使用 CallKit 和 Twilio-Video API 触发传入的 VoIP 呼叫

Question

通过使用Twilio提供的示例视频通话应用程序之一（VideoCallKitQuickStart），我尝试通过向应用程序发送VoIP通知来触发来电。但该应用程序不会触发来电。我还尝试在发送VoIP通知时保持应用程序打开状态，并且应用程序崩溃，通过抛出以下异常

NSInvalidArgumentException： Try to 插入非属性列表对象"PKPushPayload： 0x16e44af0"作为键 有效载荷

有人可以，请帮助我或指出我在收到VoIP通知时如何在应用程序中触发来电的正确方向。

下面是我在ViewController.swift文件中的代码

 func pushRegistry(registry: PKPushRegistry!, didReceiveIncomingPushWithPayload payload: PKPushPayload!, forType type: String!) {
        // Process the received push
        self.reportIncomingCall(uuid: UUID(), roomName: "testRoom", completion: nil)
    } 
func reportIncomingCall(uuid: UUID, roomName: String?, completion: ((NSError?) -> Void)? = nil) {
    let callHandle = CXHandle(type: .generic, value: roomName ?? "")
    let callUpdate = CXCallUpdate()
    callUpdate.remoteHandle = callHandle
    callUpdate.supportsDTMF = false
    callUpdate.supportsHolding = true
    callUpdate.supportsGrouping = false
    callUpdate.supportsUngrouping = false
    callUpdate.hasVideo = true
    callKitProvider.reportNewIncomingCall(with: uuid, update: callUpdate) { error in
        if error == nil {
            NSLog("Incoming call successfully reported.")
        } else {
            NSLog("Failed to report incoming call successfully: (error?.localizedDescription).")
        }
        completion?(error as? NSError)
    }
}

发布延迟的答案，但可能对某人有所帮助。

按照我处理语音来电的代码。

func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) {
    NSLog("pushRegistry:didReceiveIncomingPushWithPayload:forType:")
    print(payload)
    if (type == PKPushType.voIP) {
        TwilioVoice.handleNotification(payload.dictionaryPayload, delegate: self)
        pushKitPushReceivedWithPayload(payload: payload)
    }
}
func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void) {
    NSLog("pushRegistry:didReceiveIncomingPushWithPayload:forType:completion:")
    if (type == PKPushType.voIP) {
        TwilioVoice.handleNotification(payload.dictionaryPayload, delegate: self)
        pushKitPushReceivedWithPayload(payload: payload)
    }
    completion()
}
func pushKitPushReceivedWithPayload(payload: PKPushPayload){
    if UIApplication.shared.applicationState != .active{
        let msgType = payload.dictionaryPayload["twi_message_type"] as? String
        if let messageType = msgType{
            if messageType == "twilio.voice.call"{
                fireLocalNotificationForVoiceCall(didStart: true)
            }else if messageType == "twilio.voice.cancel"{
                fireLocalNotificationForVoiceCall(didStart: false)
            }
        }
    }
}

以下是我添加的呼叫套件的代表方法

extension AppDelegate : TVONotificationDelegate, TVOCallDelegate
{
  func callInviteReceived(_ callInvite: TVOCallInvite) 
  {
   if (callInvite.state == .pending) 
   {
        //code
   } 
   else if (callInvite.state == .canceled) 
   {
        //code
   }
  }
  func handleCallInviteReceived(_ callInvite: TVOCallInvite) 
  {
        //code
  }
  func handleCallInviteCanceled(_ callInvite: TVOCallInvite) 
  {
        //code
  }
}

我遵循了twilio提供的本教程 - https://github.com/twilio/voice-quickstart-swift

完成本教程，它将起作用。

Twilio开发者布道者在这里。

我对iOS不是特别好，但是快速浏览一下文档，PKPushRegistryDelegate看起来您的pushRegistry函数定义不正确。

它应该是

func pushRegistry(_ registry: PKPushRegistry, 
    didReceiveIncomingPushWith payload: PKPushPayload, 
    forType type: PKPushType)

也就是说，didReceiveIncomingPushWith而不是didReceiveIncomingPushWithPayload.

或者，这与您将forType投给String这一事实有关吗？

Swift 3.0

func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, forType type: PKPushType) {
    NSLog("pushRegistry:didReceiveIncomingPushWithPayload:forType:")
    if (type == PKPushType.voIP) {
        print(payload.dictionaryPayload)
        VoiceClient.sharedInstance().handleNotification(payload.dictionaryPayload, delegate: self)
    }
}

并且请不要在未修改有效负载的情况下对有效负载进行任何更改，以便 SDK 从有效负载中提取传入呼叫信息，以便 SDK 可以将传入呼叫通知应用程序
