Objective c 纬度，从mapView.userLocation开始的经度

我有以下代码来获取我的应用程序上的用户位置：

mapView.showsUserLocation=TRUE;
    mapView.userLocation.title=@"Aktuelle Position";

这在

viewDidLoad（）中

但是，如何通过以下方法从
userLocation
获取纬度和长度

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation{

    Koordinate *user = mapView.userLocation;
    Koordinate *cord1 = [eventPoints objectAtIndex:2];
    CLLocation *loc1 = [[CLLocation alloc] initWithLatitude:cord1.latitude longitude:cord1.longtitude];

    Koordinate *cord2 = [eventPoints objectAtIndex:3];
    CLLocation *loc2 = [[CLLocation alloc] initWithLatitude:cord2.latitude longitude:cord2.longtitude];

    double distance = [loc1 getDistanceFrom:loc2] / 1000;

    NSLog(@"Distanz:", distance);
}

这是对我有用的东西

yourMapView.userLocation.location.coordinate.latitude;
yourMapView.userLocation.location.coordinate.longitude;

这是一本书。
yourMapView.userLocation.location.coordinate.latitude;
yourMapView.userLocation.location.coordinate.longitude;
