【问题描述】：

我想开发一个提醒应用，当我们设置提醒时需要发送本地通知。我开发了一些代码，即使我设置了多个通知，也只会触发一个通知。如果我在晚上 7:30、晚上 7:31、晚上 7:32 设置提醒，则通知仅在晚上 7:32 显示。

这是我的代码

    func scheduleNotification(at date: Date) 
    let calendar = Calendar(identifier: .gregorian)
    let components = calendar.dateComponents(in: .current, from: date)
    let newComponents = DateComponents(calendar: calendar, timeZone: .current, month: components.month, day: components.day, hour: components.hour, minute: components.minute)
    let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: true)
    let content = UNMutableNotificationContent()
    content.title = "Reminder"
    content.body = "To day is the last date for the payment of your card. Please make payment today."
    content.sound = UNNotificationSound.default()
    content.categoryIdentifier = "PaymentReminderIdentifier"
    let request = UNNotificationRequest(identifier: "ReminderNotification", content: content, trigger: trigger)
    UNUserNotificationCenter.current().delegate = self
    //UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
    UNUserNotificationCenter.current().add(request) (error) in
        if let error = error 
            print("Uh oh! We had an error: \(error)")
        
    

//

func notif() 
    let selectedDate = fullDate
    print("Selected date: \(selectedDate)")
    let delegate = UIApplication.shared.delegate as? AppDelegate
    delegate?.scheduleNotification(at: selectedDate!)

我想在每次创建提醒时发送通知。 帮我解决这个问题。谢谢...

每次使用不同的标识符。它会工作
