Add UINavigationController to subview on iPhone

Question

I have been trying to add this UINavigationController to a subview of my form... All I am getting is a large grey screen.

LiteViewController *lite = [[LiteViewController alloc] initWithNibName:@"LiteViewController" bundle:nil];
[self.view addSubview:lite.navigationController.view];

It should add a full screen navigation controller to the current view.

Answer 1

I found a post, UINavigationController not showing the Root View controller , that worked for me.

Basically you also need to set the view of the navigationController...

[self.view addSubview:navigationController.view];
[navigationController setView:[[navigationController.viewControllers objectAtIndex:0] view]];

您可能需要makeKeyAndVisible调用。
