创建自定义事件：

Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

    auto listener = EventListenerCustom::create("MyEvent",[](EventCustom *event){
        CCLOG("Hello %s",(char*)event->getUserData());
    });

    Director::getInstance()->getEventDispatcher() ->addEventListenerWithFixedPriority(listener,1);

触发事件：

EventCustom e("MyEvent");
    e.setUserData((void*)("Lidaha"));

    Director::getInstance()->getEventDispatcher()->dispatchEvent(&e);
