详解Swift model 解析的两种方法

1. 常规解析方法

//懒加载声明一个LJNewsModel为数据的数组

lazy var ljArray : \[LJNewsModel\] = \[LJNewsModel\]()

//MARK:-- 数据获取和解析

extension NewsViewController\{

func requestNetData()\{

/\*

打印json数据

\*/

LJDownLoadNetImage.request("GET", url: "http://c.m.163.com/nc/article/list/T1348647909107/0-20.html") \{ (data, respond, error) in

方法一：解析数据

let str = String(data:data!, encoding: String.Encoding.utf8)!

print(str)

let ljTempArray : NSArray = self.getDictionaryFromJSONString(jsonString: str).object(forKey: "T1348647909107") as! NSArray

for m in 0 ..< ljTempArray.count

let dict:NSDictionary = ljTempArray\[m\] as! NSDictionary

let model = LJNewsModel()

model.imageUrl = dict.object(forKey: "imgsrc") as! String

model.contentStr = dict.object(forKey: "title") as! String

let count :Int = (dict.object(forKey: "replyCount") != nil) ? dict.object(forKey: "replyCount") as! Int : 0

model.replyCount = "\\(count)"

self.ljArray.add(model)

self.ljTablewView.reloadData()

func getDictionaryFromJSONString(jsonString:String) ->NSDictionary\{

let jsonData:Data = jsonString.data(using: .utf8)!

let dict = try? JSONSerialization.jsonObject(with: jsonData, options: .mutableContainers)

if dict != nil \{

return dict as! NSDictionary

return NSDictionary()

model

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

//方法二的model

override init() \{

super.init()

func setModel(\_ imageUrl: String ,\_ contentStr: String, \_ replyCount:Int) \{

self.imageUrl = imageUrl

self.contentStr = contentStr

self.replyCount = replyCount

2. 利用swift自有的函数进行解析-------推荐

//MARK:-- 数据获取和解析

extension NewsViewController\{

func requestNetData()\{

/\*

打印json数据

\*/

LJDownLoadNetImage.request("GET", url: "http://c.m.163.com/nc/article/list/T1348647909107/0-20.html") \{ (data, respond, error) in

//as? \[\[String :Any\]\] 转化为以字典为元素的数组

//as? \[String :Any\] 转化为字典

//1.方法一：解析数据 -- 推荐

let str = String(data:data!, encoding: String.Encoding.utf8)!

guard let allResulrDict = self.getDictionaryFromJSONString(jsonString:str) as? \[String : Any\] else \{return\}

guard let dataArray = allResulrDict\["T1348647909107"\] as? \[\[String :Any\]\] else \{return\}

//print(dataArray)

for dict in dataArray\{

self.ljArray.append(LJNewsModel(dict))

self.ljTablewView.reloadData()

func getDictionaryFromJSONString(jsonString:String) ->NSDictionary\{

let jsonData:Data = jsonString.data(using: .utf8)!

let dict = try? JSONSerialization.jsonObject(with: jsonData, options: .mutableContainers)

if dict != nil \{

return dict as! NSDictionary

return NSDictionary()

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) \{
