如何在iOS中安排可以暂停或删除的本地通知？

import UserNotifications

// 创建通知内容
let content = UNMutableNotificationContent()
content.title = "提醒"
content.body = "这是一个本地通知示例"
content.sound = UNNotificationSound.default

// 创建通知触发条件
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, 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")
    }
}

// 暂停通知
UNUserNotificationCenter.current().getPendingNotificationRequests { (requests) in
    for request in requests {
        if request.identifier == "localNotification" {
            UNUserNotificationCenter.current().removePendingNotificationRequests(withIdentifiers: [request.identifier])
            print("暂停本地通知成功")
        }
    }
}

// 删除通知
UNUserNotificationCenter.current().removeDeliveredNotifications(withIdentifiers: ["localNotification"])
print("删除本地通知成功")

import UIKit
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // 请求用户授权
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
            if granted {
                print("用户已授权通知")
            } else {
                print("用户未授权通知")
            }
        }
        
        UNUserNotificationCenter.current().delegate = self
        
        return true
    }
    
    // 在应用前台显示通知
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        completionHandler([.alert, .sound, .badge])
    }
}
