我想你错过了UITableViewDelegate。

@interface 表视图：UIViewController....

而不是 UIViewController 尝试使用 UIView

您的代码现在不完整。您的“tableView”不是真正的 UITableView，它是 UIViewController！

您应该在 h 文件和 xib 文件中有 UITableView 实例，然后将它们相互链接，并将 UITableViewDelegate 属性设置为您的 UIViewcontroller 类。

请查看基本的 UITableView（或 UITableViewController）示例...
