数据不会显示在带有自定义单元格

Question

我有一个TabViewController，它指向两个TableViewControllers，我已经制作了第一个自定义单元格。但是，当我运行应用程序时，数据没有加载到单元格中，并且所有内容都是一个没有数据和两个选项卡的空白表格视图，显然当我侧身翻转应用程序时，应用程序崩溃并出现错误：** *由于未捕获的异常终止应用程序＆＃39; NSInternalInconsistencyException＆＃39;，原因：＆＃39;无法使用标识符LotteryTableViewCell对单元格进行出列 - 必须为标识符注册一个nib或类或在故事板中连接原型单元格＆＃ 39 ;.我已经尝试使用标识符注册应用程序，但是当我这样做时，我得到一个错误，它无法将表视图转换为我的LotteryTableViewCell。并不是数据是空的，因为我正在打印数据并且它打印出来非常好。此外，我还在storyboard属性中设置了单元格标识符。谢谢，感谢任何帮助。

自定义单元格：

import UIKit

class LotteryTableViewCell: UITableViewCell {
// MARK: Properties

@IBOutlet weak var position: UILabel!
@IBOutlet weak var teamLogo: UIImageView!
@IBOutlet weak var teamName: UILabel!
@IBOutlet weak var player: UILabel!
@IBOutlet weak var record: UILabel!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
}
