获取自定义ns对象的属性数组的简单方法?

穴居人之道:

public class Contact: NSObject {

  var first: String = ""
  var last: String = ""
  var title: String = ""

  var values: [String] {
    return [first, last, title]
  }
}

一种更有用的方法,它允许您序列化到nskeyedarchiver、jsonencoder或其他:

public class Contact: NSObject {

  var first: String = ""
  var last: String = ""
  var title: String = ""

  var values: NSDictionary {
    return [
      "first": first,
      "last": last,
      "title": title
    ]
  }
}

不管是哪种方式,最简单的方法是手动删除您感兴趣的状态属性。

找到对象属性值的最佳方法是使用apple提供的镜像api。您可以获取属性值

示例代码

public class Contact: NSObject {
var first: String = ""
var last: String = ""
var title: String = ""
//and so forth

var values: [String] {
    return Mirror(reflecting: self).children.map {$0.value as? String ?? ""}
}
