cocos2dx3.4 分割plist图片

如果想要修改一个plist文件新打包成plist，而此刻原来的小图都找不到了，那只能把plist分解了，代码如下：

void UiManage::DecodePlist(string imgPath,string plistPath)

{

    FileUtils *pFileUtil=FileUtils::getInstance();

    SpriteFrameCache *pFramChace=SpriteFrameCache::getInstance();

    pFramChace->addSpriteFramesWithFile(plistPath,imgPath);



    ValueMap plistDic=pFileUtil->getValueMapFromFile(plistPath);

    if (plistDic.find("frames")!=plistDic.end())

    {

        Point pos(0,0);



        ValueMap framesDic=plistDic["frames"].asValueMap();

        for (auto it=framesDic.begin();it!=framesDic.end();it++)

        {

            string imgName=it->first;

            string savePath="screenshot/"+imgName;

            //SpriteFrame *pFrame=pFramChace->getSpriteFrameByName(imgName);

            Sprite *pSpr=Sprite::createWithSpriteFrameName(imgName);

            if (pSpr)

            {

                Size imgSize=pSpr->getContentSize();

                RenderTexture *pRenderTexture=RenderTexture::create(imgSize.width,imgSize.height);





                pRenderTexture->begin();



                pRenderTexture->setAnchorPoint(pos);

                pSpr->setAnchorPoint(pos);

                pSpr->setPosition(pos);

                pSpr->visit();



                pRenderTexture->end();

                pRenderTexture->saveToFile(savePath,Image::Format::PNG);

                CCLOG("save img %s",imgName.c_str());



                //CC_SAFE_RELEASE(pRenderTexture);

                //CC_SAFE_RELEASE(pSpr);

                pFramChace->removeSpriteFrameByName(imgName);

            }



        }

    }

}
