and I was curious how I could add a reference to NSManagedObjectContext to my (storyboards) Initial viewController.

I could access it directly in viewControllers viewDidLoad using [ [[UIApplication sharedApplication] delegate] sampleDatabase] managedObjectContext] , and then pass it to additional controllers using prepareForSegue .

I'm just wondering if there is an initial segue (or mechanism) that would allow me to pass (or add) a managed ObjectContext to this initial viewController without having access to it, using the appDelegates sharing instance once inside the controller?

Answer 1

When you use the storyboard, the source view controller is set as the rootViewController property of your delegate just before application:didFinishLaunchingWithOptions: called.

You should be able to use the listing on this link to set the property, assuming that by this time your master data structure will be created.

Usually you just have a property on the view controller, which is NSManagedObjectContext, and just set this property right after initializing the viewController in the appDelegate application. myViewController.managedObjectContext = self.managedObjectContext
