推荐答案

来自自述文件：

据说，防止以下错误确保两件事

With that being said, to prevent the following error make sure of two things

1. 包含JSONKit / SBJson / YAJL


2. 您的部署目标低于iOS5，那样 AFNetworking 会意识到它无法使用 NSJSONSerialization 并且将会回到其中一个包含的JSON解析类。

1. that JSONKit / SBJson / YAJL are included
2. That your "Deployment Target" is lower than iOS5 , that way AFNetworking would realize it can't use NSJSONSerialization and will fall back to one of the included JSON parsing classes.

Shai。
