ios - 从存储在变量中的类型获取静态属性的内容

Question

下面的代码非常人为设计，但最重要的是我有一个包含类型的变量(例如 let someType: AnyObject = SomeClass.self)，我想获取静态的值属于存储在该变量中的类型的属性。这在 Swift 中可能吗？

class SomeClass {
    var someDict: Dictionary<String, AnyObject> = {
        "aKey": SomeOtherClass.self
        "anotherKey": SomeOtherOtherClass.self
    }

    func someFunction() {
        let someType: AnyObject? = someDict["aKey"]

        // This line is incorrect, but how would get the static value I am after?
        let aString: String = someType.someString
        println(aString)
    }
}

class SomeOtherClass {
    static var someString: String = "Hello World"
}

class SomeOtherOtherClass {
    static var someString: String = "Foo Bar"
}

Answer 1

答案是将 AnyObject 引用更改为 SomeOtherBaseClass.Type，其中 SomeOtherBaseClass 是 SomeOtherClass 和 SomeOtherOtherClass< 的父类.

class SomeClass {
    var someDict: Dictionary<String, SomeOtherBaseClass.Type> = {
        "aKey": SomeOtherClass.self
        "anotherKey": SomeOtherOtherClass.self
    }

    func someFunction() {
        let someType: SomeOtherBaseClass.Type? = someDict["aKey"]

        // This line is incorrect, but how would get the static value I am after?
        let aString: String = someType!.someString
        println(aString)
    }
}

class SomeOtherClass {
    static var someString: String = "Hello World"
}

class SomeOtherOtherClass {
    static var someString: String = "Foo Bar"
}
