仅在iOS应用中捆绑视网膜图像 [英] Bundling retina images only in iOS apps

问题描述

我们可以仅为iOS应用使用视网膜图像吗？应用程序是否适用于没有非视网膜图像的3GS设备。

Can we use retina images only for iOS apps? Do apps work on 3GS devices without the non-retina images.

请帮助我？

提前致谢。

推荐答案

iOS应用程序所需的唯一非视网膜图像是图标和默认图像。

The only non-retina images needed for an iOS app is the icon and the default image.

-app图像，只能捆绑视网膜版本并让非视网膜设备缩小它们。我已经有几次自己完成了这项工作，以达到App Store上的蜂窝网络下载限制，因此我从未被拒绝过。

For all in-app images, it's fine to bundle retina versions only and let non-retina devices scale them down. I've done it myself on a few occasions to get below the cellular network download limit on App Store and I've never been rejected because of that.

当然，由于所需的缩小操作，不提供非视网膜图像可能会降低旧设备的性能和图像质量，但如果您确实需要减小应用程序大小，这可能会很好。

Of course, not providing non-retina images may decrease performance and image quality on older devices due to the required down-scale operations, but that may be fine if you really need to decrease the app size.
