1. class HelloWorld : public cocos2d::CCLayer

4. do
5. {

--实际用法demo

#define EventManager NotificationCenter::getInstance()

void PlayScene::init_listen(){
EventManager->addObserver(this, CC_CALLFUNCO_SELECTOR(PlayScene::handler_refresh_hand_card), GameEvent::handler_refresh_hand_card, NULL);
EventManager->addObserver(this, CC_CALLFUNCO_SELECTOR(PlayScene::handler_refresh_all_card), GameEvent::handler_refresh_all_card, NULL);
}

EventManager->postNotification(GameEvent::on_msg, sm);

EventManager->removeAllObservers(this);
