（1）xml 數(shù)據(jù)請求
使用 AFNetworking 中的 AFHTTPRequestOperation 和 AFXMLParserResponseSerializer，另外結(jié)合第三方框架 XMLDictionary 進(jìn)行數(shù)據(jù)轉(zhuǎn)換
使用 XMLDictionary 的好處：有效避免自行實現(xiàn) NSXMLParserDelegate 委托代理協(xié)議方法來進(jìn)行繁瑣的數(shù)據(jù)拼湊解析
（2）JSON 數(shù)據(jù)請求
使用 AFNetworking 中的 AFHTTPRequestOperation 或 AFHTTPRequestOperationManager，另外在圖片緩存方面可選的方案有：
使用 AFNetworking 中 的 UIImageView+AFNetworking
使用第三方框架 SDWebImage 的 UIImageView+WebCache
效果如下：
