How to generate different sizes of icons from .psd?

Question

iOS app needs different sizes of icons to fit different screens, so after we design an icon with psd format, we will have to generate many icons(29px*29px,40px*40px,...), which is a tedious task.

How to batch generate them at a time?

Answer 2

If you have Photoshop CC you can generate image assets from Layers .

For example if you set this name to a Layer :

29px x 29px icon29x29.png, 40px x 40px icon40x40.png, 128px x 128px icon128x128.png

Will generates these image assets:

• icon29x29.png
• icon40x40.png
• icon128x128.png

With these specific sizes.
