代码实例：

bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }
    
    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();
	// 创建精灵类
	auto sprite = Sprite::create("taotaoahui.jpg");
	//sprite->setPosition(ccp(visibleSize.width / 2,visibleSize.height / 2));
	sprite->setAnchorPoint(ccp(0,0));
	addChild(sprite,1);


   // ParticleBatchNode 使用方法，
	 auto _emitter = ParticleSystemQuad::create("Particles/taotao.xml.particle.plist");// 首先创建ParticleSystemQuad或者ParticleSystem
	 _emitter->retain();
	 auto batch = ParticleBatchNode::createWithTexture(_emitter->getTexture());
	 batch->addChild(_emitter);
	 batch->setPosition(ccp(visibleSize.width /2,visibleSize.height /2 ));	// sjt
	 this->addChild(batch,10);
    

    return true;
