iOS SDK是否提供队列和堆栈？ [英] Does the iOS SDK provide queues and stacks?

问题描述

我正在编写一个iPhone应用程序，我很惊讶Apple中似乎没有NSQueue或NSStack类基础框架。我看，这将是很容易推出自己的，开始用的 NSMutableArray ，所以我会这样做，除非我错过了什么。我错过了什么吗？

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?

推荐答案

据我所知，没有通用类avaialbe。尝试使用NSMutableArray，通过addObject添加并通过objectAtIndex和removeObjectAtIndex获取第一个/最后一个。

as far as I know there is no generic class avaialbe. Try using the NSMutableArray, add via addObject and get first/last via objectAtIndex and removeObjectAtIndex.
