 1 //如何监听按键事件
 2     //创建物理按键的监听事件
 3     auto listener = EventListenerKeyboard::create();
 4     //按键被释放时执行的操作,EventKeyboard::KeyCode表示按键代码
 5     listener->onKeyReleased = [](EventKeyboard::KeyCode code,Event *e){
 6         log("Key Code : %d",code);//显示按键的值
 7         //按下后退键关闭程序
 8         switch (code) {
 9             //获得物理按键
10             case EventKeyboard::KeyCode::KEY_BACKSPACE:
11                 //关闭程序
12                 Director::getInstance()->end();
13                 break;
14                 
15             default:
16                 break;
17         }
18         
19         
20     };
21     //进行监听
22     Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, this);
