问题描述

我有一个(应用程序版本的)字符串数组,它们的排列顺序如下:

I have an array of strings (of an app's versions) randomly ordered like:

var arrayOfStrings = ["2.12.5", "2.12.10", "2.2", "2.11.8"]

已排序数组应为[ 2.2, 2.12.10, 2.12.5, 2.11.8](按最新顺序排列)。我正在尝试对它进行排序。

The sorted array should be ["2.2", "2.12.10", "2.12.5", "2.11.8"] (ordered by most recent). I am trying to sort it.

编辑:我不好,排序后的数组实际上应该是[ 2.12.10, 2.12.5, 2.11.8 , 2.2]。使用上面的解决方案。

My bad, the sorted array should actually be ["2.12.10", "2.12.5", "2.11.8", "2.2"]. Use the solution above.

//Compare by string
array.sortInPlace({ //This returns ["2.2", "2.12.5", "2.12.10", "2.11.8"]
    $0 > $1
})

//Compare by int
array.sortInPlace({ //This returns ["2.12.10", "2.12.5", "2.11.8", "2.2"]
    Int($0.stringByReplacingOccurrencesOfString(".", withString: "")) > Int($1.stringByReplacingOccurrencesOfString(".", withString: ""))
})

没有一个工作正常。返回正确数组的最佳方法是什么?

None of this is working properly. What is the best way to return the correct array?

推荐答案

最简单的选择是使用 compare .NumericSearch

The easiest option is to use compare with .NumericSearch:

arrayOfStrings.sortInPlace { $0.compare($1, options: .NumericSearch) == .OrderedAscending }

很明显,如果您想要按降序排列,请使用 .OrderedDescending

Obviously, if you want it in descending order, use .OrderedDescending.
