JsonToModelFile
我们在做项目的时候经常会遇到要通过网络请求得到的json数据来创建Model类文件，有时得到的json文件可能会比较复杂手动的创建Model总感觉费时又费力，例如下面的json数据:
{
"salesOrder" : {
"assistant1" : "xxx",
"assistantId" : "000001",
"deliveryType" : "Y",
"deliveryTypeName" : "送货上门",
"needInstall" : "Y",
"orderDate" : "1525507017000",
"orgId" : "A",
"orgName" : "xxx有限公司",
"priceSum" : "3.000000",
"refundType" : "1",
"requireArriveDate" : "152559xxx",
"salesOrderParts" : [
{
"billPrice" : "3.00",
"goods" : {
"enableSn" : "",
"giftFlag" : "",
"goodsTypeName" : "",
"id" : "",
"partName" : "豪华电饭煲CFXB50YB8-70//4",
"pnModel" : "5L",
"serialRuleId" : ""
},
"partRecId" : "01.01.01.400050",
"priceRate" : "0.000000",
"qtyPlan" : "1",
"unitId" : "tai",
"unitName" : "台",
"unitPrice" : "3"
}
],
"subscribeDispatch" : "N",
"warehouseId" : "1013",
"warehouseName" : "xxx库"
},
"salesRefund" : {
"assistant1" : "sss",
"assistantId" : "000001",
"buyerId" : "QB027",
"buyerName" : "北xxxx）",
"orderDate" : "1525507017000",
"orgId" : "A",
"orgName" : "xxx有限公司",
"priceSum" : "3.000000",
"refundType" : "1",
"requireArriveDate" : "152559xxxx",
"salesOrderParts" : [
{
"billPrice" : "3.00",
"goods" : {
"enableSn" : "",
"goodsTypeId" : "",
"goodsTypeName" : "",
"id" : "",
"partName" : "xxxCFXB40YB8-70//4",
"pnModel" : "4L",
"serialRuleId" : "",
"unitId" : "",
"unitName" : ""
},
"partRecId" : "01.01.01.400043",
"priceRate" : "0.000000",
"qtyPlan" : "1",
"unitId" : "tai",
"unitName" : "台",
"unitPrice" : "3"
}
],
"warehouseId" : "1011",
"warehouseName" : "xxx"
}
}
复制代码一看就知道我去手动的写Model类好累啊（这一个json文件需要写5个类文件）如果你像我这样通过KVC的方式给对象赋值那么你还得手动的去重写KVC的一 些方法，所以就在考虑可不可以通过代码自动生成Model文件同时生成需要重写的KVC方法呢？这样就可以节省很多时间在做低级没有技术含量的事情，把更多 的时间放在有用的地方，于是就有了现在的这个工具"JsonToModelFile"。
JsonToModelFile它需要你给这个josn命名一个“根类”，例如上面的例子我可以命名为“Test”。josn里面会有嵌套的字典和数组他们生成的类的名称 就是它门key的名称，例如：
{
"salesOrder" : {
"assistant1" : "xxx",
"assistantId" : "000001",
"deliveryType" : "Y",
"deliveryTypeName" : "送货上门",
"needInstall" : "Y",
"orderDate" : "1525507017000",
"orgId" : "A",
"orgName" : "xxx有限公司",
"priceSum" : "3.000000",
"refundType" : "1",
"requireArriveDate" : "152559xxx",
"salesOrderParts" : [
{
"billPrice" : "3.00",
"goods" : {
"enableSn" : "",
"giftFlag" : "",
"goodsTypeName" : "",
"id" : "",
"partName" : "豪华电饭煲CFXB50YB8-70//4",
"pnModel" : "5L",
"serialRuleId" : ""
},
"partRecId" : "01.01.01.400050",
"priceRate" : "0.000000",
"qtyPlan" : "1",
"unitId" : "tai",
"unitName" : "台",
"unitPrice" : "3"
}
],
"subscribeDispatch" : "N",
"warehouseId" : "1013",
"warehouseName" : "xxx库"
},
"salesRefund" : {
"assistant1" : "sss",
"assistantId" : "000001",
"buyerId" : "QB027",
"buyerName" : "北xxxx）",
"orderDate" : "1525507017000",
"orgId" : "A",
"orgName" : "xxx有限公司",
"priceSum" : "3.000000",
"refundType" : "1",
"requireArriveDate" : "152559xxxx",
"salesOrderParts" : [
{
"billPrice" : "3.00",
"goods" : {
"enableSn" : "",
"goodsTypeId" : "",
"goodsTypeName" : "",
"id" : "",
"partName" : "xxxCFXB40YB8-70//4",
"pnModel" : "4L",
"serialRuleId" : "",
"unitId" : "",
"unitName" : ""
},
"partRecId" : "01.01.01.400043",
"priceRate" : "0.000000",
"qtyPlan" : "1",
"unitId" : "tai",
"unitName" : "台",
"unitPrice" : "3"
}
],
"warehouseId" : "1011",
"warehouseName" : "xxx"
}
}
"salesOrderParts" : [
{
"billPrice" : "3.00",
"goods" : {
"enableSn" : "",
"goodsTypeId" : "",
"goodsTypeName" : "",
"id" : "",
"partName" : "xxxCFXB40YB8-70//4",
"pnModel" : "4L",
"serialRuleId" : "",
"unitId" : "",
"unitName" : ""
},
"partRecId" : "01.01.01.400043",
"priceRate" : "0.000000",
"qtyPlan" : "1",
"unitId" : "tai",
"unitName" : "台",
"unitPrice" : "3"
}
]
复制代码会生成一个SalesOrderParts名称的Model类，例如：
"goods" : {
"enableSn" : "",
"giftFlag" : "",
"goodsTypeName" : "",
"id" : "",
"partName" : "豪华电饭煲CFXB50YB8-70//4",
"pnModel" : "5L",
"serialRuleId" : ""
}
复制代码会生成一个Goods名称的Model类。还有你会发现上例子里的json有两个同名的goods他们将会把里面的字段并归到一个Goods类。实际运行结果请看ViewController使用实例。
#import "ViewController.h"
#import "YYOCLanguage.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];

}
