Question

我正在尝试将检索到的JSON数据显示为UILabel。目前我已在调试器中成功显示数据，但我不确定如何设置相当于UILabel的数据。任何帮助，将不胜感激。

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var tableview: UITableView!

override func viewDidLoad()
{
    super.viewDidLoad()

    let url = URL(string: "http://cgi.soic.indiana.edu/~team10/index.php")

    let task = URLSession.shared.dataTask(with: url!) { (data, response, error) in
        if error != nil
        {
            print ("ERROR")
        }
        else
        {
            if let content = data
            {
                do
                {
                    //Array
                    let myJson = try JSONSerialization.jsonObject(with: content, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject
                        print(myJson)

                }
                catch
                {

                }
            }
        }
    }
    task.resume()

}

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


}

您可以尝试以下代码（URLSession dataTask是let body = try? JSONSerialization.jsonObject(with: data!, options: []) as AnyObject var jsonString = String() do { let jsonData = try JSONSerialization.data(withJSONObject: body, options: .prettyPrinted) jsonString = String(data: jsonData, encoding: .utf8)! print("jsonString: \(jsonString)") } catch let error as NSError { print(error) } DispatchQueue.main.async { self.sampleLabel.text = jsonString }中回调方法的参数）：

const time = timeToRedirect || TIME_TO_REDIRECT;
