Remove unused resources from xcode project.

xcode-remove-unused

#!/bin/sh
for f in `find Resources/Images -type f ! -name '*@2x.png' ! -name 'Default*.png'`; do
  FILENAME=`basename $f`; 
  NUSAGES=`usages $FILENAME | wc -l | awk '{print $1}'`;
  if [ $NUSAGES = 0 ]; then
    echo $f;
  fi;
done;

this is great, but I get

./xcode-remove-unused.sh: line 4: usages: command not found

for each iteration of the loop. I've never even heard of this command line tool and I can't find any references. can you help me? thanks!!!

'usages' is another helper script, from this file: https://gist.github.com/1440673

That script isn't polished or set up for reuse (has my project name hardcoded), but the intent is to search the project directories for references to a filename, then list out the files that reference it (i.e. a class file with a reference to a particular image).

Thank you so much for this! you really helped the http://joynme.com app out!

Thanks! So glad this could be helpful!
