您缺少两件事。首先，您必须使用requestAlwaysAuthorization或寻求许可requestWhenInUseAuthorization()。所以你viewDidLoad()应该是这样的：
var locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
其次，Info.plist 按照此处的指示编辑您的。
