使用 AFNetworking 进行 XML 和 JSON 数据请求
（1）XML 数据请求
使用 AFNetworking 中的 AFHTTPRequestOperation 和 AFXMLParserResponseSerializer，另外结合第三方框架 XMLDictionary 进行数据转换
使用 XMLDictionary 的好处：有效避免自行实现 NSXMLParserDelegate 委托代理协议方法来进行繁琐的数据拼凑解析
（2）JSON 数据请求
使用 AFNetworking 中的 AFHTTPRequestOperation 或 AFHTTPRequestOperationManager，另外在图片缓存方面可选的方案有：
-
使用 AFNetworking 中 的 UIImageView+AFNetworking
-
使用第三方框架 SDWebImage 的 UIImageView+WebCache
效果如下：
