Question

我有这段代码：

override func viewDidLoad() {
    super.viewDidLoad()

    locationManager.delegate = self
    locationManager.requestWhenInUseAuthorization()
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.startUpdatingLocation()

}

和这段代码：

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let userLocation = locations.last
    print(userLocation)
    let camera = GMSCameraPosition.cameraWithLatitude(userLocation!.coordinate.latitude,
                                                      longitude: userLocation!.coordinate.longitude, zoom: 12.5)

    self.mapView.camera = camera
    self.mapView.myLocationEnabled = true
    // self.mapView.settings.myLocationButton = true

    locationManager.stopUpdatingLocation()
}

这比较早，但现在似乎没有调用locationManager，因为print语句根本没有返回任何信息。代码中没有错误，我似乎无法弄清楚为什么函数没有被调用。任何人都可以发现任何我不知道的明显事物吗？

谢谢

我刚刚实施了这个，我会告诉你我做了什么

首先，创建一个locationManager变量

let locationManager: CLLocationManager = CLLocationManager()

您必须在viewDidLoad()

中申请权限

viewMap.delegate = self
locationManager.delegate = self as? CLLocationManagerDelegate
locationManager.requestWhenInUseAuthorization()

然后，我创建了一个扩展，并实现了委托

extension MyView: CLLocationManagerDelegate {

  func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
   //here you configure the locationManager

  locationManager.startUpdatingLocation()

    viewMap.isMyLocationEnabled = true
    viewMap.settings.myLocationButton = true
}

  func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    }

}

我希望这对你有帮助，这里运作正常。
