Question

每个人，在查找有关如何为我的Movie DB应用程序实现搜索过滤器的文档时都遇到困难，因为到目前为止我的代码都无法附加，因此我设法将数据显示在表格视图中

标题和图像我现在需要做的是能够使用搜索栏过滤电影，然后在单击一行时转到新的View控制器，该控制器显示有关电影的扩展信息，然后单击“书签”按钮将其保存到核心数据中，然后出现在书签屏幕上，以供用户稍后查看。

预先感谢

我的代码在这里：

    import UIKit
    import AFNetworking
    class ViewController: UIViewController, UITableViewDataSource, 
    UITableViewDelegate, UISearchBarDelegate {
    var movies: [NSDictionary]?
    @IBOutlet weak var txtSearch: UITextField!
    @IBOutlet weak var tableView: UITableView!
    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.dataSource = self
        tableView.delegate = self
        // Do any additional setup after loading the view, typically from a nib.
     fetchMovies()
     searchBar()
    }
    func searchBar(){
        let searchBar = UISearchBar(frame: CGRect(x: 0, y: 0, width: 
        self.view.frame.width, height: 50))
        searchBar.delegate = self
        searchBar.showsScopeBar = true
        searchBar.tintColor = UIColor.lightGray
        searchBar.scopeButtonTitles = ["Now Playing"]
        self.tableView.tableHeaderView = searchBar
        }
       func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
      {
        if searchText == ""{
            fetchMovies()
        }else{
            if searchBar.selectedScopeButtonIndex == 0 {
                movies = movies?.filter({ (movies) -> Bool in
                    return movies.title.lowercased()
                })
            }
        }
    }
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
        return movies?.count ?? 0
    }

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

        let movie = movies![indexPath.row]
        let title = movie["title"] as! String
        let posterPath = movie["poster_path"] as! String
        let baseUrl = "https://image.tmdb.org/t/p/w300/"
        let imageUrl = NSURL(string: baseUrl + posterPath)
        cell.lblTitle.text = title
        cell.imgMovie.setImageWith(imageUrl! as URL)
        print("row \(indexPath.row)")
        return cell

    }
    func fetchMovies(){
        let apiKey = "2c0a8efe934c162f5535ff33303e70bd"
        let url = NSURL(string: "https://api.themoviedb.org/3/movie/now_playing?api_key=\(apiKey)")
        let request = URLRequest(url: url! as URL, cachePolicy: NSURLRequest.CachePolicy.reloadIgnoringCacheData, timeoutInterval: 10)
        let session = URLSession(
            configuration: URLSessionConfiguration.default, delegate: nil, delegateQueue: OperationQueue.main
        )
        let task: URLSessionDataTask =  session.dataTask(with: request, completionHandler:{(dataOrNil, repsonse, error) in
            if let data = dataOrNil {
                if let responseDictionary = try! JSONSerialization.jsonObject(with: data, options: []) as? NSDictionary{print("response: \(responseDictionary)")
                    self.movies = responseDictionary["results"] as? [NSDictionary]
                    self.tableView.reloadData()

                }
            }

        })
            task.resume()
    }

    @IBAction func btnBookmark(_ sender: UIButton) {
    }
    }
