Question

这是我试图解析的JSON的结构。我希望能够循环访问问题。

{
  "status" : 200,
  "C&Q" : [
    {
      "category" : "Applicant Details",
      "questions" : [
        {
          "compulsory" : true,
          "options" : "Mr.; Mrs.; Miss",
          "input" : "radio",
          "question" : "Title"
        },
        {
          "compulsory" : true,
          "options" : "N\/A",
          "input" : "text",
          "question" : "Surname"
        }
      ]
    },
    {
      "category" : "Identification Documents",
      "questions" : [
        {
          "compulsory" : true,
          "options" : "Passport;Drivers License;Voter ID;NHIS",
          "input" : "radio",
          "question" : "ID TYPE"
        },
        {
          "compulsory" : true,
          "options" : "N\/A",
          "input" : "date",
          "question" : "Date of Issue (YYYY-MM-DD)"
        }
      ]
    }

此处的代码，但我只能通过索引访问。也许有人可以提供有关如何循环的示例代码，以便我可以访问问题数组。

let swiftyJsonVar = JSON(response.result.value!)

guard let questions = swiftyJsonVar["C&Q"].arrayValue[0]["questions"].arrayObject as? [[String:AnyObject]] else
{
    print("parsing failed")
    return
}

这就是我使用/计划使用适合上述解析的数组的方法。

let questionsStructs = questions.map(Questions.init)
self.formsData = questionsStructs

任何帮助将不胜感激。

var questions:[Question] = []
for (key,subJson):(String, JSON) in json["C&Q"] {
    for (key,j):(String, JSON) in subJson["questions"] {
        let question = Question(......)
        questions.append(question)
    }
}

使用SwifyJSON解析JSON
