	sprite->setPosition(Vec2(visibleSize.width / 2 + origin.x,visibleSize.height / 2 + origin.y));
	this->addChild(sprite,0);

	// 在Cocos2d-3.x中,增加了可以加载网页的API,但必须注意的是:到目前为止,只能在Android和iOS平台进行加载网页,如果在其他的平台,代码则会编译出错,所以需要加上平台判断的宏定义才能编译通过
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID || CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
	auto webView = cocos2d::experimental::ui::WebView::create();
	webView->setContentSize(visibleSize);
	webView->setPosition(visibleSize/2.0);
	webView->loadURL("http://www.baidu.com");
	this->addChild(webView);
