更新到swift 4后，UNUserNotification不起作用

Question

所以我有一个交互式推送通知，但它突然停止工作，这是我的代码：

func pushNotification(){
    let content = UNMutableNotificationContent()
    let answer1 = UNNotificationAction(identifier: "answer1", title: "thank you!", options: UNNotificationActionOptions.foreground)

    let category = UNNotificationCategory(identifier: "myCategory", actions: [answer1, answer2], intentIdentifiers: [], options: [])
    UNUserNotificationCenter.current().setNotificationCategories([category])
    content.sound = UNNotificationSound.default()
    //Created notification
    content.body = "how are you?"
    content.categoryIdentifier = "myCategory"
    content.badge = 1
    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 10, repeats: false)
    let request = UNNotificationRequest(identifier: "timerDone", content: content, trigger: trigger)
    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}



@objc(userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler:) func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)
    {

        if response.actionIdentifier == "answer1"
        {
            print("ok")
            performSegue(withIdentifier: "FastResult", sender: self)
        }

        completionHandler()
    }

当我运行应用程序时，我收到了通知，但没有收到输出："ok“，并且没有segue。

只有当你点击“response.actionIdentifier ==”时，"answer1“才是真的。通知中的选项。如果你只是点击通知，那就不是真的。请查收
