Answer 1

Use your CLLocationManagerDelegate's locationManager: didFailWithError: method and check for a kCLErrorDenied error to see if the user denied location services.

- (void)viewDidLoad
{
    locationManager = [[CLLocationManager alloc] init];

    locationManager.delegate = self;

    locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;

    // Set a movement threshold for new events.

    locationManager.distanceFilter = 500;

    [locationManager startUpdatingLocation];
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)locationManager:(CLLocationManager *)manager

     didUpdateLocations:(NSArray *)locations {

    // If it's a relatively recent event, turn off updates to save power

}

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

    NSLog(@"%@",error);
}

if location service disable for your app then its give you error

Error Domain=kCLErrorDomain Code=1 "The operation couldn’t be completed. (kCLErrorDomain error 1.)"
