iPhone是否需要高分辨率和标准分辨率的副本? [英] Is a copy of a high res and standard res required for iPhone?

问题描述

想知道iPhone Apps是否需要高分辨率和低分辨率图像.复制副本会增加文件大小，这是我需要缩减的大小.

Wondering if both a high res and low res image are required for iPhone Apps. Having a duplicate copy increases file size which is something I need to cut down.

我过去曾经构建过应用程序，并且只使用了高分辨率，没有在文件名后附加@ 2x.这些应用程序在低分辨率和高分辨率设备上看起来都很棒.所以...

I've built apps in the past and only used high res, without @2x appended to the file name. The apps look great on Low res and High res devices. so...

让我知道

推荐答案

不需要同时具有两种图像类型.但是，由于Retina显示屏的分辨率不同，因此您可以构建一个默认图像，该图像在iPhone 4上看起来不错，显示很多细节，但由于缺乏正确的分辨率，在其他iPhone上看起来会有所不同.此外，该图像将被降采样，并且如果您的UI恋物癖足够大，您宁愿提供两张图像，也不能只提供两张非常好的图像，并拍摄一张 capable 采样图像.

It is not required to have both image types. However, since the resolution is different for the Retina display you might build a Default image that looks nice on the iPhone 4 showing lot of details, but will look different on the other iPhones due to lack of correct resolution. Furthermore the image will be downsampled and if your UI fetish is big enough you rather provide two images than only one very good and take an accaptable sampled image.

我不确定是否仅跳过一个图像以减小文件大小是否是最好的方法，因为在大多数情况下，默认图像不是最相关的媒体部分，因为图标，声音文件等倾向于占用更多空间

I'm not sure if it is the best approach to skip one image just to reduce file size because most of the time the Default images are not the most relevant media part, since icons, sound files etc tend to use more space.

总结:我建议同时使用这两个图像，并尝试在其他地方减小App的大小.

To conclude: I would suggest using both images and try to reduce the App size somewhere else.
