iOS基础8:自定义MyData/自定义SQLite用于网络判断,版本判断,图片缓存处理,下载或者上传的GET或POST请求,加密手段,.数据解析

镔哥,这篇文章是用自己的工程项目来的,主要是代码为主,但是会有注释,让大家能更好理解,让大家做工程更多一个选择,这其实就是自己自定义SQLite,不多说,见代码例子

MyDAta的.h文件

/*

 MyData这一个基本上每个工程都能用到的Demo,他包含了很多内容:

 1.iPhone机网络判断;

 2.iPhone机软件版本判断(主要是看是否是大于IOS7);

 3.图片缓存处理;

 4.下载或者上传的GETPOST请求;

 5.加密手段;

 6.数据解析;
