Swift利用反射获取对象属性列表

Objective-C中获取类(类对象)的属性列表利用runtime
Swift可以利用反射获取

class SuperClass: NSObject {
    var name:String = "zym_chen"
    var qq: String = "625271562"
}

class SubClass: SuperClass {
    var age:Int = 1
    var sex:Bool = true
    
    class func test() {
        let obj: SubClass = SubClass()
        let morror = Mirror.init(reflecting: obj)
        let superMorror = Mirror.init(reflecting: obj).superclassMirror

        for (name, value) in (superMorror?.children)! {
            print("父类属性名:\(name) 值: \(value)")
        }
        for (name, value) in (morror.children) {
            print("子类属性名:\(name) 值: \(value)")
        }
    }
}

// 打印结果:
父类属性名:Optional("name") 值: zym_chen
父类属性名:Optional("qq") 值: 625271562
子类属性名:Optional("age") 值: 1
子类属性名:Optional("sex") 值: true

比起用runtime要方便, 而且可以分别获取对象仅属于自身的属性值和从父类继承的属性值.不过暂时Swift中反射的功能远还没有runtime强大
