OneSignal 推送通知不会触发 AppDelegate 中的事件

Question

我将OneSignal与Swift一起使用。 我成功完成了 OneSignal 设置。 当我从OneSignal Dashboard发送通知时，我的设备会显示通知。

当我点击通知时，它会按预期打开应用程序。 问题从这里开始， AppDelegate中的函数永远不会被触发。

  let notificationReceivedBlock: OSHandleNotificationReceivedBlock = { notification in

        print("Received Notification: \(notification!.payload.notificationID)")
        print("launchURL = \(notification?.payload.launchURL ?? "None")")
        print("content_available = \(notification?.payload.contentAvailable ?? false)")
    }

 let notificationOpenedBlock: OSHandleNotificationActionBlock = { result in
        // This block gets called when the user reacts to a notification received
        let payload: OSNotificationPayload? = result?.notification.payload

        if let additionalData = result!.notification.payload!.additionalData {

            print("additionalData = \(additionalData)")

            if let actionSelected = payload?.actionButtons {
                print("actionSelected = \(actionSelected)")
            }
        }
    }

我不知道我做错了什么。 请帮我解决这个问题...
