What is the difference between loadView and viewDidLoad?

Question

I know that there seems to be an exact duplicate of this question: iPhone SDK: what is the difference between loadView and viewDidLoad? However, I read this question and still have not received a complete answer. I do not use IB as the user interface is dynamic.

So, I have to create self.view and then add subviews to loadView.

or do I need to create self.view in loadView and add subviews to viewDidLoad? #

        If you override this method, your implementation is

non-nil view.

        If you do not override this method, the default implementation uses 

nibName nibBundle , nib. nib , nib, .

  * The view controller calls its viewDidLoad method to perform any

Use viewDidLoadto initialize views and construct. And use loadViewif you don't have Nib / Xib and you want your ViewController to have a custom (not UIView) look.
