What is?

Scripts to automatically generate iOS icons and launch images in the correct sizes. Also contains optimal asset catalogs with reused images for identical sizes.

Tested with Xcode 5,6 and iOS 6-8.

No dependencies.

Usage

Default-Input.png and Icon-Input.png contain the initial graphics for the launch image and icons respectively.

From Terminal run:

./CreateiOSLaunchImagesPortrait.sh --padColor F9782C

--padColor specify padding color, other possible parameters may be found here: https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/sips.1.html

and

./CreateiOSIcons.sh

and

./CreateiOSToolbarNavigationIcons.sh

to create all necessary size variants.

Optional

Remove variants that are not needed (e.g. iPad Portrait) from the catalogs to optimize app size.
