I'm writing an iPhone app, and I'm surprised that there seem to be no NSQueue or NSStack classes in Apple's Foundation Framework. I see that it would be quite easy to roll my own, starting with an NSMutableArray, so I'll do that unless I've missed something. Have I missed something?

Yes, an NSMutableArray doubles as a stack or queue. (It would be slightly inefficient as a queue.)
You could also use C++'s
stackandqueueadapter, but it makes memory management a bit messy if you want to store Objective-C objects with it.
