Can I make a property of Realm Object from Enum data type?
所以我有如下自定义数据类型：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | enum WeightUnit : String { case Piece case Gram case Kilogram case Karton case Pouch case Dus case Renteng case Botol init (weightUnitFromServer: String) { switch weightUnitFromServer { case"Pcs": self = .Piece case"Gram": self = .Gram case"Kilogram": self = .Kilogram case"Ctn": self = .Karton case"Pch": self = .Pouch case"Dus": self = .Dus case"Rtg": self = .Renteng case"Btl": self = .Botol default: self = .Piece } } } |
并且我希望我的产品(领域对象)具有该
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | class Product : Object { @objc dynamic var productID : Int = 0 @objc dynamic var name : String ="" @objc dynamic var categoryID : Int = 0 @objc dynamic var categoryName : String ="" @objc dynamic var unitPrice: Double = 0.0 @objc dynamic var quantityInCart = 0 @objc dynamic var quantityFromServer = 0 @objc dynamic var descriptionProduct : String ="" @objc dynamic var hasBeenAddedToWishList : Bool = false @objc dynamic var hasBeenAddedToCart : Bool = false @objc dynamic var isNewProduct : Bool = false @objc dynamic var productWeight : String ="" @objc dynamic var weightUnit : WeightUnit? <--- the problem in here @objc dynamic var minimumOrderQuantity = 0 @objc dynamic var maximumOrderQuantity = 0 } |
它给出了一个错误：
Property cannot be marked @objc because its type cannot be represented
in Objective-C
1 2 3 4 5 6 7 8 9 | class Animal: Object { @objc dynamic var animalClass: String ="" var animalClassType: AnimalClass? { return Class(rawValue: self.animalClass) } } enum AnimalClass: String { case mammal, reptile } |
