ios - 将纬度和经度放在 map View 上

Question

我试图通过插入纬度和经度在mapView中显示我想要的地方，但我失败了， map 总是显示我所在的位置，而不是我想要到达的地方

这些是我使用的代码

class MapViewController: UIViewController, CLLocationManagerDelegate{
    @IBOutlet weak var map: MKMapView!
    let manager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

        map.showsPointsOfInterest = true
        map.showsUserLocation = true
        manager.requestAlwaysAuthorization()
        manager.requestWhenInUseAuthorization()
        //user location stuff
        if CLLocationManager.locationServicesEnabled() {
            manager.delegate = self
            manager.desiredAccuracy = kCLLocationAccuracyBest
            manager.startUpdatingLocation()
        }
    }

    func locationManager(_manager: CLLocationManager, didUpdateLocations locations:[CLLocation]) {
        let span:MKCoordinateSpan = MKCoordinateSpanMake(0.01, 0.01)
        let location = CLLocationCoordinate2D(latitude: 36.1070, longitude: -112.1130)
        let region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)
        map.setRegion(region, animated: true)
        self.map.showsUserLocation = true
    }
}

map.showsUserLocation = true

并将didUpdateLocations的代码放入viewDidLoad

class MapViewController: UIViewController, CLLocationManagerDelegate{
    @IBOutlet weak var map: MKMapView!
    let manager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

        map.showsPointsOfInterest = true
        //map.showsUserLocation = true
        manager.requestAlwaysAuthorization()
        manager.requestWhenInUseAuthorization()
        //user location stuff
        if CLLocationManager.locationServicesEnabled() {
            manager.delegate = self
            manager.desiredAccuracy = kCLLocationAccuracyBest
            manager.startUpdatingLocation()
        }

        let span:MKCoordinateSpan = MKCoordinateSpanMake(0.01, 0.01)
        let location = CLLocationCoordinate2D(latitude: 36.1070, longitude: -112.1130)
        let region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)
        map.setRegion(region, animated: true)
    }

    func locationManager(_manager: CLLocationManager, didUpdateLocations locations:[CLLocation]) {
         ///
    }
}
