Background processing is available for certain specific purposes. I'm not sure that yours is one of the allowed background tasks, but you can read about it in the Application Programming Guide.

You need to include the UIApplicationDelegates

- (void)applicationWillResignActive:(UIApplication*)application
- (void)applicationDidEnterBackground:(UIApplication*)application
- (void)applicationWillEnterForeground:(UIApplication*)application
- (void)applicationDidBecomeActive:(UIApplication*)application
