未获得用户位置

Question

我需要获取用户的位置。

我已经在info.plist中包含了所有三个键

在视图控制器中，我已经声明了变量：

       // Used to start getting the users location
var locationManager = CLLocationManager()
var currentLocation: CLLocation!

我用CLLocationManagerDelegate扩展了视图控制器

class HomeViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout, UISearchBarDelegate, CLLocationManagerDelegate

而且我已经将这段代码包含在viewDidLoad中：

  locationManager.requestWhenInUseAuthorization()


    if (CLLocationManager.authorizationStatus() == CLAuthorizationStatus.authorizedWhenInUse) || (CLLocationManager.authorizationStatus() == CLAuthorizationStatus.authorizedAlways) {

                currentLocation = locationManager.location
                print(currentLocation.coordinate.latitude)
                print(currentLocation.coordinate.longitude)

            }

要求用户授予许可，但未收到坐标。

我在做什么错？

您必须调用startupdatinglocation（）https://developer.apple.com/documentation/corelocation/cllocationmanager/1423750-startupdatinglocation才能接收CLLocationManagerDelegate的消息
