js里面，事件正常注册，logcat也能看到按键事件
但是，就是不执行js里面的回调部分
追根溯源，找到了上面的jni代码，发现引擎就是跑到这里然后直接返回true，不会去调用js
logcat

并且在代码头部找到了
// std::unordered_map<int, cocos2d::EventKeyboard::KeyCode> g_keyCodeMap =
// {
// { KEYCODE_BACK , cocos2d::EventKeyboard::KeyCode::KEY_ESCAPE },
// { KEYCODE_MENU , cocos2d::EventKeyboard::KeyCode::KEY_MENU },
// { KEYCODE_DPAD_UP , cocos2d::EventKeyboard::KeyCode::KEY_DPAD_UP },
// { KEYCODE_DPAD_DOWN , cocos2d::EventKeyboard::KeyCode::KEY_DPAD_DOWN },
// { KEYCODE_DPAD_LEFT , cocos2d::EventKeyboard::KeyCode::KEY_DPAD_LEFT },
// { KEYCODE_DPAD_RIGHT , cocos2d::EventKeyboard::KeyCode::KEY_DPAD_RIGHT },

// { KEYCODE_PLAY , cocos2d::EventKeyboard::KeyCode::KEY_PLAY },
// { KEYCODE_DPAD_CENTER , cocos2d::EventKeyboard::KeyCode::KEY_DPAD_CENTER },
// };
所以这个要弃用了？
