如何立即停止在文本字段中自动填充地址？

如何解决如何立即停止在文本字段中自动填充地址？

我已在info.plist中添加了三个权限

和弹出窗口带有三个选项。..

1）如果我单击"allow while using app"，则需要使用当前位置地址自动填充文本字段，但是

1. 如果我点击"allow once"，则不需要使用当前位置自动填充文本字段

在我的代码中，“允许一次”和“在使用条件时允许”两个文本字段均使用当前位置地址自动填充：

 class MapViewController: UIViewController,CLLocationManagerDelegate {

let locationManager = CLLocationManager()
var latitude: String?
var logitude: String?
@IBOutlet weak var text1: UITextField!
@IBOutlet weak var text2: UITextField!
@IBOutlet weak var text3: UITextField!
let annotation = MKPointAnnotation()

@IBOutlet weak var mapView: MKMapView!
override func viewDidLoad() {
    super.viewDidLoad()
    self.locationManager.requestAlwaysAuthorization()

    if CLLocationManager.locationServicesEnabled() {
        locationManager.delegate = self

        locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
        locationManager.startUpdatingLocation()
    }
}

func locationManager(_ manager: CLLocationManager,didUpdateLocations locations: [CLLocation]) {
    guard let _: CLLocationCoordinate2D = manager.location?.coordinate else { return }
    
    let userLocation :CLLocation = locations[0] as CLLocation
    latitude = "\(userLocation.coordinate.latitude)"
    logitude = "\(userLocation.coordinate.longitude)"
    let geocoder = CLGeocoder()
    geocoder.reverseGeocodeLocation(userLocation) { (placemarks,error) in
        if (error != nil){
            print("error in reverseGeocode")
        }
        let placemark = placemarks! as [CLPlacemark]
       
        if placemark.count>0{
            let placemark = placemarks![0]
          
            let placemarkDictonary: NSDictionary=placemark.addressDictionary as! NSDictionary
            self.text1.text=placemarkDictonary["ZIP"] as? String
            self.text2.text=placemarkDictonary["City"] as? String
            self.text3.text=placemarkDictonary["Street"] as? String
        }
    }
    
    let center = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude,longitude: userLocation.coordinate.longitude)
    let region = MKCoordinateRegion(center: center,span: MKCoordinateSpan(latitudeDelta: 0.1,longitudeDelta: 0.1))
    mapView.setRegion(region,animated: true)
    // Drop a pin at user's Current Location
    let myAnnotation: MKPointAnnotation = MKPointAnnotation()
    myAnnotation.coordinate = CLLocationCoordinate2DMake(userLocation.coordinate.latitude,userLocation.coordinate.longitude);
    myAnnotation.title = "Current location"
    mapView.addAnnotation(myAnnotation)
    locationManager.stopUpdatingLocation()
}

func locationManager(_ manager: CLLocationManager,didChangeAuthorization status: CLAuthorizationStatus) {
          switch status {
         
          case .denied:
              print("User hates you")

          case .authorizedWhenInUse:
              
               let viewController = self.storyboard?.instantiateViewController(withIdentifier: "FinalViewController") as! FinalViewController
               self.navigationController?.pushViewController(viewController,animated: true);

          case .authorizedAlways:
              
              let viewController = self.storyboard?.instantiateViewController(withIdentifier: "FinalViewController") as! FinalViewController
              self.navigationController?.pushViewController(viewController,animated: true);

          }
      }

@IBAction func contiBtn(_ sender: Any) {
}
}

实际上，当我单击"allow once"时，我仅需要当前位置坐标，而无需在文本字段中自动填充地址。该怎么做？

请提供代码帮助。
