Logical Question: How to make a LogOut on iPhone App?

I want to have a login / logout on my iPhone App.

I have a AppDelegate which routes by TTNavigator to my MainView.

My MainView shows a the LoginView with presentModalViewController.

Know my question is开发者_运维问答, how to do a logout? Simply show the LoginView again?

What i'd do is destroy any credentials you may have stored in Memory or in a Dictionary/Keychain and also close any pending sessions. Then you can just show the LoginView again.
