typedef作为Core数据类型 [英] typedef as a Core data type

问题描述

我正在建立一个核心数据模型，我的一个类需要一个变量，最好实现为typedef。现在我实现它作为一个字符串变量，它接受三个可能的值，但是当然这是不健壮的。

有一种方法来实现这个在Core Data模型？

解决方案

您可以有未定义类型的整数属性和transcient属性，根据整数属性值初始化

I am building a Core Data model and one of my classes needs to have a variable that can best be implemented as a typedef. Right now I am implementing it as a string variable that takes three possible values, but of course this is not robust.

Is there a way to implement this in the Core Data model?

解决方案

You can have integer attribute and transcient attribute of undefinied type which is initialized depending on the integer attribute value?
