表格視圖未顯示單元格快速

Question

我創建了一個Restaurant類，並進行了所有連接以顯示單元格，但是當我點擊run時，它並沒有顯示我創建的所有網點。

這是我的代碼：

import UIKit

class RestaurantTableViewController: UITableViewController {

    var restaurants:[Resturant] = [
        Resturant(name: "Hardees", type: "Burger", location: "Many", image: "Hardees.jpg", isVisited: false), Resturant(name: "Shake Shack", type: "Burger", location: "Gulf Mall", image: "shakeshack.jpg", isVisited: false), Resturant(name: "Burgery", type: "Burger", location: "Gulf Mall", image: "shakeshack.jpg", isVisited: false), Resturant(name: "Dairy Queen", type: "Burger", location: "Gulf Mall", image: "shakeshack.jpg", isVisited: false), Resturant(name: "Elevation Burger", type: "Burger", location: "Gulf Mall", image: "shakeshack.jpg", isVisited: false), Resturant(name: "Fat Burger", type: "Burger", location: "Gulf Mall", image: "shakeshack.jpg", isVisited: false)
    ]


    override func viewDidLoad() {
        super.viewDidLoad()

        // Uncomment the following line to preserve selection between presentations
        // self.clearsSelectionOnViewWillAppear = false

        // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
        // self.navigationItem.rightBarButtonItem = self.editButtonItem()
    }

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

    // MARK: - Table view data source

    override func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return restaurants.count
    }


    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cellIdentifier = "Cell"
        let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! CustomTableViewCell

        // Configure the cell...
        cell.nameLabel.text = restaurants[indexPath.row].name
        cell.thumbnailImageView.image = UIImage(named: restaurants[indexPath.row].image)
        cell.locationLabel.text = restaurants[indexPath.row].location
        cell.typeLabel.text = restaurants[indexPath.row].type

        cell.accessoryType = restaurants[indexPath.row].isVisited ? .checkmark : .none

        return cell
    }




    override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

        if editingStyle == .delete {
            // Delete the row from the data source
            restaurants.remove(at: indexPath.row)
        }

        tableView.deleteRows(at: [indexPath], with: .fade)
    }

    override func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {

        // Social Sharing Button
        let shareAction = UITableViewRowAction(style: UITableViewRowActionStyle.default, title: "Share", handler: { (action, indexPath) -> Void in

            let defaultText = "Just checking in at " + self.restaurants[indexPath.row].name

            if let imageToShare = UIImage(named: self.restaurants[indexPath.row].image) {
                let activityController = UIActivityViewController(activityItems: [defaultText, imageToShare], applicationActivities: nil)
                self.present(activityController, animated: true, completion: nil)
            }
        })

        // Delete button
        let deleteAction = UITableViewRowAction(style: UITableViewRowActionStyle.default, title: "Delete",handler: { (action, indexPath) -> Void in

            // Delete the row from the data source
            self.restaurants.remove(at: indexPath.row)

            self.tableView.deleteRows(at: [indexPath], with: .fade)
        })

        shareAction.backgroundColor = UIColor(red: 48.0/255.0, green: 173.0/255.0, blue: 99.0/255.0, alpha: 1.0)
        deleteAction.backgroundColor = UIColor(red: 202.0/255.0, green: 202.0/255.0, blue: 203.0/255.0, alpha: 1.0)

        return [deleteAction, shareAction]
    }

    // MARK: -

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "showRestaurantDetail" {
            if let indexPath = tableView.indexPathForSelectedRow {
                let destinationController = segue.destination as! ResturantDetailViewController
                destinationController.resturant = restaurants[indexPath.row]
            }
        }
    }
}

Answer 1

在情節提要中，您將“漢堡餐廳”表控制器鏈接到：

ResturantTableTableViewController

就像文件“ ResturantTableTableViewViewController.swift”一樣，但是在此文件中，您將其聲明為：

class RestaurantTableViewController: UITableViewController {

故事板將忽略文件名，但使用您在文件內部聲明的名稱。

更改文件名並將情節提要鏈接到同一類。 或者，您可以將“ ResturantTableTableViewController.swift”文件中的類名稱更改為與文件名相同的名稱（“ ResturantTableTableTableViewController”）。

Answer 2

嘿，我想通了您的問題，在Interface Builder你的自定義類設置為RestaurantTableTableView當您需要將其設置為你實際文件名RestaurantTableViewController 。
