Question

我试图为支持iOS 9,10和11的远程通知添加UNNotificationAction按钮几天。我按照多个教程中的所有步骤进行操作，其中大多数都使用本地通知来显示UNNotificationAction到目前为止工作。但是它对我的远程通知不起作用。我可以通过Firebase发送远程通知。如果我的代码的某些部分不正确或缺少部件来配置UNNotificationAction按钮，请告诉我。

我的AppDelegate中的那些代码，

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    FirebaseApp.configure()
    requestNotificationAuthorization(application: application)
    }
    return true
}

func requestNotificationAuthorization(application: UIApplication) {
    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().delegate = self
        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(options: authOptions, completionHandler: {granted, error in

            if (granted)
            {
                let viewAction = UNNotificationAction(identifier: "viewAction", title: "View", options: [])

                let closeAction = UNNotificationAction(identifier: "closeAction", title: "Close", options: [])
                // 2
                let buttonCategory = UNNotificationCategory(identifier: "buttonCategory", actions: [viewAction, closeAction], intentIdentifiers: [], options: [])
                // 3
                UNUserNotificationCenter.current().setNotificationCategories([buttonCategory])
                DispatchQueue.main.async {
                   application.registerForRemoteNotifications()
                }
                print("Granted")
            }
        })
    } else {
        let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: notificationAction() as? Set<UIUserNotificationCategory>)
        application.registerUserNotificationSettings(settings)
        DispatchQueue.main.async {
            application.registerForRemoteNotifications()
        }
    }
}

func notificationAction() -> NSSet {
    let firstAction: UIMutableUserNotificationAction = UIMutableUserNotificationAction()
    firstAction.identifier = "First_Action"
    firstAction.title = "View"
    firstAction.activationMode = .foreground
    firstAction.isDestructive = false
    firstAction.isAuthenticationRequired = false

    let secondAction: UIMutableUserNotificationAction = UIMutableUserNotificationAction()
    secondAction.identifier = "Second_Action"
    secondAction.title = "Close"
    secondAction.activationMode = .background
    secondAction.isDestructive = false
    secondAction.isAuthenticationRequired = false

    //category
    let firstCategory : UIMutableUserNotificationCategory = UIMutableUserNotificationCategory()
    firstCategory.identifier = "buttonCategory"

    let defaultAction = [firstAction,secondAction]
    let mininalAction = [firstAction,secondAction]

    firstCategory.setActions(defaultAction, for: UIUserNotificationActionContext.default)
    firstCategory.setActions(mininalAction, for: UIUserNotificationActionContext.minimal)

    //NSSet of category
    let categories = NSSet(object: firstCategory)

    return categories
}

@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
// iOS10+, called when presenting notification in foreground
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

    completionHandler([.alert])
}

// iOS10+, called when received response (default open, dismiss or custom action) for a notification
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    if(response.actionIdentifier == "viewAction"){
        print("viewing Action")
    }

    if(response.actionIdentifier == "closeAction"){
        print("closing Action")
    }

    completionHandler()
  }
}

要通过Firebase进行iOS远程通知，需要执行多个步骤，其中许多步骤与代码无关。首先，请确保您能够发送/接收简单的纯文本通知，而无需执行操作。

一旦生效，然后查看您是否收到内置动作UNNotificationDefaultActionIdentifier和UNNotificationDismissActionIdentifier。

如果可行，那么您只需要委托方法和requestNotificationAuthorization方法中的代码-您的notificationAction()方法似乎是不必要的。
