我正在尝试将地图添加到我的应用程序，但我看到的只是黑屏......为什么？

Question

我试图显示地图并在地图中为用户提供位置，但我得到的只是黑屏。我觉得我设置正确但它不适合我。有没有人在我的代码中看到不正确的东西或我忘记添加的东西？这是代码：

class MapScene: SKScene, CLLocationManagerDelegate, MKMapViewDelegate {

var locationMangaer = CLLocationManager()
var map : MKMapView! = MKMapView()


override func didMoveToView(view: SKView) {
    locationMangaer.delegate = self
    locationMangaer.desiredAccuracy = kCLLocationAccuracyBest
    locationMangaer.requestWhenInUseAuthorization()
    locationMangaer.startUpdatingLocation()
    locationMangaer.requestAlwaysAuthorization()

    map.showsUserLocation = true
    map.delegate = self
    map.showsBuildings = true
    map.showsPointsOfInterest = true
    map.zoomEnabled = true
    map.scrollEnabled = true
    map.zoomEnabled = true
    map.rotateEnabled = true
    map.mapType = MKMapType.Hybrid
    map.pitchEnabled = false
    map.userInteractionEnabled = true


}



//DELEGATE METHODS

func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
    println(error)
}

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {


    var userLocation: CLLocation = locations[0] as! CLLocation
    locationMangaer.stopUpdatingLocation()

    let location = CLLocationCoordinate2DMake(userLocation.coordinate.latitude, userLocation.coordinate.longitude)
    let span = MKCoordinateSpanMake(0.05, 0.05)
    let region = MKCoordinateRegion(center: location, span: span)

    self.map.setRegion(region, animated: true)


    println("call")
}

我让它工作....我必须添加这两行代码：

    map.frame = CGRectMake(0, 0, frame.size.width, frame.size.height - 50)
    self.view?.addSubview(map)
