根据GPS数据获得国家名、城市名
1 Android：
利用google map api
Address
public String getCountryCode ()
Returns the country code of the address, for example "US", or null if it is unknown.
public String getCountryName ()
Returns the localized country name of the address, for example "Iceland", or null if it is unknown.

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。
