class TSSprite : public CCSprite ,public CCTouchDelegate

    static TSSprite*  create(const char *pszFileName);

    virtual void onEnter();
    virtual void onExit();
    virtual bool ccTouchBegan(CCTouch* touch, CCEvent* event);

};


#endif /* defined(__TSSpiriteTouch__TSSpirte__) */

关键点在于需要继承CCTouchDelegate. 然后完成相应的虚函数.
