我正在使用 quickblox 开发视频聊天应用程序。而且我在进行视频通话时遇到了麻烦。有一次启动的两个应用程序实例的日志:

调用第一个实例的第二个实例:

实际上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它。

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呼叫超时之后,所以它不是主要问题的原因。

最后我找到了解决方案。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。
