cocos2d-x 3.1 android 平台 响应返回键 疑问？403.10 禁止访问：配置无效

下边的代码是正确的：
auto listener = EventListenerKeyboard::create(); listener->onKeyReleased = CC_CALLBACK_2(WelcomeScene::onKeyReleased, this);

_eventDispatcher->addEventListenerWithSceneGraphPriority(listener, this);

但是下边的确是无效的：
EventListenerKeyboard* listener = EventListenerKeyboard::create(); listener->onKeyReleased = CC_CALLBACK_2(WelcomeScene::onKeyReleased, this);

_eventDispatcher->addEventListenerWithSceneGraphPriority(listener, this);

请问下  这是为什么啊？

addEventListenerWithSceneGraphPriority(),不知道是不是我见过有史以来最长的C++方法名,2dx感觉更像是Java编码风格套上C++语言(再带上Object C的一点气质)的怪胎.当然仅仅是个人喜好.不喜勿喷.

######可是3.0版本开始就有这个了，网上好多源码包括官方test工程都是用这个。。######// 初始化并绑定

//auto kblsnr = EventListenerKeyboard::create();

EventListenerKeyboard* kblsnr = EventListenerKeyboard::create();

kblsnr->onKeyReleased = CC_CALLBACK_2(LayerGame::onKeyReleased, this);

Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(kblsnr, this);
