提问by Red Mak
i have a Mac with Mac OS X Snow Leopard, can i add iOS 5.1 to it?
我有一台装有 Mac OS X Snow Leopard 的 Mac，我可以向它添加 iOS 5.1 吗？
With the new resolution for iPad 3, how we will do with images, because if the app will run in iPhone 3GS, 4 and iPad 3 i think we should have 3 images with different name like @3x.png or .. thank you.
使用 iPad 3 的新分辨率，我们将如何处理图像，因为如果应用程序将在 iPhone 3GS、4 和 iPad 3 中运行，我认为我们应该有 3 个不同名称的图像，例如@3x.png 或 .. 谢谢。

iOS 5.1 comes with Xcode 4.3.1 which is only available for Lion —?the only download available in the Developer section on Apple's Developer portal for iOS 5.1.
iOS 5.1 随附 Xcode 4.3.1，它仅适用于 Lion — 这是 Apple 的 iOS 5.1 开发人员门户的开发人员部分中唯一提供的下载。
Basically, the iPad images are going to be double the size of the image you would normally create for the iPad. For instance:
基本上，iPad 图像将是您通常为 iPad 创建的图像大小的两倍。例如：
Launch images
iPhone:: 320 x 480
iPhone @2x:640 x 960
iPad:768 x 1004 (portrait), 1024 x 748 (landscape)
iPad @2x:1536 x 2008 (portrait), 2048 x 1496 (landscape)

And be sure to restart Xcode.

You will need 4 resolutions most likely for some items and 2 for others.
对于某些项目，您很可能需要 4 个分辨率，而对于其他项目则需要 2 个分辨率。

You only need these if you're scaling up the resolution if the old graphic for retina iPhone works you probably want to use that for your iPad UI. Specifics like app icons are a different beast and you will need 4.
如果 Retina iPhone 的旧图形可以工作，您只需要在放大分辨率时才需要这些，您可能希望将其用于 iPad UI。应用程序图标之类的细节是不同的野兽，您将需要 4。
