How do I force an app to always start from scratch

Question

I'm working on an app that needs to run through a protocol from beginning to end. How do I force the app to always start at the beginning when brought back from the background, regardless of where it was left. Thanks

Answer 1

write your application starting code in applicationDidBecomeActive method, because this method calls both time when you start your application first time & also when you cames from background

Answer 2

One option is to use exit(). However, that method is only useful for testing/programming purposes. Apple will not accept that being in your code.

Another option would be to create a global session similar to the method used by most social media API's, and in your App Delegate's:

- (void)applicationDidEnterBackground:(UIApplication *)application

set the global session to closed. Then just set your protocol logic to restart if the session is closed.

I hope that helps!

Answer 3

If your goal is to restart the app from scratch at every start up, simply add/change the key UIApplicationExitsOnSuspend to YES in your info.plist file
