ios - AFNetworking - 流 0x96c93c0 在打开之前发送事件

Question

我正在尝试将一些数据发送到AFNetworking到我的服务器，但是当我想发送数据时，控制台日志中出现以下错误，并且服务器从未收到数据。

有谁知道我为什么会收到此错误？

2013-06-06 17:02:16.246 iGym[15255:c07] Stream 0xa267930 is sending an event before being opened

更新:看起来像this accepted pull request应该可以解决你的问题。更新 AFNetworking，并完成您的构造函数 block 。

<小时/>

1. 您需要在构造函数 block 中放置一些代码；看来你的被注释掉了。

2. 有一个 open issue related to this在 AFNetworking GitHub 网站上(它已经存在了大约一个月)。已经应用了一些补丁，但看起来并没有 100% 解决。您可能需要确保使用的是最新版本的 AFNetworking。
