我的应用程序在模拟器和其他设备上运行良好。我有一部带有最新 iOS 更新的 iPhone 4，但该应用程序拒绝在我的设备上运行。

这似乎是围绕视网膜显示图像的问题。尝试在手机上运行时出现的错误是：

奇怪的是，它吐出的图像在应用程序中。

资源目录截图

同样，该应用程序适用于其他设备和模拟器。这是加载图像的代码：

backgroundNode = [CCParallaxNode node];
[self addChild:_backgroundNode z:-1];

_backgroundGrid1 = [CCSprite spriteWithFile:@"grid.png"];
_backgroundCircuits1 = [CCSprite spriteWithFile:@"bg-circuits.png"];

_backgroundGrid1.anchorPoint = CGPointMake(0,0);
_backgroundCircuits1.anchorPoint = CGPointMake(0,0);
CGPoint gridSpeed = ccp(0.05, 0.05);
CGPoint circuitSpeed = ccp(0.1, 0.1);

[_backgroundNode addChild:_backgroundGrid1 z:1 parallaxRatio:gridSpeed positionOffset:ccp(0,-winSize.height)];
[_backgroundNode addChild:_backgroundCircuits1 z:0 parallaxRatio:circuitSpeed positionOffset:ccp(0,-winSize.height)];

我已经从手机中删除了该应用程序，运行“干净”，重新启动 Xcode，然后重新启动计算机。仍然没有运气。我也重新配置了我的手机。我还删除了资产并将其重新添加到项目中。

老实说，在您的日志文件中确实表明 1024 x 4096 的图像大小远远大于支持的 2048 x 2048：

2012-01-11 09:27:48.031 rr_game1[1569:707] cocos2d: WARNING: Image (1024 x 4096) is bigger than the supported 2048 x 2048

您说它可以在其他设备上运行，但它们是什么设备？如果它们没有启用视网膜，我想各自的图像尺寸将是 512x2048，因此适合 2048x2048 的最大尺寸。

如果您的视网膜显示图像超出了这些尺寸，它将无法正常工作 - 2048x2048 应该已经包含了视网膜大小的图像。您可能需要修改游戏以使用更小的尺寸。

您真的应该考虑将图像切割成更小的块，并可能将它们放在精灵表中以提高性能。然后，您可以使用类似这样的方法简单地将图像切片彼此相邻添加

    for (int i = 0; i < amountOfSprites; i++){
        CCSprite *sprite = [CCSprite spriteWithSpriteFrameName:spriteName];
        sprite.anchorPoint = ccp(0,0);

        sprite.position = ccp((i * sprite.contentSize.width),0);


        [yourBatchNode addChild:sprite];
    }

如果您在创建精灵表方面需要任何帮助，请查看本指南http://www.raywenderlich.com/2361/how-to-create-and-optimize-sprite-sheets-in-cocos2d-with-texture-packer-and -像素格式
