swift - 本地通知

1.

AppDelegate  注册

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        regisigerNotification()
        return true
    }

    //注册本地通知
    private func regisigerNotification(){
//        let type : [UIUserNotificationType] = [.alert, .badge, .sound]
        if #available(iOS 8.0, *) {
            let uns = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            UIApplication.shared.registerUserNotificationSettings(uns)
        }
    }

}

　　

2. VC 使用

class ViewController: UIViewController {

    @IBAction func sendNotification(_ sender: Any) {

        /// 创建
        let localNotification = UILocalNotification()
        //设置标题
        localNotification.alertBody = "通知来了"

        //几秒之后执行
        localNotification.fireDate = Date(timeIntervalSinceNow: 2)

        //立即发送
//        UIApplication.shared.presentLocalNotificationNow(localNotification)

        //发送:按照设置的执行时间发送
        UIApplication.shared.scheduleLocalNotification(localNotification)
    }

    //取消
    @IBAction func cancleNotification(_ sender: Any) {
        UIApplication.shared.cancelAllLocalNotifications()
    }

    //查看
    @IBAction func viewNotification(_ sender: Any) {
    print(UIApplication.shared.scheduledLocalNotifications)
    }

}
