如何在swift中获取枚举的所有值[重复]

Question

假设我有以下代码：

enum Suit {
    case Spades, Hearts, Diamonds, Clubs
}

是否有一种方法可以得到下面的数组？

[Spades, Hearts, Diamonds, Clubs]

Answer 1

我不知道有没有办法做到这一点。这是一个很好的问题，希望有人能找到另一种方法，多通用的我。不管怎样，我做了一些事情

这里是枚举：

// SuitCount is the last one, so the total of elements (used) is SuitCount-1
enum Suit: Int {
    case Spades, Hearts, Diamonds, Clubs, SuitCount
}

返回值的函数：

func getValueFromSuitAtIndex(#indexOfElement: Int) -> String {

     var value = ""

     switch indexOfElement {
     case 0:
        value = "Spades"
     case 1:
        value = "Hearts"
     case 2:
        value = "Diamonds"
     case 3:
        value = "Clubs"
     default:
        value = ""
     }   

     return value
}

var suitElements = String[]()
for index in 0...Suit.SuitCount.toRaw()-1 {
    suitElements.append(self.getValueFromSuitAtIndex(indexOfElement: index))
}
// suitElements printed is: [Spades, Hearts, Diamonds, Clubs]
println(suitElements)
