依据名字查找控件

须要包括的头文件及名字空间：

#include "cocostudio/CocoStudio.h"
#include "ui/CocosGUI.h"
using namespace cocos2d::ui;
using namespace cocostudio;
注：project中须要附加包括的头文件文件夹：$(EngineRoot)cocos\editor-support。由于cocostudio在此文件夹下。

获取UI控件的方法例如以下:

   m_achievementLayer = dynamic_cast<Layout*>(GUIReader::getInstance()->widgetFromJsonFile("achievements/achievements.json"));
   addChild(m_achievementLayer);

   Widget* scoreWidget = dynamic_cast<Widget*>(m_achievementLayer->getChildByName("ImageView_231"));
   m_score = dynamic_cast<TextAtlas*>(scoreWidget->getChildByName("LabelAtlas_307"));
   m_score->setStringValue("45");

加入button回调事件

   Button* startButton = dynamic_cast<Button*>(m_achievementLayer->getChildByName("Button_336"));
   startButton->addTouchEventListener(this, toucheventselector(GameScene::touchStartButton)); 

回调函数实现：

void GameScene::touchStartButton(Ref* pSender, TouchEventType type)
{
       switch (type)
       {
        case TOUCH_EVENT_ENDED:
        //do something
        break;
       }
}
