ios - 从应用程序委托(delegate)调用时未加载调用工具包 ui

Question

我无法触发来自应用程序委托(delegate)的调用套件 UI 来电。我该怎么做呢？我尝试了扬声器盒示例，但没有帮助。当我在 ViewController 中运行 reportIncomingCall 方法时，它起作用了。当我在 AppDelegate 中运行 reportIncomingCall 时，它不起作用。我需要它在 Appdelegate 中运行，以便我可以发送 VoIP 通知来报告来电。

这是我的应用委托(delegate):

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, PKPushRegistryDelegate {

    class var shared: AppDelegate {
        return UIApplication.shared.delegate as! AppDelegate
    }

    var window: UIWindow?

    var providerDelegate: ViewController?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        return true
    }

    func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {

        //register for voip notifications
        let voipRegistry = PKPushRegistry(queue: DispatchQueue.main)
        voipRegistry.desiredPushTypes = Set([PKPushType.voIP])
        voipRegistry.delegate = self;
    }

    func pushRegistry(_ registry: PKPushRegistry, didInvalidatePushTokenForType type: PKPushType) {

         NSLog("token invalidated")

    }

    func pushRegistry(_ registry: PKPushRegistry, didUpdate credentials: PKPushCredentials, forType type: PKPushType) {

        //print out the VoIP token. We will use this to test the notification.
        NSLog("voip token: \(credentials.token)")

        print("didUpdatePushCredentials: %@ - Type: %@", credentials.token, type)
        var token: String = ""
        for i in 0..<credentials.token.count {
            token += String(format: "%02.2hhx", credentials.token[i] as CVarArg)
        }

        print(token)

    }

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

        print("notification receivd!")
        guard type == .voIP else { return }

        let uuidString = payload.dictionaryPayload["UUID"] as? String!
        let roomName = payload.dictionaryPayload["roomName"] as? String!
        print("uuid", uuidString!)
        print("roomName", roomName!)


        providerDelegate?.performStartCallAction(uuid: UUID(), roomName: "Test")

    }

    //Intents
    func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
        guard let viewController = window?.rootViewController as? ViewController, let interaction = userActivity.interaction else {
            return false
        }

        var personHandle: INPersonHandle?

        if let startVideoCallIntent = interaction.intent as? INStartVideoCallIntent {
            personHandle = startVideoCallIntent.contacts?[0].personHandle
        } else if let startAudioCallIntent = interaction.intent as? INStartAudioCallIntent {
            personHandle = startAudioCallIntent.contacts?[0].personHandle
        }

        if let personHandle = personHandle {
            viewController.performStartCallAction(uuid: UUID(), roomName: personHandle.value)
        }

        return true
    }

}

在 ViewController 类中:

extension ViewController : CXProviderDelegate {

    func providerDidReset(_ provider: CXProvider) {
        logMessage(messageText: "providerDidReset:")

        localMedia?.audioController.stopAudio()

        logMessage(messageText: "providerDidBegin")

    }

    func provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession) {
        logMessage(messageText: "provider:didActivateAudioSession:")

        localMedia?.audioController.startAudio()
    }

    func provider(_ provider: CXProvider, didDeactivate audioSession: AVAudioSession) {

        //       suggests configuring audio in the completion block of the `reportNewIncomingCallWithUUID:update:completion:`

编辑

如以下评论所述，很明显我没有设置委托(delegate)。我在 vc 中有以下初始化。当我尝试在 didFinishLaunchingWithOptons 函数中设置它时，它要求我添加参数编码器。

ViewController init
required init?(coder aDecoder: NSCoder) {
    let configuration = CXProviderConfiguration(localizedName: "TestApp")
    configuration.maximumCallGroups = 1
    configuration.maximumCallsPerCallGroup = 1
    configuration.supportsVideo = true
    if let callKitIcon = UIImage(named: "iconMask80") {
        configuration.iconTemplateImageData = UIImagePNGRepresentation(callKitIcon)
    }

    callKitProvider = CXProvider(configuration: configuration)
    callKitCallController = CXCallController()

    super.init(coder: aDecoder)

    callKitProvider.setDelegate(self, queue: nil)

}

Appdelegate/didFinishLoadingWithOptions

providerDelegate = ViewController(coder: NSCoder) //this is where its messing up.

如果对你有帮助，试试这个方法

将在 AppDelegate 中使用的我的 Call Ui 类

class CallUI : NSObject {  
    static var shared = CallUI()
    var callControllerClass = CallUIController()

    func initCall(payloadResponse Response: [AnyHashable:Any]) {
        callControllerClass.getDataSortedFromPayload(PayloadResponse: Response)
    }
}

用于处理调用 Kit Delegates 的类

class CallUIController : UIViewController, CXProviderDelegate {

    var payloadResponse : [AnyHashable:Any]?
    var notificationTypeRx : CallNotificationType?
    var providerName : String?

    let provider = CXProvider(configuration: CXProviderConfiguration(localizedName: SAppName))
    let update = CXCallUpdate()
    var uuidUsed : UUID?
    var providerConfiguration : CXProviderConfiguration?

    func getDataSortedFromPayload(PayloadResponse Response: [AnyHashable:Any]) {
        if let APSData = Response["aps"] as? [String:Any] {
            if let notifyType = APSData["type"] as? String {
                if notifyType == "calling" {
                    self.notificationTypeRx = .StartCall
                    self.showCallUI(ProviderName: nameUsed ?? "")
                }
                else if notifyType == "disconnectCalling" {
                    /// Need to Disconnect Call
                    self.notificationTypeRx = .Endcall
                    /// Dismiss if any Loaded UI
                }
                else{
                    print("Type of notification wasn't found")
                }
            }
        }
        else{
            print("Aps Data was not found")
        }
    }

    func showCallUI(ProviderName Name: String) {

        provider.setDelegate(self, queue: nil)
        uuidUsed = UUID()
        update.hasVideo = true
        update.remoteHandle = CXHandle(type: .phoneNumber, value: Name)
        provider.reportNewIncomingCall(with: uuidUsed!, update: update, completion: { error in })
    }

    func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) {
        /// Accept Action
    }

    func provider(_ provider: CXProvider, perform action: CXEndCallAction) {
        /// Decline Action
    }


    func providerDidReset(_ provider: CXProvider) {
        print("Declined Status")
    }

}

AppDelegate 用法

func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) {
   print("Payload API Response \(payload.dictionaryPayload)")
   if UIApplication.shared.applicationState == .background {
        CallUI.shared.initCall(payloadResponse: payload.dictionaryPayload)
   }
}
