这个是源代码 没哟addNode()函数
//加载uilayer
mainLayer = Layer::create();
// mainLayer->setPosition(VISIBLEPOINT);
Layout* _layout = static_cast<Layout*>(cocostudio::GUIReader::getInstance()->widgetFromJsonFile(“GameScene_1/GameScene_1.json”));
mainLayer->ignoreAnchorPointForPosition(false);
mainLayer->setAnchorPoint(ccp(0,0));
mainLayer->addChild(_layout);
addChild(mainLayer);
rootLayout = (Layout *)mainLayer->getChildByTag(1);
Node *node = Node::create();
rootLayout->addChild(node);
