关于1.0转2.0的问题

// put in the name of the animation and the plist file - .plist
CCAnimation * GameObject::loadPlistForAnimationWithName(const char *animationName, const char *pszPlist)
{
	CCAnimation *animationToReturn = NULL;

	const char *plistPath = CCFileUtils::fullPathFromRelativePath(pszPlist);

	CCDictionary<std::string, CCObject*> *plistDictionary = CCFileUtils::dictionaryWithContentsOfFile(plistPath);

	if (plistDictionary == NULL)
	{
		CCLOG("Error reading plist: %s", pszPlist);
		return NULL;
	}

	//using a string to string dictionary to convert a CCString to float
	CCDictionary<std::string, CCString*> *animationSettings = (CCDictionary<std::string, CCString*> *) plistDictionary->objectForKey(std::string(animationName));
	if (animationSettings == NULL)
	{
		CCLOG("Could not locate AnimationWithName: %s", animationName);
		return NULL;
	}

	float animationDelay =  animationSettings->objectForKey(std::string("delay"))->toFloat();

	animationToReturn = CCAnimation::animation();
	animationToReturn->setDelay(animationDelay);
	
	string animationFramePrefix = animationSettings->objectForKey(std::string("filenamePrefix"))->toStdString();
	string animationFrames = animationSettings->objectForKey(std::string("animationFrames"))->toStdString();
	
	vector<string> animationFrameNumbers = split(animationFrames, ',');
	vector<string>::iterator it;
	string frameNumber = "0";

	for (it = animationFrameNumbers.begin(); it < animationFrameNumbers.end(); it++)
	{
		frameNumber = *it;
		char frameName = {0};
		sprintf(frameName, "%s%s.png", animationFramePrefix.c_str(), frameNumber.c_str());
		animationToReturn->addFrame(CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(frameName));
	}

	return animationToReturn;
}

这段代码是从plist中加载动画，是用1.0写的，用2.0编译不通过，请问该怎么转为2.0？
谢谢
