Cocoa touch Xcode 4中的UINavigationController和UITabBarController

我已经从Xcode 3切换到了Xcode 4，我的整个工作流程模式都被破坏了。我之所以做出改变，是因为我认为iOS5只能在Xcode 4上开发

不管怎样，使用Interface Builder制作带有UITabBarController的UINavigationController对我来说过去很简单，现在我找不到正确的属性。感觉苹果已经忘记了列表中的某些属性

我将如何在xcode 4中完成与下面教程相同的内容

我得到一个不同的错误

如果要将FirstViewController从视图控制器更改为导航控制器，请编辑FirstViewController，使声明如下所示：

@interface FirstViewController : UIViewController {

我还看到视图及其控制器已经为您创建和连接

编辑

编辑的问题显示您尚未为FacetimeUsersViewController nib设置视图出口

请检查更新的错误。我在FaceUsersViewController上有一个tableView现在你有一个UITableViewController加载一个不是UITableView的视图。这是一个UITableView tho，这是我不明白的：我无法猜测发生了什么，除非我看到你是如何设置的。我有三个xib文件，一个是主窗口，上面有一个选项卡栏，一个选项卡是基本视图控制器，另一个是UInavigationcontroller。在UINavigationController中，视图控制器设置为FaceUsersViewController。FaceUsersViewController上有一个tableView，其委托和数据源设置为文件所有者，该文件所有者设置为FaceUsersViewController类。
