2.VC里面

import UIKit

class ViewController: UIViewController {

    @IBAction func sendNotification(_ sender: Any) {
        
        /// 创建
        let localNotification = UILocalNotification()

            localNotification.alertTitle = "斗地主卡卡"
        }
        
        //此处的 category 和 AppDelegate里面设置的要一样
        localNotification.category = "selected"
        
        //设置内容
        localNotification.alertBody = "通知来了"
        
        //几秒之后执行
        localNotification.fireDate = Date(timeIntervalSinceNow: 2)
