Cocos2d iphone Cocos2d 2.0-找不到spriteFrame？

我正在用CoCoS2D2.0为iPad开发

我有以下几行：

[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"atlas.plist"];
CCSpriteBatchNode *batchNode = [CCSpriteBatchNode batchNodeWithFile:@"atlas.png"];
[self addChild:batchNode];

CCSprite *mySprite = [CCSprite spriteWithFrameName:@"white.png"];

它因以下错误而惨败：

Cocos2d:CCSpriteFrameCache:Frame'white.png'未找到 *在-[CCSprite initwithpriteframe:]、/Users/myUser/Documents/MyApp/MyApp/libs/cocos2d/CCSprite.m:212中断言失败**

我已经使用TexturePacker生成了plist。TexturePacker创建了4个文件：atlas-ipadhd.plis、atlas-ipadhd.png、atlas.plist和atlas.png

white-ipadhd.png是一张2x2的白色图片。white.png是1x1白色图片。

这是atlas ipadhd的内容

这是atlas-ipadhd.png和atlas.png

在看了几个小时后，我找不到这些文件有什么问题。。。但它仍然以灾难性的方式崩溃

有什么线索吗？谢谢。

atlas-ipadhd.plist中的精灵框架名称应为white.png

直接从马的嘴里：

+(id)spriteWithSpriteFrameName:(NSString*)spriteFrameName
{
    CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:spriteFrameName];

    NSAssert1(frame!=nil, @"Invalid spriteFrameName: %@", spriteFrameName);
    return [self spriteWithSpriteFrame:frame];
}

没有尝试使用设备特定键更正帧名称。通过这种方式，您的代码可以保持完全的设备无关性，您只需为资源（纹理和plists）提供适当的设备特定文件名。

为什么？每个plist不应该参考他们的对应文件吗？为什么ipadhd plist应该引用非hd文件？我想这是coco程序员的设计决定。coco为什么选择如此丑陋的xml模式？
