【问题描述】：

我想创建一个在应用运行时将显示在通知中心的 userNotification。 单击通知将终止应用程序。

需要使用哪个触发器？ 如何实现此功能？

【参考方案1】：

试试这个。

func scheduleNotification(at date: Date, body: String) 
    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: false)

    let content = UNMutableNotificationContent()
    content.title = "Dont Forget"
    content.body = body
    content.sound = UNNotificationSound.default()

    let request = UNNotificationRequest(identifier: "textNotification", 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)")
