预加载图片:

1.CCTextureCache::sharedTextureCache()->addImage("icon.png");

2.CCTextureCache::sharedTextureCache()->addImageAsync("icon.png",this,callfuncO_selector(MainLayerLoading::loadingCallBack));

使用加载的缓存图片:

CCSprite* sp =CCSprite::createWithTexture(CCTextureCache::sharedTextureCache()->textureForKey("icon.png"));

释放预加载图片:

CCTextureCache::sharedTextureCache()->removeAllTextures();

预加载*.plist图片

CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("test.plist");

使用预加载的缓存*.plist图片

1.CCSprite* sp = CCSprite::createWithSpriteFrame(CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName( "icon.png" ));

2.CCSpriteFrame* frameX = CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName( "icon.png" );

释放预加载*.plist图片

CCSpriteFrameCache::sharedSpriteFrameCache()->removeSpriteFrames();
