IOS 5中有没有有序的字典集合？ [英] Is there any ordered dictionary collection in IOS 5?

问题描述

我的问题是我使用的表数据源从字典。这个字典包含超过20个元素。

My issue is I am using the table data source from the dictionary. This dictionary contains more than 20 elements in it.

我需要搜索字典中的元素，我需要滚动该元素到一个可见的单元格。

I need to search the element present in the dictionary and I need to scroll that element to a visible cell.

我的问题是我找到了元素，但它是在可见区域之外。

My issue is I found the element, but it is out of the visible area. I need to scroll that to a visible area.

如何获取索引？

更长的答案？是啊？我的搜索稍后会带我到这个可爱的小页面。这家伙为有序字典提供了一个漂亮，简洁的小类。我建议阅读完整的文章，它解释很好。

Longer answer? Yes-ish? My search a little while back brought me to this lovely little page. The guy provides a nice, neat little class for an ordered dictionary. I suggest reading the full article, it explains things nicely.

基本的要点是它同时维护一个NSMutableArray和一个NSMutableDictionary，使用数组索引，和键的字典。非常简单，真的。

The basic gist is that it maintains both an NSMutableArray and an NSMutableDictionary at the same time, using the array for indices, and the dictionary for keys. Quite simple, really.
