Oops, I meant the button target as Kyle has already pointed out. > Incidentally, while it might be a noble goal to have your software > support OS versions all the way back to 10.6 or 10.5 Just 10.6 for x86. 10.4 for PowerPC but the PowerPC version of my app uses Carbon anyway. > Lastly, I may have lost track of things during the series of > threads we’ve had about memory management in your app, but I can’t > now understand why you don’t adopt ARC.

The actual Cocoa code in my app is really just a few kilobytes. It's not complicated at all so there is no pressure to simplify things by using ARC. If this was a huge project with lots of new code to be written, it would be a different matter, but it's really just a few lines. So it's a nice exercise for understanding manual memory management with Cocoa. Of course, I might switch to ARC sooner or later but I first like to learn and understand the old way of doing things... maybe this also helps me to appreciate ARC more once I start using it ;) -- Best regards, Andreas Falkenhahn mailto:andr...@falkenhahn.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
