Does the iOS SDK provide queues and stacks?

Question

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 m

Answer 1

Yes, an NSMutableArray doubles as a stack or queue. (It would be slightly inefficient as a queue.)

You could also use C++'s stack and queue adapter, but it makes memory management a bit messy if you want to store Objective-C objects with it.

Answer 2

ObjectiveSugar is a very popular CocoaPod that provides, among a bunch of other great stuff, push and pop API calls on NSMutableArray. Sure, it's not in the iOS SDK, but I'm sharing it here because I was looking for the same thing, and this was the solution I went with (and it certainly didn't hurt that we were already using this CocoaPod in our codebase).
