swift - 如何比较相同枚举的值？ (== 比较不起作用!)

Question

Answer 1

这对我有用:

enum CompassPoint {
    case North
    case South
    case East
    case West
}

let isEqual = CompassPoint.North ==  CompassPoint.South
//false

另一个例子:

enum CompassPoint: Int {
    case North = 1, South, East, West
}

let isEqual = CompassPoint.North ==  CompassPoint.South
//false

这也适用:

enum MyEnum {
    case SomeValue
    case OtherValue
    case ThirdValue
}


let areEqual = MyEnum.ThirdValue == MyEnum.ThirdValue

但您的示例枚举具有不同的类型。您将只能比较分配给他们的各种。
