viewDidLoad is called twice

Question

My viewDidLoad in a view controller is called twice. Once by [UIViewController View] and a second time by [UINib instanciateWithOwner:Option

Answer 1

In my case, I used self.view (once) in viewDidLoad while calling viewDidLoad in my unit tests. This resulted in two calls. However, when I replaced [testedViewController viewDidLoad] with [testedViewController view], the double call problem was gone.
