对服务器返回数据的解析
1.AFN可以自动对服务器返回的数据进行解析* 默认将服务器返回的数据当做JSON来解析
2.设置对服务器返回数据的解析方式
1> 当做是JSON来解析（默认做法）
*mgr.responseSerializer = [AFJSONResponseSerializer serializer];
*responseObject
的类型是NSDictionary
或者NSArray
2> 当做是xml来解析
*mgr.responseSerializer = [AFXMLParserResponseSerializer serializer];
*responseObject
的类型是NSXMLParser
3> 直接返回data* 意思是：告诉AFN不要去解析服务器返回的数据，保持原来的data即可
*mgr.responseSerializer = [AFHTTPResponseSerializer serializer];
AFNetworking请求 get与post
1. AFHTTPRequestOperationManager * mager=[AFHTTPRequestOperationManager manager];
mager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html”];
