iOS Swift：如何将响应从服务器更改为特定格式？

Question

我将数据从服务器存储到NSArray，在这里我想将当前格式更改为新格式。 但我不知道如何将当前格式更改为new。请帮助我制作格式。 在这里，我共享了以下旧格式和新格式。

这是从服务器收到的旧格式。

{
{
“class” = “12”,
“section” = “A”,
“name” = “aathi”,
“mark” = “850”,
“school” = “ab matriculation school”,
“place” = “Chennai”
},
{
“class” = “12”,
“section” = “B”,
“name” = “ram”,
“mark” = “904”,
“school” = “ab matriculation school”,
“place” = “delhi”
},
{
“class” = “10”,
“section” = “C”,
“name” = “ashok”,
“mark” = “389”,
“school” = “psg hr sec school”,
“place” = “coimbatore”
},
{
“class” = “8”,
“section” = “B”,
“name” = “sundar”,
“mark” = “267”,
“school” = “govt hr sec school”,
“place” = “Madurai”
}

}

我想更改如下的新格式。

{
{
“class” = “12”,
“section” = “A”,
“school” = “ab matriculation school”,
noncommondetails:{
        {
        “name” = “aathi”,
        “mark” = “850”,
        “place” = “Chennai”
        },
        {
        “name” = “ram”,
        “mark” = “904”,
        “place” = “delhi”
        }
    }
},
{
“class” = “10”,
“section” = “C”,
“school” = “psg hr sec school”,
noncommondetails:{
        {
        “name” = “ashok”,
        “mark” = “389”,
        “place” = “coimbatore”
        }
    },
},
{
“class” = “8”,
“section” = “B”,
“school” = “govt hr sec school”,
noncommondetails:{
        {
        “name” = “sundar”,
        “mark” = “267”,
        “place” = “Madurai”
        },
    }
}

}

Answer 1

您必须尝试https://github.com/Hearst-DD/ObjectMapper进行json对象映射。

Answer 2

最好的设计是为服务器响应创建模型，然后将这些模型对象保存在数组中。 这样，您可以更改所需的内容。

旧格式的模型：

struct Item {
    var aClass:String?
    var section:String?
    var name:String?
    var mark:String?
    var school:String?
    var place:String?
}

现在为新的更新服务器响应建模：

struct Item {
    var aClass:String?
    var section:String?
    var school:String?
    var nonCommonDetails : [NonCommenItem]?
}

struct NonCommenItem {
    var name:String?
    var mark:String?
    var place:String?
}

然后您可以像这样使用它：

let nonCommenItem1 = NonCommenItem(name: "aathi", mark: "850", place: "Chennai")
let nonCommenItem2 = NonCommenItem(name: "ram", mark: "904", place: "delhi")

let item1 = Item(aClass: "12", section: "B", school: "ab matriculation school", nonCommonDetails: [nonCommenItem1,nonCommenItem2])

我希望这能解决您的问题。 如有任何疑问，请询问。 祝好运 ：）
