My app runs fine without implementing the appDelegate.m with:
BNRQuizViewController *quizVC = [[BNRQuizViewController alloc] init];
self.window.rootViewController = quizVC;
Whats the point of this?
Also I implemented the viewDidLoad method in the View Controller instead of the initWithNibName:bundle: method and my app runs fine so what is the purpose of doing it this way??
