GeoCoder 使用地址获取经度和纬度

Question

我正在尝试使用地理编码器从地址中提取纬度和经度。不幸的是，当我运行下面的代码时，我得到了一个非常长的苹果商店所有位置的信息列表。下面是我用来打印展示位置的代码。

geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [AnyObject]!, error: NSError!) -> Void in
            if let placemark = placemarks?[0] as? CLPlacemark {
               println(placemark)
            }
            })

我只想要纬度和经度，这样我就可以保存它。输出结果为：

您正在获取数据的文本转储，因为您正在使用 println。 CLPlaceMark 是一个数据结构。

将此代码添加到您的关闭代码中，一切就绪：

latitude = placemark.location.coordinate.latitude;
longitude = placemark.location.coordinate.longitude;

检查排序。您可能想要选择第一个和最后一个元素，并确定这是按递增还是递减置信度顺序排序的。 placemark[placemark.count -1] 将为您提供最后一个元素。
