在swift 2.0上反映属性值 [英] reflect property value on swift 2.0

问题描述

如何在Swift 2.0上获取属性值? 在swift 1.0上，我可以按值属性获取Mirror值，但是我找不到API可以做到这一点. swift 2.0上的New Mirror类型只有很少的api.还有其他方法可以实现这一目标吗?

how can I fetch the property value on swift 2.0? on swift 1.0, I can get the Mirror value by value property, but I cannot find an API do this. New Mirror type on swift 2.0 only has few api. Is there any other way to achieve this?

推荐答案

这是反射速度为2的用法.

This is the usage of reflection is swift 2.

let mirror = Mirror(reflecting: obj)
for child in mirror.children {
    guard let key = child.label else {
        continue
    }
    let value = child.value

    // use value or key here
}
