MonoTouch 获取位置&捕获地图图像（例如联系人）

Question

正如标题，我对如何使用 MonoTouch 捕获地图以及如何获取位置感到困惑。一步一步：

CLLocationManager locationManager = new CLLocationManager ();
locationManager.UpdatedLocation += UpdatedLocationEvent;
locationManager.Delegate = new MyLocationDelegate ();

locationManager.StartUpdatingLocation ();

    class MyLocationDelegate : CLLocationManagerDelegate
{
    public MyLocationDelegate () : base()
    {
    }

    public override void UpdatedLocation (CLLocationManager manager, CLLocation newLocation, CLLocation oldLocation)
    {
        Console.WriteLine ("newLocation  " + newLocation.VerticalAccuracy + "    " + newLocation.HorizontalAccuracy);
        Console.WriteLine ("oldLocation  " + oldLocation.VerticalAccuracy + "    " + oldLocation.HorizontalAccuracy);
    }

    public override void Failed (CLLocationManager manager, NSError error)
    {
        Console.WriteLine ("Failed to find location");
    }
}

它不起作用。请帮我。

您还没有配置获得的事件类型，您缺少这样的行：

locationManager = new CLLocationManager () {
    DesiredAccuracy = CLLocation.AccuracyBest,
    Delegate = new MyCLLocationManagerDelegate (callback),
    DistanceFilter = 1000f
};
if (CLLocationManager.LocationServicesEnabled)
    locationManager.StartUpdatingLocation ();
