    //3.设置弹出提示的内容

    notification.alertBody = @"吃饭啦啦啦啦";

    

    //4.设置按钮的标题

    notification.alertAction = @"提醒";

    

    

    //注册本地通知，注册之后，通知才会生效

    [[UIApplication sharedApplication] scheduleLocalNotification:notification];

    

    //设置消息提醒的数目

}

//UIAppDelegate中设置

@implementation AppDelegate
