ios - 使用 Swift 字典解析 JSON

Question

我很难用 Swift 解析 JSON。我编写了一个函数，它向 api 发出 get 请求，以 JSON 形式检索数据并将其转换为字典。之后，我尝试使用 tableViewController 根据从 JSON 收到的值设置每个标题和副标题。我正在尝试将标题设置为 homeTeam，将副标题设置为客队。我对 Swift 了解不多，所以希望得到一些帮助。

这是我存储在字典中的 JSON:

dictionary = ["scoreboard": {
    gameScore =     (
                {
            game =             {
                ID = 35119;
                awayTeam =                 {
                    Abbreviation = ATL;
                    City = Atlanta;
                    ID = 91;
                    Name = Hawks;
                };
                date = "2017-04-07";
                homeTeam =                 {
                    Abbreviation = CLE;
                    City = Cleveland;
                    ID = 86;
                    Name = Cavaliers;
                };
                location = "Quicken Loans Arena";
                time = "7:30PM";
            };
            isCompleted = false;
            isInProgress = false;
            isUnplayed = true;
            quarterSummary = "<null>";
        },
                {

            isUnplayed = true;
            quarterSummary = "<null>";
        }
    );
    lastUpdatedOn = "<null>";
}]

以下是我目前在 Swift 中设置标题和副标题的内容:

 override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "NBAScore", for: indexPath)

        // Configure the cell...                
        if let scoreBoard = d.dictionary["scoreboard"] as? [String:AnyObject]
        {
            if let gameScore = scoreBoard["gameScore"] as? [String:AnyObject]
                {
                    if let game = gameScore["game"] as? [String:AnyObject]
                        {
                            if let awayTeam = game["awayTeam"] as? String
                                {
                                    cell.textLabel?.text = awayTeam                             }
                        }
                }
        }
        return cell
    }

最好是为您需要的属性创建一个结构添加变量，然后从该结构创建一个数组，使用 for 循环解析您的 json 数组，并将它们附加到您创建的新数组中，然后您可以访问这些属性在 cellForRow 函数中使用点表示法
