该帖子使用 cocos2d-x 3.3 的版本重新编辑了一遍

//1.保存文件函数

void HelloWorld::saveFile(SpriteFrame* pSpriteFrame, std::string name)
{
    RenderTexture* pScreen = RenderTexture::create(pSpriteFrame->getRect().size.width
                                                       ,pSpriteFrame->getRect().size.height
                                                       , Texture2D::PixelFormat::RGBA8888);

    //渲染纹理开始捕捉
    pScreen->begin();

    Sprite* pSprite = Sprite::createWithSpriteFrame(pSpriteFrame);
    pSprite->setAnchorPoint(cocos2d::Vec2::ZERO);

    //当前场景参与绘制
    pSprite->visit();

    //结束捕捉
    pScreen->end();

    //保存为png
    pScreen->saveToFile(name, Image::Format::PNG);
}

//2.解析plist
void HelloWorld::decodePlist()
{
    CCLOG("%s", FileUtils::getInstance()->getWritablePath().c_str());
    SpriteFrameCache* pSpriteFrameCache = SpriteFrameCache::getInstance();

    pSpriteFrameCache->addSpriteFramesWithFile( "SDsprite_sheet.plist" , "SDsprite_sheet.png" );

    //需要先把_spriteFrames 改成public，否则无法访问
    Map<std::string, SpriteFrame*> pDic = pSpriteFrameCache->_spriteFrames;
    CCLOG("[%s ]有 [%zd] 张图片" , "SDsprite_sheet.plist", pDic.size());

    std::vector<std::string> iKeys = pDic.keys();
    for(auto element = iKeys.begin() ; element != iKeys.end(); ++element)
    {
        std::string iK = std::string(element->c_str());
        SpriteFrame* pFrame = (SpriteFrame*)pDic.at(iK);
        saveFile(pFrame,iK);

    }

}
