I think the question is, how do you write code to "log out" your app and clear all of the data in all of the views across a tab bar controller?

If I can help translate, I think the scenario is essentially this:

He has an app with two view controllers in MainWindow.xib, a UIViewController and a UITabBarController. Both are hooked up to IBOutlet properties on his app delegate. When the app loads, the app delegate instantiates both controllers automatically, and he shows the UIViewController with a login form.

When the user logs in, it uses some technique to hide the UIViewController and show the UITabBarController.

On a view in one of the tabs in the UITabBarController, there is a logout button. When the button is tapped, it removes the UITabBarController from the superview and shows the login UIViewController.

When the user logs in again, the UITabBarController has remained in memory, so the state has not changed since logging out. All of the data on all of the tab views needs to be reset.

What's the best practice to scrap the UITabBarController and reinstantiate it?

You can't use the following, since MainWindow.xib contains your app delegate, and another UIViewController, not just your UITabBarController:

tabBarController = [[UITabBarController alloc] initWithNibName:"MainWindow" bundle:nil];
