我正在尝试关注this document以便在我的应用中设置一些通知。但这只是部分起作用。

更准确地说，我收到了预期的通知，但没有选择答案（在文档示例中为“接受-拒绝”）。下面是我的代码（相关部分），我使用“ action-One”和“ action-Two”而不是“ accept”和“ Decline”；但是除此之外，我尝试遵循该文档。

构建通知：

let notification = UnmutableNotificationContent()
notification.title = notificationInfo.title
notification.body = notificationInfo.body
notification.sound = UNNotificationsound.default

if let data = notificationInfo.data {notification.userInfo = data}

// Define the custom actions.
let actionOne = UNNotificationaction(identifier: "actION_ONE",title: "action-One",options: UNNotificationactionOptions(rawValue: 0))
let actionTwo = UNNotificationaction(identifier: "actION_TWO",title: "action-Two",options: UNNotificationactionOptions(rawValue: 0))
// Define the notification type
let userReactionCategory =
      UNNotificationCategory(identifier: "USER_REact",actions: [actionOne,actionTwo],intentIdentifiers: [],hiddenPreviewsBodyPlaceholder: "",options: .customDismissaction)
// Register the notification type.
let notificationCenter = UNUserNotificationCenter.current()
notificationCenter.setNotificationCategories([userReactionCategory])

notification.categoryIdentifier = "USER_REact"

return notification

userNotificationCenter：didReceive：withCompletionHandler 函数：

func userNotificationCenter(_ center: UNUserNotificationCenter,didReceive response: UNNotificationResponse,withCompletionHandler completionHandler: @escaping () -> Void) {
           
    let traceRecord = TraceUnit(context: self.moc) // To leave some logs in a DB.
    
      // Perform the task associated with the action.
      switch response.actionIdentifier {
      case "actION_ONE":
         traceRecord.name = "actION_ONE"
         break
      case "actION_TWO":
         traceRecord.name = "actION_TWO"
         break
      // Handle other actions…
      default:
         traceRecord.name = "actION_DEFAULT"
         break
      }
       
      traceRecord.timeStamp = Date()
    
    do {
        try self.moc.save()
    } catch let error {
        // Handle the Core Data error.
        print("Can't save as expected!!!!")
        print("Error : \(error)")
      }
    
      // Always call the completion handler when done.
      completionHandler()
}

尝试不同的选项后。我见过调用 userNotificationCenter：didReceive：withCompletionHandler 函数，但是里面的switch块似乎没有执行，甚至是默认部分。

任何人都可以指出我在参考文档中没有正确遵循的内容，以使其无法正常工作吗？
