import UserNotifications

let content = UNMutableNotificationContent()
content.title = "通知标题"
content.body = "通知正文"
content.sound = UNNotificationSound.default
// 设置其他属性...

let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: false)
// 设置其他触发器属性...

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

let center = UNUserNotificationCenter.current()
center.add(request) { (error) in
    if let error = error {
        print("添加通知失败：\(error.localizedDescription)")
    }
}

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
    // ...
    
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        // 处理通知点击事件
        completionHandler()
    }
}
