如何在CVcalendar中根据具体时间进行每日本地通知？

import UserNotifications

let calendar = Calendar.current
let date = Date()

let components = calendar.dateComponents([.year, .month, .day], from: date)
var notificationDateComponents = DateComponents()
notificationDateComponents.year = components.year
notificationDateComponents.month = components.month
notificationDateComponents.day = components.day
notificationDateComponents.hour = 8
notificationDateComponents.minute = 0

let content = UNMutableNotificationContent()
content.title = "每日提醒"
content.body = "这是每天早上的提醒"
content.sound = UNNotificationSound.default

let trigger = UNCalendarNotificationTrigger(dateMatching: notificationDateComponents, repeats: true)

let request = UNNotificationRequest(identifier: "DailyNotification", content: content, trigger: trigger)

let center = UNUserNotificationCenter.current()
center.add(request) { (error) in
    if let error = error {
        print("添加通知请求失败：\(error.localizedDescription)")
    } else {
        print("成功添加每日本地通知")
    }
}
