Solution:

in CCParticleExample.h

class CC_DLL CCParticleRain : public CCParticleSystemQuad
{
public:
    CCParticleRain(){}
    virtual ~CCParticleRain(){}
    bool init(){ return initWithTotalParticles(1000); }
    virtual bool initWithTotalParticles(unsigned int numberOfParticles);
    static CCParticleRain * node()
    {
        return create();
    }
    static CCParticleRain * create()
    {
        CCParticleRain *pRet = new CCParticleRain();
        if (pRet->init())
        {
            pRet->autorelease();
            return pRet;
        }
        CC_SAFE_DELETE(pRet);
        return NULL;
    }
};

to

in in CCParticleExample.cpp

CCParticleRain* CCParticleRain::node()
{
    return CCParticleRain::create();
}

CCParticleRain* CCParticleRain::create()
{
    CCParticleRain* pRet = new CCParticleRain();
    if (pRet && pRet->init())
    {
        pRet->autorelease();
    }
    else
    {
        CC_SAFE_DELETE(pRet);
    }
    return pRet;
}
