With the iPad and iPhone 4, there are as many, if not more, different size icons to create for iOS than there are for desktop apps. While there are plenty of templates and reference sheets for Photoshop users (see Cocoia) I prefer to use Illustrator CS5 to create mine. So I’ve made my own template, and it’s available here if you find it useful too!
The top layer of the file contains labels and a mask to add the rounded corners of the icon. Don’t forget to hide these before you export.
Something that Apple doesn’t include in it’s documentation are the various corner radius dimensions for all the icon sizes. This information has been compiled thanks to investigations of Sarah Parmenter and Tim Van Damme.
It’s best to create the artwork with 90° corners and let the OS round them off, but there is a mask layer to help you check how it would look. The mask also uses the appropriate colour for the context – white for the app store, black for the home screen and light grey for the spotlight results.
Also the icon that iOS uses for spotlight results on the iPad is trimmed by 1px around the edge. So while the artwork still needs to be supplied as 50px, the visible area is only 48px, and the guides reflect that, while the rounded corner mask stays at 50px.
The icons are all set out on their own artboard, so when you’re ready to export check the ‘Use Artboards’ option to get each icon as an individual file:
While I’ve worked hard to make sure this template is as accurate as possible, I can’t guarantee it’s completely error-free. Let me know if you find any bugs, and I’ll update it!
If you’re using CS4 or below, this template may well work for you, but hasn’t been tested and may explode leaving terrible stains. I target CS5 because of it’s the first version that has pixel snapping that actually works!
