I tend to agree. I went through a similar exercise with an OSX app. The ARCified code runs fine and there appears to be only one minor leak (I think it's in Apple's own code). One minor fly in the ointment -- ARC only works with Intel 64-bit apps and only on OSX 10.6 and 10.7. If you want to support earlier OS versions you need to build a separate app. Jim Merkel _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
