由于现在经常出现撤县建市，裁撤乡村，大城市把撤县设区以及区划调整，所以需要更新省市区的数据。
解决办法是后台从民政部获取官方省市区数据，录入数据库。后台增加接口让前端调用，获取实时省市区实时数据。
由于省市区数据超过4000条记录，数据量极大，这种实时获取的方式十分费时间和流量。所以要做本地化处理。
把省市区版本号存入系统plist文件([[NSUserDefaults standardUserDefaults] objectForKey:key])，应用启动时，判断版本号是否一致，若不一致清除本地数据，若一致加载本地化数据放入内存，以便于有获取省市区。
在使用的页面判断内存中是否有省市区数据，若没有就调用省市区接口并本地化数据。
当然你若认为把省市区本地化数据加载如内存浪费内存，也使用时获取就可以。一般的手机内存都很大，也不在乎那几百k的内存。
