领域-Swift存储协议类型 [英] Realm - Swift store a protocol type

问题描述

我具有以下结构:

class Entity : Object {
    dynamic var Id = 0
    dynamic var Title = ""
    dynamic var Subtitle = ""
    var atttribute : MyProtocol?

}

是否可以在属性中存储某些内容? 今天返回零.如果添加动态，则会返回错误:

Is there a way of storing something in attribute? Today is returning nil. If I add dynamic it returns the error:

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

有什么方法可以存储符合协议的属性吗?

Is there any way to store properties that conform to a Protocol as that?

推荐答案

否.领域属性是单态的，领域需要知道在初始化时将链接到的具体对象类型是什么.

No. Realm properties are monomorphic, and Realm needs to know what the concrete object type that will be linked to is at initialization time.
