Hmm. I never did that...but perhaps that's my problem?
My code looks like...
MyAppDelegate* delegate = [[NSApplication sharedApplication] delegate];
NSManagedObjectContext* db = [delegate managedObjectContext];
NSEntityDescription* entity = [NSEntityDescription entityForName:
@"MyObject" inManagedObjectContext: db];
MyObject* object = [[MyObject alloc] initWithEntity: entity
insertIntoManagedObjectContext: db];
Am I missing something? I want to learn. :)
