ios - 如何获取标注 c# xamarin 的 MKPlacemark 地址

Question

我正在尝试获取地址。到目前为止我所掌握的只是使用

获取坐标

 CLLocation loc = new CLLocation(anno.Coordinate.Latitude, anno.Coordinate.Longitude);

但是，我尝试了反向地理编码和地标。它们都不起作用。 以下示例尚未完成且格式不正确。我只是从 swift 复制过来。

 async void ReverseGeocodeToConsoleAsync(CLLocation location)
                {
                    var geoCoder = new CLGeocoder();
                    var placemarks = await 
                    geoCoder.ReverseGeocodeLocationAsync(location);
                    var placemark = placemarks[0] as CLPlacemark;
                    var addressString = "";
                    //String to hold address
                        var locatedAtcountry = placemark.country;
                        var locatedAtcity = placemark.locality;
                        var locatedAtisocountry = placemark.ISOcountryCode;
                if (placemark.ISOcountryCode == "TW") /*Address Format in Chinese*/
                {
                    if (placemark.country != null)
                    {
                        addressString = placemark.country!
                    }
                }

看来您的代码已接近成功。这是一个可以从位置获取地址的示例。

        public void GetAddress(CLLocation loc)
        {
            CLGeocoder ceo = new CLGeocoder();

            ceo.ReverseGeocodeLocation(loc, (placemarks, error) =>
            {
                CLPlacemark placemark = placemarks[0];
                if (placemark != null)
                {
                    Console.WriteLine(placemark.IsoCountryCode);
                    Console.WriteLine(placemark.Country);
                }
            });
        }
