ios - 如何在 swift 中从枚举成员原始值创建数组字符串

Question

我是编程新手，而且速度很快。我有一个这样的枚举

enum City : String {
    case tokyo = "tokyo"
    case london = "london"
    case newYork = "new york"
}

我能否从枚举原始值中获取城市名称到数组？我希望我能得到这样的东西:

let city = ["tokyo","london","new york"]

Answer 1

像这样。

let cities = [City.tokyo, .london, .newYork]
let names = cities.map { $0.rawValue }
print(names) // ["tokyo", "london", "new york"]

获取所有枚举值作为数组see this .
