如何在iPhone 4,4s和iPhone 5,5c，5s中处理图形

Question

So early when working with iPhone Retina and non-Retina, I used to handled images as "image.png" and "image@2X.png", and that used to do the trick in handling graphics.

But what I am facing now is that I am no more building for iPhone 3,3g,3gs. That means all images are for retina now, so the question is that how to handle iPhone 5,5c,5s images. As these devices vertical resolution is more than 960 pixels.

Do I need to make two separate image sets for iPhone 4,4s and iPhone 5,5c,5s?

Answer 1

不，您不需要为iPhone 4和iPhone 5系列制作两个单独的图像集，这仅是在某些背景下要拥有整个屏幕图像的情况下才需要解决的……仅针对开始屏幕使用不同的图像。

Answer 2

Edit:

icons and non-full screen graphics are probably the same on iPhone 4 & 5. For full screen wallpapers you need separate sets for different resolutions based on device here are the naming conventions you can use

image.png -> iPhone (non-retina)
image@2x.png -> iPhone 4s/4 (retina)
image-568h@2x.png -> iPhone 5
image~ipad.png -> iPad (non-retina)
image@2x~ipad.png -> iPad (retina)
