如何获得经度和纬度，然后将其存储在变量上？斯威夫特论

Question

因此，我尝试制作一个程序来检索用户的位置，这一次我想获取该区域中的纬度和经度，但是如何检索它们并将它们存储在一个变量中

import SwiftUI
import MapKit
import CoreLocationUI

struct ContentView: View {
  @StateObject private var viewModel = ContentViewModel()
    @State var LongStorage : Int = 0
    @State var LangStorage : Int = 0
    var body: some View {
        ZStack(alignment: .bottom){
            Map(coordinateRegion: $viewModel.region, showsUserLocation: true)
                .ignoresSafeArea()
                .tint(Color("GreenColor"))
            
            
            LocationButton(.currentLocation){
                viewModel.requestAllowOnceLocationPermission()
            }
            .foregroundColor(.white )
            .cornerRadius(10)
            .labelStyle(.titleAndIcon)
            .symbolVariant(.fill)
            .tint(Color("GreenColor"))
            .padding(.bottom, 50)
            
            
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

final class ContentViewModel: NSObject, ObservableObject, CLLocationManagerDelegate{
    
    @Published var region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude:  40, longitude: 120), span: MKCoordinateSpan(latitudeDelta: 100, longitudeDelta: 100))
    
    let locationManager = CLLocationManager()
    
    override init() {
        super.init()
        locationManager.delegate = self
    }
    
    func requestAllowOnceLocationPermission()  {
        locationManager.requestLocation()
    }
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        guard let latestLocation = locations.first else{
            //Show an error
            return
        }
        DispatchQueue.main.async {
            self.region = MKCoordinateRegion(center: latestLocation.coordinate, span: MKCoordinateSpan(latitudeDelta: 0.015, longitudeDelta: 0.015))
//check region value
            print("Region --> \(self.region)")
        }
    }
    
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print(error.localizedDescription)
    }
}

这就是终点站的结果，我怎么才能得到经纬度？

Region --> MKCoordinateRegion(center: __C.CLLocationCoordinate2D(latitude: 37.33036067, longitude: -122.02845007), span: __C.MKCoordinateSpan(latitudeDelta: 0.015, longitudeDelta: 0.015))

Answer 1

您已经获得了最新位置的值，所以只需将它们赋值给变量：

var latitude = region.center.latitude
var logitude = region.center.longitude

对我来说很难测试，因为不能只是复制粘贴您的代码来尝试它。
