Swift Json将嵌套数组/字典解码为平面模型

import SwiftyJSON

// 定义数据模型类
class MyModel {
    var id: Int
    var name: String
    var items: [String]

    init(id: Int, name: String, items: [String]) {
        self.id = id
        self.name = name
        self.items = items
    }

    // 实现SwiftyJSON库的解码方法
    static func fromJson(json: JSON) -> MyModel? {
        guard let id = json["id"].int,
              let name = json["name"].string,
              let items = json["items"].arrayObject as? [String] else {
            return nil
        }

        return MyModel(id: id, name: name, items: items)
    }
}

// 解析Json数据
let jsonString = """
{
    "id": 1,
    "name": "Model 1",
    "items": ["Item 1", "Item 2", "Item 3"]
}
"""

let json = JSON(parseJSON: jsonString)
if let myModel = MyModel.fromJson(json: json) {
    print(myModel.id)      // 输出：1
    print(myModel.name)    // 输出："Model 1"
    print(myModel.items)   // 输出：["Item 1", "Item 2", "Item 3"]
}
