ios - 如何注册通知类别？

Question

我正在尝试注册类别，但由于某种原因我无法在 iPhone 上注册，但它可以在模拟器上运行？我使用以下代码进行注册，然后检查我订阅了哪些类别。当我在 iPhone 上运行应用程序时进行检查时，它显示 0，当我在模拟器上检查时，它显示 1。

        let snoozeAction = UNNotificationAction(identifier: "SNOOZE_ACTION",
                                            title: "Snooze",
                                            options: .foreground)
    let expiredCategory = UNNotificationCategory(identifier: "TIMER_EXPIRED",
                                                 actions: [snoozeAction],
                                                 intentIdentifiers: [],
                                                 options: UNNotificationCategoryOptions(rawValue: 0))
    let center = UNUserNotificationCenter.current()
    center.setNotificationCategories([expiredCategory])

然后我检查

    UNUserNotificationCenter.current().getNotificationCategories { categories in
            print("These are the categories\(categories.count)")
            print(categories.description)
        }

我不知道发生了什么!

Try this, I am using this and its working for me.

func notificationSetup()
{
   if #available(iOS 10.0, *)
   {
     let center = UNUserNotificationCenter.current()
      center.delegate = self
      center.requestAuthorization(options: [.alert,.badge,.sound]) { granted,error in
      if (error == nil) {
       UIApplication.shared.registerForRemoteNotifications()
      }
    } 
    let snoozeAction = UNNotificationAction(identifier: "SNOOZE_ACTION", title: "Snooze", options: [.foreground, .authenticationRequired])
    let categoryOptions = UNNotificationCategoryOptions(rawValue: 0)
    let expiredCategory = UNNotificationCategory(identifier: "TIMER_EXPIRED", actions: [snoozeAction], intentIdentifiers: [], options: categoryOptions)
    let categories = Set([expiredCategory])
    center.setNotificationCategories(categories)

   }
}
