The other day a colleague and I were trying to remember how to get the icon art for iOS apps to help write notes. We though we remembered a way to get them out from examining the package. Later I was reading the ADE list, where there was a bit of bemoaning that you can no longer copy the art from iTunes. Someone mentioned that the art was now is a file iTunesArtwork inside the .ipa files in the iTunes folder, the .ipa file being zip files.
This means you can get the art work by, changing the extension on an ios app file to .zip, expanding the archive, adding a .png extension to the iTunesArtwork file. You end up with the artwork png file.
This seems like a fairly long road for a short cut. A wee bit of though lead me to try a few shell scripts. Basically you can use the unzip command to extract the iTunesArtwork file with a png extension and you get a png file of the artwork.
To make this a little easier I wrapped up the shell script in an AppleScript. Drag a bunch of .ipa files onto the droplet and it will create a folder on your desktop and extract the art work as png files. Double click the droplet and it will prompt you for a file and do the same. The files are named the same as the .ipa files except I replace all non alphanumerical characters with an underscore. I’ve put the script in my dropbox in case anyone would find it useful, and uploaded the text so you can View the Script.
BTW: Rounded Corners
So the artwork extracted does not have the rounded corners:
You can change the way that looks on the web with a bit of css:
style="-moz-border-radius: 20%;-webkit-border-radius: 20%;border-radius: 20%;"
This might help other folk documenting iOS stuff. I’ve now got a folder of >600 icons ready to go.
