I know you can use C++ in objective C. But I was looking for a guide that does a comparison of syntax and libraries (the bascis and STL). I looked a bit online and couldn't find a very good cheat sheet. I saw this post here: http://forums.macrumors.com/showthread.php?t=338244 but its not very comprehensive and the some of the links are dead. Any one know of a really good reference for this? I meant cocoa. I am working in cocoa. trying to develop a mac app.
