ios - JSONModel:模型集合到JSON并手动添加集合

Question

假设我有这个模型。

@protocol ProductModel
@end

@interface ProductModel : JSONModel
@property (assign, nonatomic) int id;
@property (strong, nonatomic) NSString* name;
@property (assign, nonatomic) float price;
@end

@implementation ProductModel
@end

@interface OrderModel : JSONModel
@property (assign, nonatomic) int order_id;
@property (assign, nonatomic) float total_price;
@property (strong, nonatomic) NSArray<ProductModel>* products;
@end

@implementation OrderModel
@end

问题:

1. 如何在此数组中添加产品？

2. 然后如何生成以下 JSON。

   “产品”:[ { “编号”:“123”， “名称”:“产品#1”， “价格”:12.95 }, { “编号”:“137”， “名称”:“产品#2”， “价格”:82.95 } ]

或整个对象。

{
  "order_id": 104,
  "total_price": 103.45,
  "products" : [
    {
      "id": "123",
      "name": "Product #1",
      "price": 12.95
    },
    {
      "id": "137",
      "name": "Product #2",
      "price": 82.95
    }
  ]
}

我认为BWJSONMatcher可以以非常巧妙的方式帮助您:

ProductModel *productModel1 = [[ProductModel alloc] init];
productModel1.id = 123;
productModel1.name = @"Product #1";
productModel1.price = 12.95;

ProductModel *productModel2 = [[ProductModel alloc] init];
productModel2.id = 137;
productModel2.name = @"Product #2";
productModel2.price = 82.95;

OrderModel *orderModel = [[OrderModel alloc] init];
orderModel.order_id = 104;
orderModel.total_price = 103.45;
orderModel.products = @[productModel1, productModel2];

NSString *producedJSON = [orderModel toJSONString];
