Question

I am developing an application in which i am using location service.

Basically that app show that if u get any missed call at which place.

For this i have use core-location and core telephony frame works. But when i am testing app then location service not working in background.
I have use this code for didfinishlaunching.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

    UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey]; 

    if (localNotif)
        application.applicationIconBadgeNumber = localNotif.applicationIconBadgeNumber-1; 
    locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    locationManager.distanceFilter = kCLDistanceFilterNone; // whenever we move
    locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters; // 100 m
    [locationManager startUpdatingLocation];
    [self callinbackground];

    [self.window makeKeyAndVisible];
    return YES;
}

and app goes in background then i have write down code form this link:-

But when app goes in background then not working. How i fixed it?

Thanks in advance…
