Узнать расстояние между 2 точками

Смотрите, есть такая ф-ция, которая определяет местоположение пользователя,

    - (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation{
    /* Получена информация о новом местоположении. */
    NSLog(@"Latitude = %f", newLocation.coordinate.latitude);
    NSLog(@"Longitude = %f", newLocation.coordinate.longitude);
}
- (void)locationManager:(CLLocationManager *)manager
       didFailWithError:(NSError *)error{
    /* Не удалось получить информацию о местоположении пользователя. */
}

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    if ([CLLocationManager locationServicesEnabled]){
        self.myLocationManager = [[CLLocationManager alloc] init];
        self.myLocationManager.delegate = self;
        [self.myLocationManager startUpdatingLocation];

и есть вот такая ф-ция, которая считает расстояние между двумя точками

    CLLocation *location1 = [[CLLocation alloc] initWithLatitude:59.957069 longitude:30.323013];
CLLocation *location2 = [[CLLocation alloc] initWithLatitude:60.050043 longitude:30.345783];

float betweenDistance=[location1 distanceFromLocation:location2];

NSLog(@"Distance is %f km",betweenDistance/1000);

Подскажите как мне вбить вместо координат location1 местоположение пользователя, что бы считать расстояние не от точки до точки, а от пользователя до точки?
