    CCSpriteFrame* frame = CCSpriteFrame::createWithTexture(

        texture, CCRectMake(0,0,texture->getContentSize().width / 4,texture->getContentSize().height));

    CCARRAY_FOREACH(objs, obj)

    {

        //通过下面的方式获得object中的参数信息

        CCDictionary* dict = (CCDictionary*)obj;

        const CCString* name = dict->valueForKey("name");

        const CCString* x = dict->valueForKey("x");

        const CCString* y = dict->valueForKey("y");

        if (type->m_sString == "mushroom")

        {

            //创建一个蘑菇怪Mushroom0.png

            CCSprite* sprite = CCSprite::createWithSpriteFrame(frame);

            map->addChild(sprite);

            sprite->setPosition(ccp(x->intValue(),y->intValue()));

            sprite->setZOrder(10000);

        }

        //如果object对象的名字是Birthday，那么将执行以下的操作

        if (type->m_sString == "BirthPoint")

        {

            CCSprite* sprite = CCSprite::createWithSpriteFrame(frame);

            map->addChild(sprite);

            sprite->setPosition(ccp(x->intValue(),y->intValue() - 16));

            //如果不设置这一句，马里奥会在山后

            sprite->setZOrder(10000);

            //设置锚点

            sprite->setAnchorPoint(ccp(0,0));

        }

    }

    return true;

}

运行结果：
