Sinch iOS应用程序：识别应用程序是否接收视频或语音呼叫

我在sinch的swift项目中集成了视频通话和语音通话。但问题是，在

appDelegate

中，我有一个函数

didReceiveInMingCall

。如何在此函数中输入一些代码，以确定调用是语音调用以显示

voiceCallVC

还是视频调用以显示

VideoVC

  func client(_ client: SINCallClient!, didReceiveIncomingCall call: SINCall!) {


        var top = self.window?.rootViewController

        while (top?.presentedViewController != nil) {
            top = top?.presentedViewController
        }

        let videoVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "videoVC") as! VideoCallVC
        videoVC._call = call
        top?.present(videoVC, animated: true, completion: nil)

        let callVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "CallVC") as! VoiceCallVC
        callVC._call = call
        top?.present(callVC, animated: true, completion: nil)
    }

您可以检查Bool值

“call.details.isvideoprovided”

这是代码

    func client(_ client: SINCallClient!, didReceiveIncomingCall call: SINCall!) {

     var top = self.window?.rootViewController

     while (top?.presentedViewController != nil) {
        top = top?.presentedViewController
       }
        if (call.details.isVideoOffered)
        {
            let videoVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "videoVC") as! VideoCallVC
            videoVC._call = call
            top?.present(videoVC, animated: true, completion: nil)
        }
        else{
            let callVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "CallVC") as! VoiceCallVC
           callVC._call = call
           top?.present(callVC, animated: true, completion: nil)
        }

  }
