iphone avoid save state

In my app I need to avoid the开发者_StackOverflow社区 saving state, in fact, I whis that each time the user starts the app, the app will be relaunced like the first time... how can I do?

Set UIApplicationExitsOnSuspend to YES (Boolean) in your Info.plist.

You don't have to do a thing. iOS does nothing to save the state of your app.
