I would like to find a way to see what app is running in foreground or if the home screen is displayed when a local notification from my app show up. For example i want to have different actions if there is in homescreen or in someone else app. I tried to use processed and pid but the pid is generated hen the app starts and not the last time the app is used. Any idea? thanks

As described in the push notification documentation you can read [[UIApplication sharedApplication] applicationState] when you receive the notification to determine whether your app is in foreground, inactive (it's visible but a dialog like the WiFi chooser is in front) or in background.
