实时动态实现省市区三级联动选择器

实时动态实现省市区三级联动选择器

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。 我们需要对获取的后台三级链表数据进行排序和对象化后进行序列化。应用启动时进行反序列化。 结合​​​《省市区三级联动后台接口调用与数据预处理》​​​和​​《省市区三级联动数据本地序列化和反序列化》​​​。来实现省市区三级联动选择器。 BGChinaAddressModel.h
