在swift中将枚举值获取为Int

如何在swift中获取枚举Int值

创建枚举

enum FriendActionType:Int {    
    case sendFriendRequest = 1, cancelFriendRequest, acceptFriendRequest, removeFromFriendList, deleteFriendRequest
}

打印时不使用哈希完美传递变量

po "\(friendActionType)"
"deleteFriendRequest"

打印哈希值日志打印错误的int值“-1188319181990702728”而不是“5”

po friendActionType.hashValue
-1188319181990702728

我需要枚举变量的Int“5”值。

使用friendActionType.rawValue

rawvalue示例

 enum Planet: Int {
        case mercury = 1, venus, earth, mars, jupiter, saturn, uranus, neptune
    }
    let earthsOrder = Planet.earth.rawValue
    // earthsOrder is 3

使用friendActionType.rawValue

 enum Planet: Int {
        case mercury = 1, venus, earth, mars, jupiter, saturn, uranus, neptune
    }
    let earthsOrder = Planet.earth.rawValue
    // earthsOrder is 3

不要混淆hashValue和rawValue。@rmaddy确定得到它：print friendActionType.rawValue不要混淆hashValue和rawValue。@rmaddy确定得到它：print friendActionType.rawValue
