最近公司项目闲下来，业余时间自己写了个请求封装类（OC / SWIFT），供大家参考，有不好的地方请大家见谅。
- tableview刷新控件cocopod集成
一、先给大家介绍一下OC VNHttpRequestManager 封装类
cocopods集成
https://github.com/guohongqi-china/VNHttpRequest
此类包含以下特点：
- 丰富的请求类型。常用请求类型，除了get、post 之外还支持 put、delete、patch、head等请求方式。
- 全面的参数提交类型。正常情况下，form 表单提交参数方式，我们大多数使用在文件交互方面；但是极少数情况下我们可能会使用到 form 表单 进行数据交互；此时如果提交方式不匹配，可能会存在接口不通或者接口通了，但是返回的数据状态不正确。
- 上传文件优化。批次上传图片，并对较大的图片做压缩优化；视频、音频也支持多批次。
- 支持断点下载文件。
- 丰富的错误信息采集。ServerResponseInfo 类采集了 http 响应码(响应码对应状态提示)、AFNet 响应码(响应码对应状态提示)、响应头信息。有些接口请求ResponseBody是不返回信息的，而是通过ResponseHeaders返回。
- 日志中的 Unicode 编码优化。某些情况，我们从后台获取的数据打印日志为Unicode编码，此类做了日志转码优化操作，使我们更能清晰的看到响应内容。
对于某些特殊的请求需要设置 请求头,或者请求超时时间(默认超时时间 10 s) 可在 + (void)requestSerializerSetting:(AFHTTPRequestSerializer *)requestSerializer；.m 文件方法中设置
