arrays - 在 Swift 中订购二维数组

Question

我尝试找到任何解决方案，但我找不到。

在 Swift 4 中，我有下一个数组:

[ ["839", "Huergo"], ["733", "Lavaisse"], ["732", "Pedro De Vega"]  ["824", "Obispo Boneo"],["727", "Hernandarias"], ["741", "Padre Genesio"], ["852", "Obispo Principe"]]

我需要按第二列的字母顺序排序，并作为最终数组获取:

[["727", "Hernandarias"], ["839", "Huergo"], ["733", "Lavaisse"], ["824", "Obispo Boneo"], ["852", "Obispo Principe"], ["741", "Padre Genesio"], ["732", "Pedro De Vega"]]

谢谢!

Answer 1

你可以简单地这样做:

let sortedArray = array.sorted { $0[1] < $1[1] }

看看 documentation sorted(by:) 方法，它说:

Returns the elements of the collection, sorted using the givenpredicate as the comparison between elements.
