如果我使用MKMapCamera，指南针不会在MKMapView上工作

Question

所以我想做三件事。

1. 有一张显示我所在位置的地图。
2. 地图应略微倾斜以给出3D感觉;就像我们在苹果地图上用两根手指向上和向下滚动一样。
3. 使用指南针旋转地图。

我已在地图上启用了userTrackingMode，地图会随着指南针一起旋转，但如果我在地图上设置了MKMapCamera，罗盘就无法工作。

这是我的代码。

    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")

        }

我在这里做错了什么？

您必须使用指南针更新摄像机的标题。这是我目前正在使用的东西：

func locationManager(_ manager: CLLocationManager, didUpdateHeading newHeading: CLHeading) {
        self.mapView.camera.heading = newHeading.trueHeading
}
