斯威夫特，乘坐附近的用户位置的地方

Question

我在制定我加入我的应用程序的视图中的谷歌地图，下面的教程我用这个代码

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { 
      let location: CLLocation = locations.last! 
      print("Location: \(location)") 

      let camera = GMSCameraPosition.camera(withLatitude: location.coordinate.latitude, 
                longitude: location.coordinate.longitude, 
                zoom: zoomlevel) 


      let marker = GMSMarker() 
      marker.title = "My Position" 

      marker.map = mapView 
      if mapView.isHidden { 
       mapView.isHidden = false 
       mapView.camera = camera 
      } else { 
       mapView.animate(to: camera) 
      } 


     } 


     func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) { 
      switch status { 
      case .restricted: 
       print("Location access was restricted.") 
      case .denied: 
       print("User denied access to location.") 

       mapView.isHidden = false 
      case .notDetermined: 
       print("Location status not determined.") 
      case .authorizedAlways: fallthrough 
      case .authorizedWhenInUse: 
       print("Location status is OK.") 
      } 
     } 


     func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) { 
      locationManager.stopUpdatingLocation() 
      print("Error: \(error)") 
     } 

找到用户初学者位置，现在我想在地图上看到距用户位置X距离的地方（谷歌地点），我该如何做？我搜索了谷歌的地方文件，但没有找到有效的答案

Answer 1

在mapView上添加另一个标记onTap并使其可拖动并使用CLLocationDistance来测量2个位置之间的距离。

let distanceInMeters = self.locationManager.location?.distance(from: newMarkerLocation!)
