iphone ipad 显示当前城市名称

概述利用 iPhone、iPad 自带的 GPS 信息可以获得当前位置坐标，但直接高速用户坐标是不行的。CocoaChina 会员"laigb"分享了通过 GPS 信息获取当前所在城市名的代码，希望对苹果开发者有所帮助。 //  testLocationViewController.m //作者：禚来强 iphone开发*****：79190809 邮箱：zhuolaiqiang@gmail.com 利用 iPhone、iPad 自带的 GPS 信息可以获得当前位置坐标，但直接高速用户坐标是不行的。CocoaChina 会员"laigb"分享了通过 GPS 信息获取当前所在城市名的代码，希望对苹果开发者有所帮助。
