如何将一个值与多个值进行比较 - Swift [英] How to compare one value against multiple values - Swift

问题描述

假设你有代码

if stringValue == "ab" || stringValue == "bc" || stringValue == "cd" {
    // do something
}

有没有办法缩短或美化这个条件(最好不使用switch语句)?我知道此代码不起作用:

Is there a way to shorten this condition or beautify it (preferably without using the switch statement)? I know that this code does NOT work:

if stringValue == ("ab" || "bc" || "cd") {
    // do something
}

我在其他语言上看到了一些复杂的解决方案，但它们似乎是特定于语言的，不适用于 Swift.任何解决方案将不胜感激.

I've seen some complex solutions on other languages, but they seem language specific and not applicable to Swift. Any solutions would be appreciated.

推荐答案

let valuesArray = ["ab","bc","cd"]

valuesArray.contains(str) // -> Bool
