没有调用CLLocationManager委托方法（已集成Google地图）

Question

CLLocationManager的委托方法

didChangeAuthorizationStatus和didUpdateToLocation

没有接到电话。

位置始终使用说明键已添加到info.plist中，并且在我首次启动应用程序时也收到通知。

我能够看到谷歌地图，但是我看不到当前位置，当我更改位置时，它不会更新。基本上不会调用委托方法。

import UIKit
import GoogleMaps

class ViewController: UIViewController,GMSMapViewDelegate {
    @IBOutlet weak var mapViewTest: GMSMapView!
    let locationManager = CLLocationManager()
    var currentLocation :CLLocation = CLLocation(latitude: 0.0, longitude: 0.0)
    var currentLatitude : Double = 0.0
    var currentLongitude : Double = 0.0

        {

        locationManager.allowsBackgroundLocationUpdates = true
        locationManager.requestAlwaysAuthorization()
        locationManager.startUpdatingLocation()
        }
        // Do any additional setup after loading the view, typically from a nib.
    }

    {
       func locationManager(manager: CLLocationManager,     didChangeAuthorizationStatus status: CLAuthorizationStatus)
        {
            if status == .authorizedAlways
            {
                if(CLLocationManager .locationServicesEnabled())
                {

                    mapViewTest.settings.myLocationButton = true
                }
            }
        }
         func locationManager(manager: CLLocationManager, didUpdateToLocation newLocation: CLLocation, fromLocation oldLocation: CLLocation)
        {
            mapViewTest.camera = GMSCameraPosition(target: (newLocation.coordinate), zoom: 15, bearing: 0, viewingAngle: 0)
            currentLocation = newLocation
            currentLatitude = newLocation.coordinate.latitude
            currentLongitude = newLocation.coordinate.longitude

        }
        func locationManager(manager: CLLocationManager, didFailWithError error: NSError)
        {
            print("Errors: " + error.localizedDescription)
        }
    }

在您的代码中，您正在使用Swift 3，并且在Swift 3中，CLLocationManagerDelegate方法的签名是这样更改的。

func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {

}

//func locationManager(_ manager: CLLocationManager, didUpdateTo newLocation: CLLocation, 
       from oldLocation: CLLocation) is deprecated with below one
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

}

func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {

}
