If you prefer to receive callbacks instead of "ask" about the application state, use these two methods in your AppDelegate:

- (void)applicationDidBecomeActive:(UIApplication *)application {
    NSLog(@"app is actvie now");
}


- (void)applicationWillResignActive:(UIApplication *)application {
    NSLog(@"app is not actvie now");
}
