iOS开发之百度免费API使用案例（身份证号获取地址、手机号查归属地、MD5解密等）

本文链接：https://blog.youkuaiyun.com/l2i2j2/article/details/51649790

本文介绍如何利用百度APIStore提供的API接口进行多种类型的数据查询和服务调用，包括天气查询、身份证信息解析、生成二维码等功能，并提供了具体的iOS代码实现。

先附上百度APIStore的地址：APIStore

下面是其中几个使用案例：考虑到我的博客看的人比较少，里面的apikey就不隐藏了。万一有一天如果apikey使用频率过高被封了，请自行去百度APIStore申请

（身份证号码这俩，不太严谨，不能判断出生日期是否正确，只能解析出所在省市区，和判断最后一位校验码）
