要在Cocos2d中使用Button，首先引入头文件#include "ui/CocosGUI.h" using namespace uil;

引入完毕后，就创建button。代码如下：

void btnGoodsItem(cocos2d::Ref* pSender,Widget::TouchEventType event);

void HelloWorld::btnGoodsItem(cocos2d::Ref* pSender,Widget::TouchEventType event)
{
	if (event == Widget::TouchEventType::ENDED)
	{
		CCLOG("touch ended");
		auto scene03=firstscene::createScene();
	Director::getInstance()->replaceScene(scene03);
	}
}

               auto btnBuy = Button::create("CloseNormal.png","CloseSelected.png","CloseNormal.png");
	btnBuy->addTouchEventListener(CC_CALLBACK_2(HelloWorld::btnGoodsItem,this));
        btnBuy->setPosition(cocos2d::Vec2(97.39,29.34));
	this->addChild(btnBuy);
        btnBuy->setPressedActionEnabled(true);
