ios - iOS：使用 Mantle 转换对象数组

Question

我正在使用 Mantle 序列化 json 字符串。

这是服务器返回的 json

"data": {
        "rows": {
        "0": {
            "id": 1,
            "rate": "13",
            "cycle": "22",
            "amount": "16",
            "name": "Nikita Kulas"
        },
        "1": {
            "id": 2,
            "rate": "14",
            "cycle": "25",
            "amount": "22",
            "name": "Nikita Kulas"
        },
        "2": {
            "id": 3,
            "rate": "7",
            "cycle": "8",
            "amount": "4",
            "name": "Nikita Kulas"
        },
        "4": {
            "id": 10,
            "rate": "18",
            "cycle": "24",
            "amount": "5",
            "name": "Nikita Kulas"
        }
    }
}

模型类是：

@interface QuantProduct : MTLModel <MTLJSONSerializing>

@property (nonatomic, copy, readonly) NSNumber *qpId;
@property (nonatomic, copy, readonly) NSString *requirement;
@property (nonatomic, copy, readonly) NSString *period;
@property (nonatomic, copy, readonly) NSString *rate;
@property (nonatomic, copy, readonly) NSString *name;

@end

@interface QuantProductList : MTLModel <MTLJSONSerializing>

@property (nonatomic, copy) NSArray<QuantProduct *> *quantProductList;

@end

@implementation QuantProduct


+ (NSDictionary *)JSONKeyPathsByPropertyKey {
    return @{
             @"qpId": @"id",
             @"name": @"name",
             @"requirement": @"amount",
             @"period": @"cycle",
             @"rate": @"rate"
             };
}

@end

@implementation QuantProductList

+ (NSDictionary *)JSONKeyPathsByPropertyKey {
    return @{
             @"quantProductList" : @"rows"
             };
}

+ (NSValueTransformer *)quantProductListJSONTransformer {
    return [MTLJSONAdapter arrayTransformerWithModelClass:[QuantProduct class]];
}


@end

我曾尝试使用 arrayTransformerWithModelClass 但它不是一个直接数组。

json中的索引键不是固定数字，那么我应该如何修改JSONTransformer方法才能直接序列化json呢？

谢谢
