如何在swift中及时触发本地通知？

import UIKit
import UserNotifications

class ViewController: UIViewController, UNUserNotificationCenterDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 请求用户授权通知权限
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
            if granted {
                print("用户授权通知权限成功")
            } else {
                print("用户授权通知权限失败")
            }
        }
        
        // 设置通知中心的代理
        UNUserNotificationCenter.current().delegate = self
    }
    
    // 创建并触发本地通知
    func triggerLocalNotification() {
        let content = UNMutableNotificationContent()
        content.title = "本地通知标题"
        content.body = "本地通知内容"
        content.sound = UNNotificationSound.default
        
        // 设置通知触发条件为立即触发
        let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 0, repeats: false)
        
        // 创建通知请求
        let request = UNNotificationRequest(identifier: "LocalNotification", content: content, trigger: trigger)
        
        // 将通知请求添加到通知中心
        UNUserNotificationCenter.current().add(request) { (error) in
            if let error = error {
                print("添加本地通知失败：\(error.localizedDescription)")
            } else {
                print("添加本地通知成功")
            }
        }
    }
    
    // 实现通知中心的代理方法，处理通知的点击事件
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        if response.actionIdentifier == UNNotificationDefaultActionIdentifier {
            print("用户点击了通知")
        }
        
        completionHandler()
    }
}
