Как " показать мое текущее местоположение на картах google, когда я открываю ViewController?- в Свифте?

используйте этот код,

пропустить addObserver метод и некоторое содержание,

viewDidLoad:

mapView.settings.compassButton = YES;

mapView.settings.myLocationButton = YES;

mapView.addObserver(self, forKeyPath: "myLocation", options: .New, context: nil)

dispatch_async(dispatch_get_main_queue(), ^{
    mapView.myLocationEnabled = YES;
  });

Метод Наблюдателя:

override func observeValueForKeyPath(keyPath: String, ofObject object: AnyObject, change: [NSObject : AnyObject], context: UnsafeMutablePointer<Void>) {

    if change[NSKeyValueChangeOldKey] == nil {

        let location = change[NSKeyValueChangeNewKey] as CLLocation
        gmsMap.camera = GMSCameraPosition.cameraWithTarget(location.coordinate, zoom: 16)
    }
}

надеюсь, что его полезным

• сначала добавьте следующую информацию.файл plist

  1. NSLocationWhenInUseUsageDescription
  2. LSApplicationQueriesSchemes (типа array и добавить два элемента в этот массив пункт 0 : googlechromes , пункт 1 : comgooglemaps

• во https://developers.google.com/maps/documentation/ios-sdk/start и следуйте инструкциям до шага 5

• последнее дело после того, как вы настроили все, чтобы перейти к вашему ViewController и вставить следующее

  import UIKit
  import GoogleMaps
  
  class ViewController: UIViewController,CLLocationManagerDelegate {
  
      //Outlets
      @IBOutlet var MapView: GMSMapView!
  
      //Variables
      var locationManager = CLLocationManager()
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          initializeTheLocationManager()
          self.MapView.isMyLocationEnabled = true
      }
  
      func initializeTheLocationManager() {
          locationManager.delegate = self
          locationManager.requestWhenInUseAuthorization()
          locationManager.startUpdatingLocation()
      }
  
      func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
  
          var location = locationManager.location?.coordinate
  
          cameraMoveToLocation(toLocation: location)
  
      }
  
      func cameraMoveToLocation(toLocation: CLLocationCoordinate2D?) {
          if toLocation != nil {
              MapView.camera = GMSCameraPosition.camera(withTarget: toLocation!, zoom: 15)
          }
      }
  
  }
  

(не забудьте добавить вид в раскадровку и подключить его к MapViw)

Теперь вы можете создавать и запускать, чтобы увидеть свое текущее местоположение на карте google так же, как при открытии приложения Google Map

наслаждайтесь кодирования :)
