Swift 即使IBOutlet已连接，远程视频流也不会呈现到UIView

我似乎无法将远程视频流正确渲染到我的UIView。我可以听到两个参与者的声音，但即使IO启动，似乎也无法渲染视频流

你知道为什么吗？这是我的密码：

func rtcEngine(_ engine: AgoraRtcEngineKit, firstRemoteVideoDecodedOfUid uid:UInt, size:CGSize, elapsed:Int) {

    DispatchQueue.main.async {

        if (self.remoteVideo.isHidden) {
            self.remoteVideo.isHidden = false
        }

        self.agoraKit.muteLocalAudioStream(false)

        let videoCanvas = AgoraRtcVideoCanvas()
        videoCanvas.uid = 0
        videoCanvas.view = self.remoteVideo
        videoCanvas.renderMode = .adaptive
        self.agoraKit.setupRemoteVideo(videoCanvas)

    }
}

从您的代码中，我看到您正在将UID分配为0。这意味着它将自动为远程视图生成新的UID。如果愿意，可以将UID设置为0以自动生成本地视频流但是对于远程流，您需要获取分配给远程流的UID，该UID作为UID变量提供在回调方法的参数中

此外，还需要确保在采用AgorartEngineedElegate协议的扩展中添加委托方法

extension VideoChatViewController: AgoraRtcEngineDelegate {
// Tutorial Step 5

    func rtcEngine(_ engine: AgoraRtcEngineKit, firstRemoteVideoDecodedOfUid uid:UInt, size:CGSize, elapsed:Int) {
        DispatchQueue.main.async {
            if (self.remoteVideo.isHidden) {
                self.remoteVideo.isHidden = false
            }
            self.agoraKit.muteLocalAudioStream(false)

            let videoCanvas = AgoraRtcVideoCanvas()
            videoCanvas.uid = uid
            videoCanvas.view = self.remoteVideo
            videoCanvas.renderMode = .adaptive
            self.agoraKit.setupRemoteVideo(videoCanvas)
        }
    }
}
