RootViewController上的NSInternalInconsistencyExceptionException [英] NSInternalInconsistencyException on RootViewController

问题描述

我正在尝试创建一个导航类型的应用程序，但我想自定义初始视图，以使tableview不会占据整个框架，而是嵌入到一个子视图中，这样我就可以添加一些标签和首次启动该应用程序时的图片.

I'm trying to create a navigation-stype app, but I want to customize the initial view so that the tableview doesn't occupy the entire frame, but rather is embedded within a sub-view so I can some labels and an image when the app is first launched.

我在RootViewController.h中声明了UIView和UITableView ivars，并将它们都添加为带有标准"(nonatomic, retain) IBOutlet"标记的属性.在RootViewController.m中，我合成了两者，并添加了代码以在viewDidUnload中将它们设置为nil，然后在dealloc中发布了它们. (试图成为一个好的内存管理公民.)我没有添加任何其他代码.编译时无警告.当我尝试测试该应用程序时，它立即(并反复)崩溃，并显示以下消息:

I declared UIView and UITableView ivars in RootViewController.h, and added them both as properties with the standard "(nonatomic, retain) IBOutlet" tokens; and in RootViewController.m, I synthesized both, and added code to set them to nil in viewDidUnload, and released them in dealloc. (Trying to be a good memory-management citizen.) I haven't added any other code. No warnings on the compile. When I tried to test-drive the app, it crashed immediately (and repeatedly) with the message:

*** Terminating app due to uncaught exception                                       

NSInternalInconsistencyException',
reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the
"RootViewController" nib but the view outlet was not set.'

我已经在我的RootViewController笔尖中将视图和表视图都连接到了文件的所有者；当我在对象图中右键单击文件的所有者"时，我看到它们都被列为出口".右键单击每个控件时，我将文件的所有者视为引用出口.

I have connected both the view and the tableview to the File's Owner in my RootViewController nib; when I right-click on File's Owner in the object graph, I see both of them listed as Outlets. When I right-click each control, I see File's Owner as the Referencing Outlet.

帮助！我该如何解决?

推荐答案

这意味着RootViewController的view属性(继承自UIViewController)未连接到nib文件中的视图.如果右键单击对象图中的文件所有者"，那么您会发现它的view插座已连接到布局中的视图，如所附的屏幕截图所示?

What this means is that the RootViewController's view property (inherited from UIViewController) isn't connected to a view in the nib file. If you right click the File's Owner in the object graph, so you see it's view outlet connected to a view in the layout as in the attached screenshot?

您可以张贴RootViewController.h文件作为对问题的编辑吗?

Can you post your RootViewController.h file as an edit to your question?
