iOS-json转OC模型对象

前言
准备工作
使用

在浏览器打开 - ViewController.html
将json粘贴进去

前言

当我们在将网络请求回来的数据进行OC模型的创建的时候，常常会有大量的重复的机械的拷贝

准备工作

生成一个Xcode的工程或者从随便一个工程拷贝一个Xocde的生成文件
拷贝到桌面 - 并且转为html的格式
使用打开方式为Xcode的打开方式拷贝以下代码

<html>
    <head>
        <meta charset="utf-8"/>
        <title>
        </title>
    </head>
    <body>
        <div style="text-align: center;">
            <textarea id="textarea" style="width: 600px;height: 250px;" placeholder="请输入json"></textarea>
        </div>
        <div style="text-align: center;">
            <button onclick="start()" style="width: 100px;height: 30px">转oc</button>
        </div>
        <div id="result" style="margin: 0 auto;width: 600px;font-size: 22px"></div>
    </body>
