使用扩展名将用户位置存储在可用变量中

如何解决使用扩展名将用户位置存储在可用变量中

我有一个扩展名，该扩展名是使用LocationManager创建的，用于将用户位置存储在要在Swiftui Map()和我的扩展名中使用的变量中。我注意到，当我初始化变量时，扩展名需要同时使用lat和long，而我只需要userLat即可。

latitude: userLocation.init(userLat: <#Double#>,userLong: <#Double#>).self.userLat,

   struct ContentView_v2: View {
    
    //    MARK: Get current location
        class userLocation {
            let locationManager = LocationManager()
    
            var userLat: Double
            var userLong: Double
    
            init(userLat: Double,userLong: Double){
                self.userLat = locationManager.lastLocation?.coordinate.latitude ?? 0.0
                self.userLong = locationManager.lastLocation?.coordinate.longitude ?? 0.0
            }
    
        }
    
        @State private var region = MKCoordinateRegion(
            center: CLLocationCoordinate2D(
                latitude: userLocation.init(userLat: <#Double#>,longitude: userLocation.init(userLat: <#Double#>,userLong: <#Double#>).self.userLong
            ),span: MKCoordinateSpan(
                latitudeDelta: 0.01,longitudeDelta: 0.01
                )
        )
var body: some View {
        Map(
            coordinateRegion: $region,interactionModes: MapInteractionModes.all,showsUserLocation: true,userTrackingMode: $userTrackingMode,annotationItems: yelpbusinessmapdata?.businesses ?? []
        )
        { business in
            MapAnnotation(
                coordinate:
                    business.coordinates.coordinate2D,anchorPoint: CGPoint(x: 0.5,y: 0.5)
            ){
                vstack {
                    Image(systemName: "mappin")
                        .font(.system(size: 18,weight: .medium))
                        .foregroundColor(.red)
                    Text(business.name)
                }
                

            }
        }

解决方法

如果我正确理解了您的代码，则可能您需要以下内容...

    class userLocation {
        let locationManager = LocationManager()

        var userLat: Double
        var userLong: Double

        init(){
            self.userLat = locationManager.lastLocation?.coordinate.latitude ?? 0.0
            self.userLong = locationManager.lastLocation?.coordinate.longitude ?? 0.0
        }

    }

    @State private var region = MKCoordinateRegion(
        center: CLLocationCoordinate2D(
            latitude: userLocation().userLat,longitude: userLocation().userLong
        ),
