- 要使用常规的AFN网络访问
- 1. AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
- 所有的网络请求,均有manager发起
- 2. 需要注意的是,默认提交请求的数据是二进制的,返回格式是JSON
- 1> 如果提交数据是JSON的,需要将请求格式设置为AFJSONRequestSerializer
- 2> 如果返回格式不是JSON的,
- 3. 请求格式
- AFHTTPRequestSerializer 二进制格式
- AFJSONRequestSerializer JSON
- AFPropertyListRequestSerializer PList(是一种特殊的XML,解析起来相对容易)
- 4. 返回格式
- AFHTTPResponseSerializer 二进制格式
- AFJSONResponseSerializer JSON
- AFXMLParserResponseSerializer XML,只能返回XMLParser,还需要自己通过代理方法解析
- AFXMLDocumentResponseSerializer (Mac OS X)
- AFPropertyListResponseSerializer PList
- AFImageResponseSerializer Image
- AFCompoundResponseSerializer 组合
