arrays - 自定义TableView错误

Question

我正在尝试创建一个自定义表格 View ，但偶然发现了每个代码。截至目前，我在下面有这个。这很困惑而且可能是错误的，但有人可以帮忙吗？

此外，我不断收到错误代码

unexpectedly found nil while unwrapping optional value

import UIKit

class tableOutlineViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

    @IBOutlet weak var tableView: UITableView!


    var names = ["Max", "Bill", "Reagan", "Mikayla", "Jessie", "Sierra", "Jeff", "Erik", "Landon"]
    var numbers = ["35", "33", "29", "27", "25", "23", "19", "15", "11"]
    var photo = [UIImage(named: "Person1"), UIImage(named: "Person2"), UIImage(named: "Groceries"), UIImage(named: "Person3"), UIImage(named: "Person4"), UIImage(named: "Person5"), UIImage(named: "Person6"), UIImage(named: "Person7")]


    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

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

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

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

        cell.images.image = photo[indexPath.row]
        cell.name.text = names[indexPath.row]
        cell.number.text = numbers[indexPath.row]


        return cell
    }

}

错误位于以下行，因为它无法强制展开 CustomCell:

let cell = self.tableView.dequeueReusableCell(withIdentifier: "CustomCell") as! CustomCell

由于您可能在自定义单元格中使用 Nib，因此您应该首先在 viewDidLoad 中注册它。

let nib = UINib(nibName: YOUR_CUSTOM_CELL_NIB_NAME, bundle: nil)
tableView.register(nib, forCellReuseIdentifier: "CustomCell")
