AFNetworking 2.0 相比1.0 API 接口改动还是很大的. 其中一个便是 AFURLSessionManager,当然如果你不太熟悉,或者为了兼容低版本,你依然可以选择AFHTTPRequestOperationManager,AFURLSessionManager是基于
NSURLSessionConfiguration(IOS 7.0+, MAC OX10_9+)的.
下面我们借用TuneStore的API 来完成AFURLSessionManager的讲解.
如果您在看这边文章之前 我建议您首先阅读下AFNetworking2.0的官方新特性介绍.
- AFNetworking 2.0 Migration Guide - 你如果之前用过AF1.0 这个是很有必要来看的.
- AFNetworking 2.0 Docs
- AFNetworking 2.0 Source
另外T*witer 上说NSHipster的AFNetworking现在翻译成中文了,所以我搬过来了有兴趣的朋友也可以去看下,https://github.com/NSHipster/articles/blob/zh-Hans/2013-09-16-afnetworking-2.md
