我正在尝试在我的应用程序中实现本地通知。 这个想法是每天上午9:00给用户发送一个通知，其中有一个不同的引用，但我遇到了一个bug，通知的相同内容总是显示，即同一个引用无休止地重复。 我该怎么修好呢？ 这就是我正在使用的代码，并且我尝试为发送的每个通知使用UUID，但是它并没有带来改进。

    let notificationCenter = UNUserNotificationCenter.current()
    let options: UNAuthorizationOptions = [.alert, .sound]
    notificationCenter.requestAuthorization(options: options) {
        (didAllow, error) in
        if !didAllow {
            print("User has declined notifications")
        }
    }

    notificationCenter.getNotificationSettings { (settings) in
      if settings.authorizationStatus != .authorized {
        print("Notifications not allowed")
      }
    }
    
    let randomArrayNotificationQuote = Int(arc4random_uniform(UInt32(myQuotes.count)))
    let randomArrayNotificationTitle = Int(arc4random_uniform(UInt32(myTitle.count)))
    
    let content = UNMutableNotificationContent()
    content.title = "\(myTitle[randomArrayNotificationTitle])"
    content.body = "\(myQuotes[randomArrayNotificationQuote])"
    content.sound = UNNotificationSound.default
    content.categoryIdentifier = "com.giovannifilippini.philo"
    
    // Deliver the notification
    
    var dateComponents = DateComponents()
    dateComponents.hour = 9
    dateComponents.minute = 00
    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
    
    let uuid = UUID().uuidString
    
    let request = UNNotificationRequest.init(identifier: uuid, content: content, trigger: trigger)
    
    notificationCenter.add(request) { (error) in
        if error != nil {
            print("add NotificationRequest succeeded!")
            notificationCenter.removePendingNotificationRequests(withIdentifiers: [uuid])
        }
    }
