现在我正在使用google webRTC（会议）iOS应用并使用socket.io作为信令协议。
对于用户之间信令的个别管理，我需要为每个客户端创建套接字。
在第一个客户端，我创建了两个频道，一个是公共的（用于公共广播的消息），一个是我自己的私有（使用我的id作为命名空间）。请参阅 - “initChannel”和“createMyChannel”。
当新用户加入房间时，我在公共频道中获得'newParticipant'事件，使用新的用户ID我创建一个私人频道，将私人消息发送到该特定用户的频道，该频道已由该用户创建客户在他/她加入房间时。请参阅 - “WRTCSignalingType”切换案例。
一切正常，除非我收到'newParticipant'后发送消息给用户的私人频道，在接收方一侧多次调用处理器
[self.myChannel on:@"message" callback:^(NSArray * data, SocketAckEmitter * ack) {
NSLog(@"Data >>> %@", data);
}];
我不知道为什么会发生这种情况......是多次发送的消息或其他内容，或者是这个库的错误。
请帮助......这只会让我发疯。
