如何排序斯威夫特/ X code 1阵列，并使用相同的按键重新排列变化等多重阵列 [英] How to sort 1 array in Swift / Xcode and reorder multiple other arrays by the same keys changes

问题描述

对不起，这个问题的复杂的措辞。我的主要经验是用PHP，它有一个名为在array_multisort命令。语法如下：

Sorry for the complex wording of the question. My main experience is with PHP and it has a command called array_multisort. The syntax is below:

bool array_multisort ( array &$array1 [, mixed $array1_sort_order = SORT_ASC [, mixed $array1_sort_flags = SORT_REGULAR [, mixed $... ]]] )

它可以让你排序1阵列和基于原有的关键变化重新排序其他多个阵列。

It lets you sort 1 array and the reorder multiple other arrays based on the key changes in the original.

是否有等效的命令雨燕/ X code 7.2？

Is there an equivalent command in Swift / Xcode 7.2?

我现在有一个阵列集：

名字
年龄
市
国家
主动

FirstName Age City Country Active

活动是一次用户已我的应用程序内的活跃秒的数组。我想下令升序或降序和其他阵列更改为保持一致。

Active is an array of time in seconds that a user has been active within my app. I would like to order that descending or ascending and the other arrays to change to remain consistent.

推荐答案

您可以创建有序索引的数组，并把它作为一个映射：

You could create an array of indexes in sorted order and use it as a mapping:

var names = [ "Paul", "John", "David" ]
var ages  = [  35,    42,     27 ]

let newOrder = names.enumerate().sort({$0.1<$1.1}).map({$0.0})

names = newOrder.map({names[$0]})
ages  = newOrder.map({ages[$0]})
