我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，我在所有位置都获得了很长的信息列表。以下是我用于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lat和long所以我可以保存它。输出结果为：

您正在使用println获取数据的文本转储。 CLPlaceMark是一种数据结构。
将此代码添加到您的闭包代码中，您已完成设置：
latitude = placemark.location.coordinate.latitude;
longitude = placemark.location.coordinate.longitude;
检查排序顺序。您可能希望选择第一个和最后一个元素，并确定是否通过增加或减少置信度排序来对其进行排序。 placemark [placemark.count -1]将为您提供最后一个元素。
