iOS 13原因:“杀死app是因为它在收到PushKit VoIP推送回拨后从未向系统发布来电。”

Question

从很多天起，我就陷入了这个问题...

AnyHashable("aps"): {
    alert =     {
        action = test;
        body = "{\"action\":\"connect\",\"meetingId\":\"mdkdkkydjgedjhd\",\"from\":\"sender\",\"fromToken\":\"9d739e878521cf770d9e5136161cf7611c242ef2a8b53c83c81b6b6021a7b31b\",\"to\":\"receiver\",\"toToken\":\"e65bf5e3d6a3e440eb364fb620539de4f4c2c1bf98be5f753f5abfbe7fecea74\",\"callUUID\":\"9EB823F3-F857-490B-BCFC-373D05E56933\"}";
        title = Call;
    };
}]

这是我正在接收的有效载荷，并根据动作发出传入呼叫

func getPushkitPayload(payload : [AnyHashable : Any], completionOfHandlingIncomingCall : @escaping (Bool) -> Void){
    let dict : Dictionary <String, AnyObject> = payload["aps"] as! Dictionary<String, AnyObject>
    let Alert : Dictionary <String, AnyObject> = dict["alert"] as! Dictionary<String, AnyObject>
    let strBody : String = Alert["body"] as? String ?? ""

    if let data = strBody.data(using: String.Encoding.utf8) {
        do {
            let model = try JSONDecoder().decode(PushkitModel.self, from: data)
            print("RES MODEL")
            dump(model)
            //if app background
            if  UIApplication.shared.applicationState == .background || UIApplication.shared.applicationState == .inactive {
                //here check action if it is connect then show incoming call
                if model.action == "connect" {
                    CallKitManager.shared.receiveCall(model: model, delegate: self) { (initiated) in
                        completionOfHandlingIncomingCall(initiated)
                    }
                } else {
                    let sendModelToNotCenter:[String: Model] = ["Model": model]
                    NotificationCenter.default.post(name: Notification.Name("DisconnectCallFromReceiver"), object: nil, userInfo: sendModelToNotCenter)
                }
            } else {
                //here check action if it is connect then show incoming call
                if model.action == "connect" {
                    CallKitManager.shared.receiveCall(model: model, delegate: self) { (initiated) in
                        completionOfHandlingIncomingCall(initiated)
                    }
                } else {
                    let sendModelToNotCenter:[String: Model] = ["Model": model]
                    NotificationCenter.default.post(name: Notification.Name("DisconnectCallFromReceiver"), object: nil, userInfo: sendModelToNotCenter)
                }
            }
        } catch let error as NSError {
            print(error)
        }
    }
}

在＜code＞CallKitManager.shared中。receiveCall（model:model，delegate:self）｛（initiated）in completionOfHandlingIncomingCall（initiate）我向callkit报告了接收到的uuid

public func receiveCall(model: PushkitModel, delegate : CallKitDelegate, completion : @escaping (Bool) -> ()) {
    self.delegate = delegate
    self.model = model
    receiveCallDetails(delay: 0){ (initiated) in
        completion(initiated)
    }
}

public func receiveCallDetails(delay: TimeInterval, completion : @escaping (Bool) -> ()) {
    if let model = self.model, let uuid = UUID(uuidString: model.callUUID) {
        let update = CXCallUpdate()
        update.remoteHandle = CXHandle(type: .emailAddress, value: model.from)

        let bgTaskID = UIApplication.shared.beginBackgroundTask(expirationHandler: nil)
        DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + delay) {
            self.provider?.reportNewIncomingCall(with: uuid, update: update, completion: { (error) in
                if error == nil {
                }
                completion(true)
            })
            /* If you didn’t put caller information in your notification’s payload, call the reportCall(with:updated:) method of your app's provider object to update the calling interface. You can call that method at any time to update calls. For example, call it after your app fetches updated caller information from your VoIP server.*/
            // Asynchronously register with the telephony server and
            // process the call. Report updates to CallKit as needed.
            **self.provider?.reportCall(with: uuid, updated: update)**
            UIApplication.shared.endBackgroundTask(bgTaskID)

        }
    }  
}

当应用程序打开并且传入呼叫也启动时，我可以接收有效负载。但是当我在iOS 13上关闭我的应用程序时，我收到一个错误

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Killing app because it never posted an incoming call to the system after receiving a PushKit VoIP push callback.'

因为我已经报告了我的电话。如果有人有解决办法，那就太好了。

Answer 1

我认为问题是您在DispatchQueue.main.asyncAfter中报告调用。即使您将延迟设置为0，您的代码也会在下一个运行循环中运行，即不会立即运行。这样，push注册表（_： didReceiveIncomingPushWith： for：完成：）函数将在您的调用报告之前结束，因此系统会投诉。

因此，尝试删除DispatchQueue.main.asyncAfter。
