problem with loading pvr

help guys.
and my code is:

CCTexture2D::PVRImagesHavePremultipliedAlpha(true);
    CCSpriteFrameCache *cache = CCSpriteFrameCache::sharedSpriteFrameCache();
    cache->addSpriteFramesWithFile(CCString::stringWithFormat("%s", "aaa.plist")->getCString(), CCString::stringWithFormat("%s", "aaa.pvr.ccz")->getCString());
    CCArray *spriteFrames = CCArray::arrayWithCapacity(8);
    for(int i = 1; i<9; i++){
        CCString *frameName = CCString::stringWithFormat("%d%s", i, ".png");
        CCSpriteFrame *frame = cache->spriteFrameByName(frameName->getCString());
        spriteFrames->addObject(frame);
    }
    CCAnimation *animation = CCAnimation::animationWithSpriteFrames(spriteFrames, 0.4);
    CCRepeatForever::actionWithAction(CCAnimate::actionWithAnimation(animation));
    cache->removeSpriteFramesFromFile(CCString::stringWithFormat("%s", "aaa.plist")->getCString());

and always error:

I’m a new guy.
plz help!
thanks advanced!

you could check your file path of aaa.pvr.ccz.

it’s in Resource, and not just reference.
I run it in Simulator on my iMac, is it the problem?
