ios - RTCDataChannel iOS 不工作

Question

我正在使用 RTCDataChannel。但是我通过 channel 发送的消息在另一个对等端没有收到。

代码如下:

        let audioConstraint : RTCPair = RTCPair(key: "OfferToReceiveAudio", value: "true")
        let videoConstraint : RTCPair = RTCPair(key: "OfferToReceiveVideo", value: "true")
        let dtlsConstraint : RTCPair = RTCPair(key: "DtlsSrtpKeyAgreement", value: "true")
        let mediaContraints : RTCMediaConstraints = RTCMediaConstraints(mandatoryConstraints: [audioConstraint, videoConstraint], optionalConstraints: [ dtlsConstraint])

        RTCPeerConnectionFactory.initializeSSL()
        peerConnection = peerConnectionFactory.peerConnectionWithICEServers(servers, constraints: mediaContraints, delegate: self)

        dataChannels = peerConnection?.createDataChannelWithLabel(channelName,config: nil)
        dataChannels?.delegate = self


        var message : NSData = NSData(base64EncodedString: "helloo")
        var buffer : RTCDataBuffer = RTCDataBuffer(data: message, isBinary: true)
        dataChannels?.sendData(buffer)

你解决了吗？两个对等点之一应该创建数据通道，另一个应该将接收到的数据通道对象附加到它的数据通道对象。发起者应在发送报价之前创建数据通道。希望这可能会有所帮助
