Question

我遇到了这个问题的障碍。我已尝试过这些URL1和URL2作为指导，但未成功。如何修复未填充UITableView的JSON？我在TableView中禁用我的阵列时遇到问题。

这是我的代码：

    class FilmsViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
        weak var tableView : UITableView!
        var FilmArray = [String]()

        let film_url = "https://www.testing.com/api/resources/films/1"
        func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return 1
        }
        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            // Getting the right element
            //let films = FilmArray[indexPath.row]


            // Instantiate a cell
            //let cell = UITableViewCell(style: .subtitle, reuseIdentifier: "moviecell")
            let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! FilmsAPITableViewCell
            //        cell.movieTitle.text = FilmArray[indexPath.row]
            // Adding the right informations
            cell.movieTitle.text = FilmArray[indexPath.row]
            // Returning the cell
            return cell
        }
       // @IBOutlet weak var FilmsView: UITableView!
    //    weak var tableView : UITableView!
    //    var FilmArray = [String]()
    //  
    //    let film_url = "https://www.distribber.com/api/resources/films/1"
    //    
        override func viewDidLoad() {
            super.viewDidLoad()

            let tableView = UITableView (frame:view.bounds)
            view.addSubview(tableView)
            self.tableView = tableView

            tableView.dataSource = self
            tableView.delegate = self


    //        func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    //            return 1
    //        }
    //            func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    //                // Getting the right element
    //               //let films = FilmArray[indexPath.row]
    //                
    //                
    //                // Instantiate a cell
    //                //let cell = UITableViewCell(style: .subtitle, reuseIdentifier: "moviecell")
    //                let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! FilmsAPITableViewCell
    //                //        cell.movieTitle.text = FilmArray[indexPath.row]
    //                // Adding the right informations
    //                cell.movieTitle.text = FilmArray[indexPath.row]
    //                // Returning the cell
    //                return cell
    //        }
               // }

            //}

将最后一个标题放入FilmArray来电tableview.reloadData()后。你必须在主队列上进行，否则你会得到意想不到的结果。
