使用 XMPP 的 iOS 连接到 ejabberd 失败

Question

我正在使用https://github.com/robbiehanson/XMPPFramework 连接到我自己的 ejabberd 服务器，但协商后总是失败。

检查此处报告的解决方案 https://github.com/robbiehanson/XMPPFramework/issues/131 是否解决了您的问题。

一般当服务器关闭连接时，你会得到这个 error/ 服务器关闭连接时的两个原因：

2. 您正在使用相同的凭据从某些不同的客户端登录，并且在服务器设置中有以下设置： 总是踢 - 如果有资源冲突，立即踢另一个资源。在服务器>服务器设置>资源策略。
