UITableView出现问题:继续获取此运行时错误无法识别的选择器 [英] UITableView woes: Keep on getting this runtime error unrecognised selector

问题描述

我有这个错误使我无法前进.我基本上有一个应用程序，其中包含指向单个UIViewControllers的UITabViewController.因此，其中一个标签是我要实现一个基本的TableViewController.

I have this error that is keeping me from moving forward. I basically have an application which contains a UITabViewController which points to individual UIViewControllers. So one of the tabs, I want to implement a basic TableViewController.

现在，无论我做什么，无论是剪切并粘贴实现UITableView的示例UIViewController代码，还是什至只是Xcode中的默认UITableViewController模板，我都在下面得到相同的错误:

Now, no matter what i do, whether its cut and paste sample UIViewController code that implements a UITableView, or whatever, or even just the default UITableViewController template from Xcode, i get the same error below:

在IB中，我所做的只是将UITableView拖到视图上，并将其委托设置为指向文件所有者.

In IB, all I have done is drag onto the view a UITableView and set its delegates to point to the file owner.

不确定我还能从这里做什么

Not sure what else i can do from here

推荐答案

确保IB中的File Owner对象设置为您要实现的UITableViewController子类的实例，并且它具有tableView链接到您的表格视图的插座.

Make sure that the File's Owner object in IB is set to be an instance of the UITableViewController subclass that you're implementing, and that it has a tableView outlet that's linked to your table view.
