Do you really mean /Library/Cache, or do you mean ~/Library/Cache (the application's cache directory). You generally have no control over the former, so I'll assume you mean the latter.

Use NSFileManager's -enumeratorAtPath: to walk the directory and use -attributesOfItemAtPath:error: to fetch the fileSize. I recommend doing this slowly on a background thread to avoid blocking your app.
