iOS swift JSON 到类对象

Question

当 JSON 有多个数组时，如何将 JSON 解析为一个类？我正在尝试将数据从 REST API 转换为我在 Swift 2.0 中的类，但我不知道如何正确地进行，有人可以提供帮助吗？

/* JSON from REST API
{
  "Name": "New name",
  "Email": "test@test.com",
  "FacebookId": "new facebook Id",
  "Address": "New Address",
  "Photo": "https://graph.facebook.com/novo facebook Id/picture?width=500&height=500",
  "CreditCards": [
    {
      "Id": 5,
      "LastNumber": "3123",
      "Brand": "visa"
    },
    {
      "Id": 6,
      "LastNumber": "3124",
      "Brand": "visa"
    }
  ]
}

swift 中的类表示？

    class Client {
  var fullName: String?
  var email: String?
  var facebookId: String?
  var photo: String?
  var creditCards: [CreditCard]?

  required init(json: JSON) {
    self.fullName = json["FullName"].string
    self.email = json["Email"].string
    self.facebookId = json["FacebookId"].string
    self.photo = json["Photo"].string
    self.creditCards = json["CreditCards"]["Id"]
  }

  required init() {}
}

class CreditCard {
  var Id: Int?
  var lastNumber: String?
  var brand: String?
}

您应该看看 NSJSONSerialization 类及其方法。它们完全满足您的需求:将 JSON 数据转换为数组、字典、字符串和数字。
