AFNetworking淺析
AFNetworking 是為iOS 和Mac OSX 制作的一個非常強大的網絡庫，它建立在URL裝載系統框架的頂層，內置在cocoa里，擴展了強有力的高級網絡抽象。它擁有良好的架構，豐富的功能設計。
AFNetworking功能梳理
AFURLConnectionOperation : 繼承自NSOperation 實現了NSURLConnection 的代理方法。
AFHTTPRequestOperation : 繼承自AFURLConnectionOperation的子類,當request請求使用的協議為HTTP和HTTPS時使用,它封裝了用于 決定request是否成功的狀態碼和內容類型。
AFJSONRequestOperation : 繼承自AFHTTPRequestOperation,用于下載和處理json response數據。
AFXMLRequestOperation : 繼承自 AFHTTPRequestOperation,用于下載和處理xml response數據。
AFPropertyListRequestOperation : 繼承自 AFHTTPRequestOperation,用于下載和處理 property list? response數據。
