如何在Swift中使用另一个数组中的元素过滤数组? [英] How To Filter Array Using Element in Another Array in Swift?

问题描述

我有两个数组

let toBeFiltered = ["star0", "star2", "star1", "star0", "star3", "star4"]
let theFilter = ["star1", "star3"]

如何使用第二个数组过滤第一个数组?实际上theFilter可以动态更改，例如

How to filter the first array using the second array? Actually the theFilter can be changed dynamically, e.g,

let theFilter = ["star2"]
or maybe
let theFilter = ["star0", "star4", "star2"]

感谢您的帮助:)

推荐答案

使用设置操作

Set(toBeFiltered).intersection(Set(theFilter))
