【问题描述】：

我想在我的应用收到通知时显示通知自定义操作按钮。但是什么也没发生！任何人都可以帮助我吗？谢谢。

这是我的AppDelegate.swift 代码：

class AppDelegate: UIResponder, UIApplicationDelegate 

    var window: UIWindow?

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

        // Register ourselves as a delegate so we can be notified when actions pressed.
        UNUserNotificationCenter.current().delegate = self

        // Request permission.
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert]) 
            granted, error in
            if granted 
                print("Approval granted to send notifications")
            
        

        self.addCategory()

        return true
    

    func addCategory() 
        // Add action.
        let stopAction = UNNotificationAction(identifier: "stop", title: "Stop", options: [])
        let snoozeAction = UNNotificationAction(identifier: "snooze", title: "Snooze", options: [])

        // Create category.
        let category = UNNotificationCategory(identifier: "reminder", actions: [stopAction, snoozeAction], intentIdentifiers: [], options: [])

        UNUserNotificationCenter.current().setNotificationCategories([category])
    

UNUserNotificationCenterDelegate

extension AppDelegate: UNUserNotificationCenterDelegate 

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

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 
        print("Called when a notification is delivered to a foreground app.")
        NotificationCenter.default.post(name: NSNotification.Name(rawValue: "notificationPresentAtForeground"), object: nil)
        completionHandler([.alert])
    

【参考方案1】：

我找到了答案。我没有设置我的通知内容类别标识符。 以下对我有用：

content.categoryIdentifier = "reminder"
