Cocos2d 2.0 - 找不到spriteFrame？

Question

我正在使用Cocos2D 2.0开发iPad。

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"];

它因这个错误而惨遭失败：

Cocos2d：CCSpriteFrameCache：找不到框架'white.png' * 断言失败 - [CCSprite initWithSpriteFrame：]，/ Users / myUser / Files / MyApp / MyApp / libs / circos2d / CCSprite.m：212 **

我使用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2x2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

看了几个小时之后，我无法找到这些文件的任何问题......但它仍然会发生灾难性的灾难。

任何线索？感谢。

精灵帧名称应为atlas-ipadhd.plist中的white.png。

直接从马的嘴里出来：

+(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。这样，您的代码可以保持完全与设备无关，您只需使用适当的设备特定文件名提供资源（纹理和plist）。
