Question

我设置了带有操作表的表格视图。但是每当介绍操作表时我都会遇到问题。

这是代码和图像的一部分。

class MoviesTableViewController: UIViewController {

    @IBOutlet weak var moviesTableView: UITableView!
    private let actionSheet = UIAlertController(title: "정렬방식 선택", message: "영화를 어떤 순서로 정렬할까요?", preferredStyle: .actionSheet)
    private var movies: Movies?
    private var api: BoxOfficeAPI?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        
        moviesTableView.estimatedRowHeight = moviesTableView.rowHeight
        moviesTableView.rowHeight = UITableView.automaticDimension
        
        NotificationCenter.default.addObserver(self, selector: #selector(setData(_:)), name: .MoviesNotification, object: nil)
        moviesTableView.delegate = self
        moviesTableView.dataSource = self
        configureRefreshControl()
        
        api = BoxOfficeAPI(with: "https://connect-boxoffice.run.goorm.io/movies?order_type=0", and: .Movies)
        api?.request()
        
        actionSheet.addAction(UIAlertAction(title: "예매율", style: .default, handler: { _ in

        }))
        actionSheet.addAction(UIAlertAction(title: "큐레이션", style: .default, handler: { _ in

        }))
        actionSheet.addAction(UIAlertAction(title: "개봉일", style: .default, handler: { _ in

        }))
        actionSheet.addAction(UIAlertAction(title: "취소", style: .cancel, handler: { _ in
            
        }))
    }

    func configureRefreshControl() {
        moviesTableView.refreshControl = UIRefreshControl()
        moviesTableView.refreshControl?.addTarget(self, action: #selector(handleRefreshControl), for: .valueChanged)
    }
    
    @objc func handleRefreshControl() {
        self.moviesTableView.reloadData()

        DispatchQueue.main.async {
            self.moviesTableView.refreshControl?.endRefreshing()
        }
    }
    
    @IBAction func setOrder(_ sender: UIBarButtonItem) {
        present(actionSheet, animated: true, completion: nil)
    }
}

我能知道为什么会发生吗？

得到“ [LayoutConstraints]无法同时满足约束。”在ActionSheet中
