- 急于分享，不说废话了，请看↓。
Json数据如下
- 文字描述如下Json数据的格式:
- 字典A内嵌数组B(infor对应的value)
- 数组B内嵌字典C
- 字典C又内嵌数组D1和D2。 (D1是workerItems对应的value；D2是imgItems对应的value)
- 数组D1又内嵌字典E1，E2。数组D2又内嵌字典F1,F2

表视图格式如下

解析很简单:
- 正确写法:无论AS_ZBPostOrderDetailModel模型中嵌套了多少(模型)数组,一定只要用一个mj_setupObjectClassInArray:方法来包装两个模型数组。
NSArray *temArr = [info objectForKey:@"infor"];
// id用postOrderID替代，模型中直接声明postOrderID属性,不用再声明id了。id为系统字段，所以必须替换成常规字段。
[AS_ZBPostOrderDetailModel mj_setupReplacedKeyFromPropertyName:^NSDictionary *{
return @{@"OrderDetailID" : @"id"};
}];
************正确步骤1:************
// AS_ZBPostOrderDetailModel模型中嵌套了两个模型数组,一定要按照如下的格式写，不要分开。
// 告诉MJExtension这个框架AS_ZBPostOrderDetailModel的workerItems数组属性中装的是AS_ZBPostOrderWorkerItemModel 模型,imgItems数组属性中装的是AS_ZBPostOrderImgItemModel 模型
[AS_ZBPostOrderDetailModel mj_setupObjectClassInArray:^NSDictionary *{
return @{@"workerItems" : @"AS_ZBPostOrderWorkerItemModel",
@"imgItems" : @"AS_ZBPostOrderImgItemModel"
};
}];
************正确步骤2:************
self.Marray = [AS_ZBPostOrderDetailModel mj_objectArrayWithKeyValuesArray:temArr];
- 错误写法(楼主经历过):执行了两次mj_setupObjectClassInArray:方法。B会覆盖掉A.所以A就相当于没有转成AS_ZBPostOrderWorkerItemModel模型
NSArray *temArr = [info objectForKey:@"infor"];
// id用postOrderID替代，直接声明postOrderID属性即可
[AS_ZBPostOrderDetailModel mj_setupReplacedKeyFromPropertyName:^NSDictionary *{
return @{@"OrderDetailID" : @"id"};
}];
// A
[AS_ZBPostOrderDetailModel mj_setupObjectClassInArray:^NSDictionary *{
return @{@"workerItems" : @"AS_ZBPostOrderWorkerItemModel",
};
}];
// B
[AS_ZBPostOrderDetailModel mj_setupObjectClassInArray:^NSDictionary *{
return @{@"imgItems" : @"AS_ZBPostOrderImgItemModel"
};
}];
self.Marray = [AS_ZBPostOrderDetailModel mj_objectArrayWithKeyValuesArray:temArr];
