-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{

    NSLog(@"%@",error.userInfo);
    if([CLLocationManager locationServicesEnabled]){

        NSLog(@"Location Services Enabled");

        if([CLLocationManager authorizationStatus]==kCLAuthorizationStatusDenied){
         UIAlertView    *alert = [[UIAlertView alloc] initWithTitle:@"App Permission Denied"
                                               message:@"To re-enable, please go to Settings and turn on Location Service for this app."
                                              delegate:nil
                                     cancelButtonTitle:@"OK"
                                     otherButtonTitles:nil];
            [alert show];
        }
    }
 }

Reason behind this, this method will call when your service will be disable the location service. this code is useful for me.
