如何根据用户行进的方向旋转地图（不面向相机）-Swift 5-iOS

Question

我已经在这里进行了研究，以尝试解决我的问题，但是我似乎找不到解决方案。我希望地图旋转，所以屏幕的顶部是用户的行进方向。下面的代码有效，但会根据手机所面对的方向旋转屏幕。我只希望地图在用户朝不同方向移动时旋转。

有人解决了这个问题吗？

  let manager = CLLocationManager()

   @IBOutlet weak var map: MKMapView!



    func locationManager(_ manager: CLLocationManager, didUpdateHeading newHeading: CLHeading){
    map.camera.heading = newHeading.magneticHeading
    map.setCamera(map.camera, animated: true)
    print("updatingHeading is called")
   }


func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {


    let location = locations[0]
    let span:MKCoordinateSpan = MKCoordinateSpan.init(latitudeDelta: 0.01,longitudeDelta: 0.01)
        let myLocation:CLLocationCoordinate2D = CLLocationCoordinate2DMake(location.coordinate.latitude,location.coordinate.longitude)
        let region:MKCoordinateRegion = MKCoordinateRegion.init(center: myLocation, span: span)
        map.setRegion(region, animated: true)
        self.map.showsUserLocation = true

        let mapCamera = MKMapCamera(lookingAtCenter: myLocation, fromDistance: 5000, pitch: 30, heading: 0)
        map.setCamera(mapCamera, animated: true)
 }




 func viewDidLoad() {
 manager.startUpdatingLocation()
 manager.startUpdatingHeading() 
}

swift中有什么可以帮助我的吗？
