Where is the 1024x1024 app icon used?
提问by Ben Packard
Apple now require that a 1024x1024 icon is submitted for the App store. Where can I see an example of where this icon is used? The largest icon I can find in the iTunes store is about 180x180 - even on a retina screen, 360x360 would be sufficient.
Apple 现在要求为 App Store 提交 1024x1024 图标。在哪里可以看到使用此图标的示例？我在 iTunes 商店中能找到的最大图标大约是 180x180 - 即使在视网膜屏幕上，360x360 也足够了。
I am putting some time into designing a large version of my icon, but if it is going to then be shrunk down, I need to design for this, no?
我正在花一些时间来设计我的图标的大版本，但如果它要缩小，我需要为此设计，不是吗？

The large version of the icon is used to generate smaller versions for display in the app store and in other places that require icons in sizes other than the ones you submit. That way, if they need a version of your icon that's 162 px square, or 204 px square, or whatever, they have plenty of pixels in the larger version to ensure a reasonable rendition at smaller size.
大版本的图标用于生成较小的版本，以便在应用程序商店和其他需要使用您提交的尺寸以外的图标的地方显示。这样，如果他们需要一个 162 px 正方形或 204 px 正方形或其他大小的图标版本，他们在较大的版本中有足够的像素以确保以较小的尺寸进行合理的再现。
Apple used to require a 512 x 512 px icon for this purpose -- sounds like they've doubled the resolution to support retina displays.
为此，Apple 曾经需要一个 512 x 512 像素的图标——听起来他们已经将分辨率提高了一倍以支持视网膜显示。
Remember, we're talking about a megapixelimage here, not a 32 x 32 px tiny icon. When you're dealing with teensy icons, you do have to hand tweak each pixel to get the best approximation of the image you're trying to represent. When you're talking about scaling from 1024 px square to 360 px square, there shouldn't be a problem unless you've added some very fine detail at the large size. Don't do that.
请记住，我们在这里谈论的是百万像素图像，而不是 32 x 32 像素的小图标。当您处理很小的图标时，您必须手动调整每个像素以获得您尝试表示的图像的最佳近似值。当您谈论从 1024 px 正方形缩放到 360 px 正方形时，除非您在大尺寸上添加了一些非常精细的细节，否则应该不会有问题。不要那样做。

Starting in July, newly submitted iOS apps require high-resolution icons and cover art. Large icons and Newsstand cover art must have a minimum resolution of 1024 x 1024 pixels. To change your app icons or cover art, go to the Manage Your Applications module on iTunes Connect. For more information, see the Custom Icon and Image Creation Guidelines in the iOS Developer Library.
从 7 月开始，新提交的 iOS 应用程序需要高分辨率图标和封面艺术。大图标和报亭封面艺术的最小分辨率必须为 1024 x 1024 像素。要更改您的应用程序图标或封面，请转到 iTunes Connect 上的“管理您的应用程序”模块。有关更多信息，请参阅 iOS 开发人员库中的自定义图标和图像创建指南。
As the largest right now would be the iPad 3 retina, the icon would be used for the AppStore large icon, which used to be 512 x 512, so double that for retina.
由于现在最大的是 iPad 3 视网膜，该图标将用于 AppStore 大图标，以前是 512 x 512，是视网膜的两倍。

App icon for the App Store
App Store 的应用程序图标
I guess it is for retina and promotion purposes. So Apple can make the large banners in the store and smaller icons out of it.
我想这是为了视网膜和宣传目的。因此，Apple 可以制作商店中的大横幅和小图标。
