iPhone: Restart the app after clicking on a button?

My app has a logout button and when the user hits that button, I need to kill all the existing views and background tasks (though I don't want to see the launch image again).

How can I accomplish this?

The way I usually handle this is to have the LoginViewController be the RootViewController of the app with a NavigationController. On the LoginController I set the NavigationBar to be hidden.

Then it's just a simple.

[self.navigationController popToRootViewControllerAnimated:NO];

And all of your views are gone/killed (if you built them properly) so you'll only have to handle killing off any background processes that are not managed by the views.

In order to kill the views, just change the rootViewController property of the window.

Something like

self.window.rootViewController = //The new view controller to be presented here

In order to kill the background tasks it depends on the nature of the tasks. If you have a reference to them, you can kill them manually when logging out.
