我刚刚看到iPhone 5的公告，它说像素分辨率已更改为1136 * 640，从而影响了应用程序的ASPECT RATIO。
我应该如何在我的 Cocos2d 游戏中处理这个问题？我为“旧”的 960*640 视网膜显示屏完成了所有图形，我猜这些图形在 iPhone 5 屏幕上会失真。
我对吗？或者是否会显示“旧分辨率”图像而不修改纵横比并留下一些屏幕黑色？
编辑：有没有办法让 Cocos2d 检测它是否是 iPhone 5，在这种情况下，在屏幕顶部（顶部 960 像素）绘制背景文件，并在剩余像素中绘制一些其他自定义背景文件（例如，这些可能是我们的游戏中仅适用于 iPhone 5 的一些自定义广告横幅或一些额外按钮）。
今天早上我刚刚为我的应用添加了 4 英寸的支持。Cocos2d 运行良好（在模拟器中），无需修改。我的所有场景都已正确调整大小，我只需要对某些位置进行一些修改，因为它们是固定坐标而不是相对坐标。
目前没有办法轻松加载不同的图像，我怀疑未来几天会有一个类似于 -hd 的新命名约定。
至于您的编辑问题，您可能会发现，一旦启用 4 英寸模式，您的布局顶部就会有很大的黑色空间。当然你可以放任何你想要的东西。
您可以使用以下方法检测它是否是高屏幕
[[UIScreen mainScreen] bounds].size.height
iOS 将自动在应用程序的两侧放置细黑条，以便与应用程序最初为以前版本的 iPhone 设计的方式保持一致
有几个消息来源报告了这一点，这是从这里。
到目前为止，由于没有可用的设备和 iOS 6，我们甚至不知道 cocos2d 是否需要或需要进行哪种修改以支持 iPhone 5。不用担心。不要假设。等着瞧。
与所有其他设备一样，将有办法检测确切的设备类型。同样，这将不得不等到我们至少获得 iOS 6。您可以加入测试计划以希望找到答案，但只要它处于测试阶段，此类信息就在 NDA 之下，您可能只能通过私人 Apple 找到开发者论坛。
COCOS2d - v2.x
用以下代码替换 CCFileUtils.h 和 .m 并在委托内添加行：[sharedFileUtils setiPhone5DisplaySuffix:@"-568h"]; // >>>>>> iPhone 5 -568h

你们所有人都提出了很好的解决方案，但会有某种命名约定，例如分别用于 ratina 显示和 iphone 5 启动图像的@2x 和 h@2x。
