@interface tableview:UIViewController ....
而不是UIViewController尝试使用UIView
答案 1 :(得分:0)
我认为你错过了UITableViewDelegate
。
答案 2 :(得分:-1)
您的代码现已完成。你的“tableView”不是真正的UITableView,它是UIViewController!
你应该在你的h文件和xib文件中有UITableView实例,然后将它们相互链接,并将UITableViewDelegate属性设置为你的UIViewcontroller类。
请查看基本的UITableView(或UITableViewController)样本......
