是否可以在RealmSwift中使用枚举? [英] Is it possible to use enums in RealmSwift?

问题描述

我想做这样的事情:

enum WeekDay {
    case Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday
}

class Person: Object {

    dynamic var birthday: WeekDay? = .Monday
    dynamic var id: String? = nil
    dynamic var birthdayRaw: String? = nil

    override static func primaryKey() -> String? {
        return "id"
    }
}

但是，我遇到一个错误:

But, I'm getting an error:

由于属性的类型不能为动态，因此无法将其标记为动态 代表在Objective-C

Property cannot be marked dynamic because its type cannot be represented in Objective-C

我该如何解决?感谢您的帮助.

How can I solve this ? Thanks for any help.

推荐答案

领域没有直接的方法. Github问题.

Realm doesn't have a direct way do it. Github issue.

但是你可以考虑这个技巧

But you can consider this trick

enum WeekDay: String {
    case Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday
}

class Person: Object {
    private var _day: WeekDay?
    var birthday: WeekDay? {
        get {
            if let resolTypeRaw = birthdayRaw  {
                _day = WeekDay(rawValue: resolTypeRaw)
                return _day
            }
            return .Sunday
        }
        set {
            birthdayRaw = newValue?.rawValue
            _day = newValue
        }
    }

    dynamic var id: String? = nil
    dynamic var birthdayRaw: String? = nil

    override static func primaryKey() -> String? {
        return "id"
    }
}
