将json数据分配给标签

Question

我是快速编程的初学者，我想将数据分配给标签

所以我在下面有此代码

@IBOutlet weak var Infected: WKInterfaceLabel!
    @IBOutlet weak var Cured: WKInterfaceLabel!
    @IBOutlet weak var Deaths: WKInterfaceLabel!

    @IBOutlet weak var OmanInfected: WKInterfaceLabel!
    @IBOutlet weak var OmanCured: WKInterfaceLabel!
    @IBOutlet weak var OmanDeaths: WKInterfaceLabel!


    func check()
    {


        struct CoronaData:Codable{
            var countrydata:String
           var total_active_cases:Int
           var total_cases:Int
           var total_danger_rank:Int
           var total_deaths:Int
           var total_new_cases_today:Int
           var total_new_deaths_today:Int
           var total_recovered:Int
           var total_serious_cases:Int
           var total_unresolved:Int
        }

        if let url = URL(string: "https://api.thevirustracker.com/free-api?countryTotal=OM") {
           URLSession.shared.dataTask(with: url) { data, response, error in
              if let data = data {
                  do {
                     let res = try JSONDecoder().decode(CoronaData.self, from: data)
                    print(res.countrydata)
                  } catch let error {
                     print(error)
                  }
               }
           }.resume()
        }

        AF.request("https://api.thevirustracker.com/free-api?countryTotal=OM").response {respond in debugPrint(respond)}

    }

并且我在控制台菜单中获得此数据

typeMismatch(Swift.String, Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "countrydata", intValue: nil)], debugDescription: "Expected to decode String but found an array instead.", underlyingError: nil))

现在如何将这些值分配给此处的标签（数字标签）

我知道这是一个愚蠢的问题，但请原谅我我只想完成程序并学习一些新事物

Answer 1

countrydata表示为数组，但是模型中的相应属性为String类型。

Answer 2

您可以下载此免费程序来构建结构

请参见此example以使用struct

         if let url = URL(string: "https://api.thevirustracker.com/free-api?countryTotal=OM") {
           URLSession.shared.dataTask(with: url) { data, response, error in
              if let data = data {
                  do {
                     let decoder = JSONDecoder()
                     let profile = try decoder.decode(ProfileResponse.self, from: data)
                     print(profile)
                  } catch let error {
                     print(error)
                  }
               }
           }.resume()
        }

您可以使用setText（:)或setAttributedText（ :)方法以编程方式更改文本。
