IBOutlet and viewDidUnload under ARC

Question

There is a similar question to this on SO here, however I just want to clarify something that wasn\'t fully explained there.

I understand that all delegates and outlets

Answer 1

I did a little testing and it appears that the code in the viewDidUnload method is unnecessary. To support this, the docs for viewDidUnload do actually say:

By the time this method is called, the view property is nil.

Indicating that the weak reference must have been set to nil automatically.
