QuickBlox WebRTC iOS：无法正常连接

标签： ios quickblox

我正在尝试使用QuickBlox-WebRTC创建一个带有视频聊天的iOS应用程序。

我的控制器是一个QBRTCClientDelegate，一切似乎都很“好”。命中以下调用（不按顺序）：

  • didReceiveNewSession
  • initializedLocalMediaStream
  • receivedRemoteVideoTrack
  • acceptedByUser

但遗憾的是，startedConnectingToUser和connectedToUser从未发生过。

在来电方面，我在日志中看到以下内容：

...它重复最后两行。

我已经检查了它在示例应用程序中是如何发生的，而且当发生以下情况时，我的应用程序似乎永远不会出现：

2016-02-09 12:48:49:006 sample-videochat-webrtc[278:20551] rtc::Did receive signal: iceCandidates from: 2436266

我在这里缺少什么？比较我的实现和样本，我没有注意到太多差异。

事实证明这是一个与语法相关的简单错误。在创建会话时，我使用过：

QBRTCSession *newSession = [QBRTCClient.instance
         createNewSessionWithOpponents:@[receipientStr] 
                    withConferenceType:QBRTCConferenceTypeVideo];

但正确的语法是

QBRTCSession *newSession = [QBRTCClient.instance 
         createNewSessionWithOpponents:@[@(receipientStr.intValue)]
                    withConferenceType:QBRTCConferenceTypeVideo];

通过此修改，视频现已完全正常工作。
