NSInternalInconsistencyException on RootViewController

Question

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.

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.'

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.

Help! How do I fix this?

Answer 1

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?

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

您只需要将xib中的默认视图连接到文件所有者。
