Question

我正在尝试在iPhone上测试一个Cocos2D应用程序，并从控制台复制这个崩溃：

    cocos2d: CCSpriteFrameCache: Trying to use file 'heroTestSheet.png' as texture
    cocos2d: CCTexture2D. Can't create Texture. UIImage is nil
    cocos2d: Couldn't add image:heroTestSheet.png in CCTextureCache

在模拟器中运行它运行正常，但是当它启动时我仍然在控制台中收到此消息“ CCSpriteFrameCache：尝试使用文件'heroTestSheet.png'作为纹理”

我怀疑是问题出现的地方。也许我只是理解我的英雄精灵子类的代码应该如何编写。我认为heroTestSheet.png是依赖于分割成引用plist的其他图像的纹理。

这是我的英雄子类中的初始化：

    -(id) init{
    self = [super init];
    if (!self) {
        return nil;
    }

    _collisWidthFromCtr  = 16;
    _collisHeightFromCtr = 16;

    _collisPushPointsNums = 5;

    _travelRectCenterPoints = [[NSMutableArray alloc] init];

    _collisPushPoints = [[NSMutableArray alloc] init];

    [_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake( _collisWidthFromCtr, _collisHeightFromCtr)] atIndex:0];
    [_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake( _collisWidthFromCtr,                    0)] atIndex:1];
    [_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake( _collisWidthFromCtr,-_collisHeightFromCtr)] atIndex:2];
    [_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake( 0,                   _collisHeightFromCtr)] atIndex:3];
    [_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake(-_collisWidthFromCtr, _collisHeightFromCtr)] atIndex:4];

    _rectCheckRes = 32;

    _speed = 8;

    [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"heroTestSheet.plist"];

    _heroSpriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"heroTestSheet.png"];

    //[self addChild:_heroSpriteSheet];

    NSMutableArray *heroSpriteFlyAnimFrames = [NSMutableArray array];
    for(int i = 1; i <= 2; ++i) {
        [heroSpriteFlyAnimFrames addObject:
         [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
          [NSString stringWithFormat:@"heroFrame%d.png", i]]];
    }

    CCAnimation *heroSpriteFlyAnim = [CCAnimation animationWithFrames:heroSpriteFlyAnimFrames delay:0.03f];

    _heroSprite = [CCSprite spriteWithSpriteFrameName:@"heroFrame1.png"];  

    _heroSpriteFlyAction = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:heroSpriteFlyAnim restoreOriginalFrame:NO]];
    [_heroSprite runAction:_heroSpriteFlyAction];

    [_heroSpriteSheet addChild:_heroSprite];

    return self;
}

如果我不清楚，请原谅我，所以让我知道我需要提供的任何其他信息。现在发布这个因为我不知道还有什么地方可以解决它以及我应该提供什么其他信息，而且其他一些cocos开发者可能很明显我发布的内容有什么不对。感谢

Answer 1

模拟器可以比设备更宽容。仔细检查您的文件名是否真的是“heroTestSheet.png”而不是“HeroTestSheet.png”。它在您的设备上区分大小写。

Answer 2

想出来..它只是它试图使用的heroTestSheet.png在某种程度上无效。我在一个较旧的Photoshop中导出，但我不是很肯定它有什么设置。我从一个没有任何颜色管理设置的新版Photoshop再次导出它，现在它工作正常！

Answer 3

我认为您的图像未添加到项目中。

您必须将二进制文件复制到资源。

选择目标，然后选择构建阶段，然后复制捆绑资源在你的内容上添加你的图像。

我认为它会奏效。

Cocos2D立即在iPhone上崩溃但不在模拟器中崩溃
