我正在尝试创建一个视频播放器，它在 UITableView 中显示视频的缩略图、标题和描述。当用户点击 raw 时，它将打开一个带有 WebView 的新视图，视频将在其中播放。
目前，我仍在尝试设置自定义单元格。我AppDelegate.swift在该行的文件上遇到错误class AppDelegate: UIResponder, UIApplicationDelegate {，错误是：Thread 1: signal SIGABRT. 错误日志在这篇文章的末尾。
在其中，我添加了一个带有一个原型单元格的 TableView（我使用andMain.storyboard连接到 ViewController ），其中我添加了一个 ImageView 和两个标签。我还创建了一个名为. 我将自定义类设置为 ViewController，将单元格的标识符设置为，将样式设置为“自定义”，并将其类设置为.delegatedataSourceCustomTableViewCell.swiftView ControllercustomCellCustomTableViewCell
在ViewController.swift我创建了一个包含视频信息的数组并设置了表函数。
我还尝试了其他方法来使用我在 Stack 上找到的解决方案编写代码，但我也遇到了同样的错误，或者在最大情况下我得到了一个包含 3 个空单元格的表格。代码在下面。有人能告诉我如何让这个自定义单元格工作吗？
提前致谢！
