AFNetworking是一個輕量級的iOS網絡通信類庫。它建立在NSURLConnection和NSOperation等類庫的基礎上。它支援HTTP請求和基于REST的網絡服務（包括GET、POST、 PUT、DELETE等）。支援ARC。

/**
要使用正常的AFN網絡通路
1. AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
所有的網絡請求,均有manager發起
2. 需要注意的是,預設送出請求的資料是二進制的,傳回格式是JSON
1> 如果送出資料是JSON的,需要将請求格式設定為AFJSONRequestSerializer
2> 如果傳回格式不是JSON的,
3. 請求格式
AFHTTPRequestSerializer 二進制格式
AFJSONRequestSerializer JSON
AFPropertyListRequestSerializer PList(是一種特殊的XML,解析起來相對容易)
4. 傳回格式
AFHTTPResponseSerializer 二進制格式
AFJSONResponseSerializer JSON
AFXMLParserResponseSerializer XML,隻能傳回XMLParser,還需要自己通過代理方法解析
AFXMLDocumentResponseSerializer (Mac OS X)
AFPropertyListResponseSerializer PList
AFImageResponseSerializer Image
AFCompoundResponseSerializer 組合
