ObjectiveC - 键值对集合与重复的键 [英] ObjectiveC - Key-Value-Pair Collection with duplicate Keys

问题描述

ObjectiveC提供了键值对的集合，允许键多次出现？

Does ObjectiveC provide a collection for Key-Value-Pairs, that allow a key to occur multiple times?

我尝试将xml文件解析成一些简单的结构。每一件事都已经在使用嵌套的NSDictionary，但现在的xml元素可以多次出现。

I try to parse a xml file into some simple structure. Every things is already working with nested NSDictionary, but now xml elements can occur multiple times.

编辑：我的解决方案

我选择一个NSArray与KeyValuePairs，结果，我需要一个是秩序敏感，NSDictionary是不可能的。副作用：NSFastEnumeration很容易实现这种方式为我的集合。

I choose an NSArray with KeyValuePairs, it turned out that I need something that is order sensitive, NSDictionary was not possible. Sideeffect: NSFastEnumeration is easy to implement this way for my collection.

推荐答案

不，Cocoa没有这样的集合。如果你不想使用第三方库，你可以使用 NSDictionary 与 NSArray 值。或者，您可以查看 CHDataStructures 框架。

No, Cocoa doesn’t have such a collection. If you don’t want to use a third-party library for that you can simulate that by using a NSDictionary with NSArray values. Or you could take a look at the CHDataStructures framework.
