问如果我使用MKMapView，罗盘就不能在MKMapCamera上工作

EN

    override func viewDidLoad() {
            super.viewDidLoad()
            // Do any additional setup after loading the view, typically from a nib.
            locationManager.desiredAccuracy = kCLLocationAccuracyBest
            locationManager.delegate = self
            locationManager.requestWhenInUseAuthorization()
            mapView.setUserTrackingMode(.FollowWithHeading, animated: true)
            locationManager.startUpdatingLocation()

        }


func locationManager(manager: CLLocationManager, didUpdateToLocation newLocation: CLLocation, fromLocation oldLocation: CLLocation) {


            let userCordinate = CLLocationCoordinate2D(latitude: newLocation.coordinate.latitude, longitude: newLocation.coordinate.longitude)

            let eyeCordinate = CLLocationCoordinate2D(latitude: newLocation.coordinate.latitude - 0.021078, longitude: newLocation.coordinate.longitude - 0.04078 )



            let mapCamera = MKMapCamera(lookingAtCenterCoordinate: userCordinate, fromEyeCoordinate: eyeCordinate, eyeAltitude: 1400)

            mapView.setCamera(mapCamera, animated: true)
            print("Camera set")

        }
