swift - iOS10下CLLocationManager不报初始位置(委托(delegate)函数未被调用)

Question

我有一个应用程序可以根据用户的位置显示一些数据。它在 Swift2 和 iOS9 上运行良好。现在没有调用 CLLocationManager 委托(delegate)的函数。 这是我的代码:

override func viewDidLoad() {
      super.viewDidLoad()
      locationManager.delegate = self //locationManager is being initialized at the top of class file and is not nil
       locationManager.requestAlwaysAuthorization()
       locationManager.desiredAccuracy = kCLLocationAccuracyKilometer
       locationManager.startUpdatingLocation() //This line executes from viewDidLoad, but not from delegate function
}


    func locationManager(_ manager: CLLocationManager, didDetermineState state: CLRegionState, for region: CLRegion) { //This is never called
            if CLLocationManager.authorizationStatus() != .authorizedWhenInUse {
                locationManager.requestWhenInUseAuthorization()
            }else{
                locationManager.startUpdatingLocation()
            }
        }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { //This is never called
        if updatingLocation == true { 
     //if location is updating, go next step
 }
}

我在我的 Info.plist 中启用了 Privacy - Location Always Usage Description 和 Privacy - Location When In Use Usage Description。为了测试我的代码，我还尝试调用 requestLocation，它也应该启动 didUpdateLocations，但它没有。也许我遗漏了一些东西，但对于 iOS10 的 CLLocationManager 处理似乎没有任何改变。

更新:更多代码

class HomeViewController: BaseViewController, CLLocationManagerDelegate {
var locationManager = CLLocationManager()
var updatingLocation = true
//other stuff
}

Answer 1

从 viewDidLoad() 中取出所有 locationManager 委托(delegate)函数:

override func viewDidLoad() {
    super.viewDidLoad()
    locationManager.delegate = self //locationManager is being initialized at the top of class file and is not nil
    locationManager.requestAlwaysAuthorization()
    locationManager.desiredAccuracy = kCLLocationAccuracyKilometer
    locationManager.startUpdatingLocation()
}

func locationManager(_ manager: CLLocationManager, didDetermineState state: CLRegionState, for region: CLRegion) { 
    ...
}

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

同时实现:

func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
    print("Failed: \(error.localizedDescription)")
}
