上篇文章说了自己在公司代码遇到的问题,可维护性很低,做了很多无用功才熟悉代码。点击打开链接http://blog.csdn.net/a158337/article/details/50550941
今天我把原来的代码的核心部分都改了,和昨天实现的效果没有变,但是以后的可维护性一定更好了。
模型文件
#import <Foundation/Foundation.h>
/**
* 速递红包模型
/**
*
user_id
page 页数(每页10个)
返回示例:
请求成功且有可用优惠券时:
{"code":200,"message":"success","content":
{"coupon_info":[
{
"coupon_id":"323",
"is_used":"2",
"source":"商城发放",
"give_time":"2015.10.12",
"coupon_price":"1.5",
"available_time":"23小时后可用"
},
{"coupon_id":"25003",
"is_used":"0",
"source":"系统发放",
"give_time":"2015.08.20 17:46",
"expire_time":"2015.08.29 17:46",
"coupon_price":"1.5"
}
]
}
}
请求成功但没有可用的优惠券时:
{"code":200,"message":"success","content":{"coupon_info":null}}
备注: is_used 0 为未使用, 2为不可用

用模型的话可以添加些注释,而且模型对象通过点语法访问属性的时候可以看到自己注释的内容,减少了代码的来回粘贴、
