详解Swift model 解析的两种方法

import Foundation 
 
class LJNewsModel: NSObject { 
   
  //MARK:- 定义属性 
  var imgsrc: String = ""  ///< store user's name, optional 
  var title: String = ""   ///< store user's telephone number 
  var replyCount: Int = 0 
   
   //方法一的model 
  //MARK:- 自定义构造函数 
  init(_ dict : [String: Any]){ 
    super.init() 
    setValuesForKeys(dict) 
  } 
 
  override func setValue(_ value: Any?, forUndefinedKey key: String) { 
  } 
}
