如何在 Swift 中将类名指定为变量? [英] How do I specify class name as variable in Swift?

问题描述

我想做这样的事情:

class Dog: Object {
  dynamic var name = ""
  dynamic var age = 0
}

let results = realm.objects(Dog)

...但将对象名称指定为变量.

...but specify the object name as a variable.

这不起作用:

let objectName = "Dog"
let results = realm.objects(objectName)

这两者都没有:

let object = Dog
let results = realm.objects(object)

...或者这个:

let object = Dog()
let results = realm.objects(object)

...或者这个:

let object: Dog
let results = realm.objects(object)

有什么想法吗?

推荐答案

可以直接用Dog.self引用类型:

let type = Dog.self

我没有 Realm 的项目，但理论上你应该能够执行以下操作:

I don't have a project with realm, but in theory you should then be able to do something like:

let results = realm.objects(type)
