I am not finding a straight forward site with the iOS8 sizes and names for the app icons and launch image.
I have seen the iOS Human Interface Guidelines but they don\'t
Autogenerate all necessary icon and launch image files (iOS 7 and above) with the following scripts:
http://github.com/spren9er/s9icongen
http://github.com/spren9er/s9splashgen
When the script is executed all sizes and names will be displayed in the console, e.g. for launch images
320x480(2x) -> 640x960: Default@2x~iphone.png
320x568(2x) -> 640x1136: Default-568h@2x~iphone.png
375x667(2x) -> 750x1334: Default-667h@2x~iphone.png
414x736(3x) -> 1242x2208: Default-736h@3x~iphone.png
