原文： CCSpriteFrameCache的用法

先用zwoptexapp.com制作文件AnimBear.plist和AnimBear.png

cocos2d-x代码:

		CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("AnimBear.plist");
		CCSpriteBatchNode* spriteSheet = CCSpriteBatchNode::batchNodeWithFile("AnimBear.png");

		this->addChild(spriteSheet);

		CCArray *walkAnimFrames = new CCArray();
		for(int i = 1; i <= 8; ++i) {		
			walkAnimFrames->addObject(
				CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(
					CCString::stringWithFormat("bear%d.png", i)->getCString()
				)
			);
		}

		CCAnimation *walkAnim = CCAnimation::animationWithSpriteFrames(walkAnimFrames, 0.1f);

		CCSize winSize = CCDirector::sharedDirector()->getWinSize();
		CCSprite* bear = CCSprite::spriteWithSpriteFrameName("bear1.png"); 
		bear->setPosition(ccp(winSize.width/2, winSize.height/2));
		
		CCRepeatForever* walkAction = CCRepeatForever::actionWithAction(
			CCAnimate::actionWithAnimation(walkAnim)
		);

		bear->runAction(walkAction);

		this->addChild(bear);
