cocos2d:Failed loading resource: res/coins.pvr.ccz

cocos2d-x JavaScript
#1

ch5 2.2.2

我按照这个来做的http://farsa.blog.51cto.com/6172595/1155964
ctor里面

cc.Texture2D.PVRImagesHavePremultipliedAlpha(true);  //pvr.czz
cc.SpriteFrameCache.getInstance().addSpriteFrames(res.s_coinsPlist);
var coin = cc.Sprite.createWithSpriteFrameName("coin01.png");

coin.setPosition(cc.p(200,200));
this.addChild(coin);

控制台cocos2d:Failed loading resource: res/coins.pvr.ccz ，程序可以运行，但是没有这个Sprite。
在TP里面，我设置为正方形512*512,勾选了premultiply alpha
请问，这个问题怎么解决，在ch5里面怎么使用pvr.czz？

Hi, @tellyounews

Sorry we didn’t support pvr format, because the pvr file is only supported by iOS devices’ graphic card. So it won’t bring you any performance improvement in browsers.

Oh, you mean in JSB, can you check whether this file exist or not and whether it have been added to your resource bundle in your Xcode Project?
