1. AFN一套网络操作的第三方框架
a. NSURLConnection iOS2.0之后就有
b. NSURLSession iOS7.0之后才有
c. 默认支持序列化和反序列化json,xml需要自己解析 d. 优秀的错误处理机制
e. 封装了Reachability
f. 支持https
AFHTTPRequestOperationManager初始化的方法
○ self.requestSerializer = [AFHTTPRequestSerializer serializer];请求数据的序列化
○ self.responseSerializer = [AFJSONResponseSerializer serializer]; 返回数据的序列化
• <AFURLRequestSerialization>
发送给服务器的数据
二进制(默认)
json
plist 从服务器接收的数据
○ AFHTTPRequestSerializer
○ AFJSONRequestSerializer
○ AFPropertyListRequestSerializer
<AFURLResponseSerialization>
○ AFHTTPResponseSerializer
○ AFJSONResponseSerializer
○ AFXMLParserResponseSerializer
○ AFXMLDocumentResponseSerializer ○ AFPropertyListResponseSerializer ○ AFImageResponseSerializer
○ AFCompoundResponseSerializer
