I, too, prefer the approach of sticking with the NSLog signature and using __OPTIMIZE__ that I first found at this post’s predecessor (which was here, for searchers to find: http://www.marekbell.com/Marek_Bell/Blog/Entries/2009/3/25_Removing_NSLogs_on_Release_Builds.html), which has vanished from the caches. Thanks for re-sharing!
