我正在 iPhone 中使用 Cocos2d 和 Objective-C 创建一个通用游戏。我的项目几乎完成了。我在控制台窗口的运行时收到此错误。

对于 iPhone4.3 模拟器和 iPhone (Retina)，Game 运行良好。

仅当我选择“iPad”模拟器执行时才会出现此错误。

有任何想法吗？我对此感到非常困惑..提前致谢！

它告诉你这里的问题。您正在尝试加载超出 iPad 可以支持的最大尺寸的图像，因此 cocos2d 无法加载它。当您尝试将其添加为 a 时，CCSprite您会触发非手动NSInternalInconsistencyException操作（因为节点是nil），这会导致您的应用程序终止。

对于 iPad，您需要使用较小的图像。
