其实问题是第一个实例没有收到来电。 我检查了 quickblox 的 github 上的视频聊天示例。它适用于我的用户/密码，所以我的代码有错误，但我真的不知道应该在哪里搜索。
如您所见，两个实例都有相同的问题：“远程对等方关闭了套接字”。但是这个问题发生在调用超时之后，所以它不是主要问题的原因。
【问题讨论】：
【参考方案1】：我终于找到了解决方案。问题出在 QBVideoChat 对象中。我认为当另一个用户呼叫我时 QBChat 会向我发送信号，然后我将创建 QBVideoChat 对象并在屏幕上显示它的视图。
可悲的事实是，在我创建 QBVideoChat 之前，QBChat 不会发送任何视频关系信号。所以我必须在程序开始时创建它才能接收 chatDidReceiveCallRequestFromUser 信号。
【讨论】：
好的。那你是怎么解决的？我遇到了同样的问题。检查 2 天 我在程序启动时创建了一个 QBVideoChat 对象。 _videoChat = [[QBChat 实例] createAndRegisterVideoChatInstance];以上是关于QuickBlox Chat：无法进行视频通话的主要内容，如果未能解决你的问题，请参考以下文章
