GeoCoder 使用地址获取经度和纬度

【中文标题】GeoCoder 使用地址获取经度和纬度【英文标题】：GeoCoder using address to get longitude and latitude 【发布时间】：2015-05-26 04:34:44 【问题描述】：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，我得到了所有位置的苹果商店信息列表。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)
)
我想要的只是纬度和经度，所以我可以保存它。输出结果为：

【问题讨论】：
【参考方案1】：您正在获取数据的文本转储，因为您使用的是 println。 CLPlaceMark 是一种数据结构。
将此代码添加到您的闭包代码中，一切就绪：
latitude = placemark.location.coordinate.latitude;
longitude = placemark.location.coordinate.longitude;
检查排序顺序。您可能想要选择第一个和最后一个元素，并确定这是按置信顺序递增还是递减排序。 placemark[placemark.count -1] 将为您提供最后一个元素。
