ios - 无法返回正确的 JSON 值

Question

我一直试图在处理 JSON 数据时返回我收到的数据中的特定值，但我似乎无法获得特定值。我只能得到所有的信息。这是更详细的问题:

代码:

class ViewController: UIViewController, NSURLConnectionDelegate {

lazy var data = NSMutableData()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    startConnection()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func startConnection(){
    let urlPath: String = "https://na.api.pvp.net/api/lol/na/v1.4/summoner/by-name/soon2challenger?api_key=(removed my private API key for obvious reasons)"
    var url: NSURL = NSURL(string: urlPath)!
    var request: NSURLRequest = NSURLRequest(URL: url)
    var connection: NSURLConnection = NSURLConnection(request: request, delegate: self, startImmediately: false)!
    connection.start()
}

func connection(connection: NSURLConnection!, didReceiveData data: NSData!){
    self.data.appendData(data)
}

func buttonAction(sender: UIButton!){
    startConnection()
}

func connectionDidFinishLoading(connection: NSURLConnection!) {
    var err: NSError
    // throwing an error on the line below (can't figure out where the error message is)
    var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as! NSDictionary
    println(jsonResult)
  }
}

代码运行良好。这是我得到的结果。

{
soon2challenger =     {
    id = 43993167;
    name = soon2challenger;
    profileIconId = 844;
    revisionDate = 1435549418000;
    summonerLevel = 30;
   };
}

问题是，当我想从列表中返回某个值时，如在 id 中，我似乎无法那样做。我尝试执行 println(jsonResult["id"]) 但这只是结果为零。

如何从列表中返回某个值？前任。 id, name, profileIconId

尝试像这样使用 objectForKey:

let inside = jsonResult.objectForKey("soon2challenger")

现在您已经提取了 soon2challenger 对象。然后就可以轻松获取值了:

print(include.objectForKey("id"))
