Do I always have to call [super viewDidLoad] in the -viewDidLoad method?

Question

In Apple\'s scrollView example they don\'t call that. I always thought that\'s a must. Why should I call that anyways?

Answer 1

As Markus says, UIViewController doesn't do anything in its viewDidLoad method, so you don't have to call it. However, it's a good habit to get into, in case you change your inheritance structure and suddenly the class that used to inherit from UIViewController now inherits from something that does do something in the viewDidLoad method.
