我正在为iOS 8开发一段Swift代码.我正在尝试做一些涉及位置的事情,所以我在我的swift视图控制器文件中实现了以下内容:

let locationManger:CLLocationManager = CLLocationManager()

var speedReceived:Double = 0

override func viewDidLoad() {
    super.viewDidLoad()
    locationManger.delegate = self
    locationManger.desiredAccuracy = kCLLocationAccuracyBest
    let authstate = CLLocationManager.authorizationStatus()
    if(authstate == CLAuthorizationStatus.NotDetermined){
       println("Not Authorised")  
      locationManger.requestWhenInUseAuthorization()
    }
    // Do any additional setup after loading the view, typically from a nib.
}

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!){
    var location:CLLocation = locations[locations.count - 1] as CLLocation
    if(location.horizontalAccuracy > 0){
        self.speedReceived = location.speed
        println(self.speedReceived)
    }
}

func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
   println("Couldn't get your location") …
