Does this objc code “shouldRestoreSecureApplicationState” restore app state when app is updated?

I have this code in appDelegate for an app game that's on App Store recently -

- (BOOL)application:(UIApplication *)application shouldSaveSecureApplicationState:(NSCoder *)coder {

return YES;

}

- (BOOL)application:(UIApplication *)application shouldRestoreSecureApplicationState:(NSCoder *)coder {


return YES;

}

Is that code ok as it is?

I understand that code preserves game states between sessions. But will it also preserve the game state when app is updated with a new version or new iOS?

Or is there some other code for that?

Thanks for your help
