接听电话后使用 openTok (CallKit)

Question

我正在开发一个需要 opentok 和 callkit 来通知用户的项目。但是，当 openTok 尝试连接到会话时，应用程序会不断崩溃。 IDK现在发生了什么。这是我的工作流程和代码：

推送有关可用 opentok 会话的通知 -> 开始来电 -> 用户接受呼叫 -> 启动 opentok 故事板 -> 做一些后端工作 -> 连接到会话！！！！这就是它崩溃的时候。

错误： 线程 1：EXC_BAD_ACCESS（代码=2，地址=0x1968a0ad8）

此外，我想就接收通知征求意见。而不是在屏幕上显示通知。我想使用 callkit 开始通话，例如 whatsapp 或 fb messenger。也请给我一个提示。目前，我只能在发送推送通知时应用在前台时开始通话。

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification
    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)
    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    // Print full message.
    print(userInfo)

    let aps = userInfo["aps"] as! [String: AnyObject]
    // 1
    if aps["content-available"] as? Int == 1 {

        let uuid = UUID(uuidString: MyVariables.uuid)
        AppDelegate.shared.displayIncomingCall(uuid: uuid!, handle: "Sanoste", hasVideo: false) { _ in
        }
    }else  {
        return
    }

    completionHandler(UIBackgroundFetchResult.newData)
}


func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) {

    action.fulfill()
    AppDelegate.shared.openTok()
}


func openTok() {

    let mainStoryboard = UIStoryboard(name: "callView", bundle: nil)
    let vc = mainStoryboard.instantiateViewController(withIdentifier: "callViewController") as! callViewController

    vc.view.frame = UIScreen.main.bounds
    UIView.transition(with: self.window!, duration: 0.5, options: .transitionCrossDissolve, animations: {
        self.window!.rootViewController = vc
    }, completion: nil)

}

// Join a session from MBE
func joinSession() {

    var error: OTError?

    pSession = OTSession(apiKey: openTokSessionKey.pApiKey, sessionId: openTokSessionKey.pSessionId, delegate: self as OTSessionDelegate)
    pSession?.connect(withToken: openTokSessionKey.pToken, error: &error)
    if error != nil {
        print(error!)
    }

    sSession = OTSession(apiKey: openTokSessionKey.sApiKey, sessionId: openTokSessionKey.sSessionId, delegate: self as OTSessionDelegate)
    sSession?.connect(withToken: openTokSessionKey.sToken, error: &error)
    if error != nil {
        print(error!)
    }
}

有人帮忙吗？

这次崩溃是一种警告。如果您在 Xcode 9 的项目设置中禁用“Main Thread Sanitizer”并重新构建项目，则可以解决此问题。
