Question

I am breaking the normal paradigm of a UINavigationController, or at least I’m trying to.

We know that the Navigation Controller manages navigation via a stack. If I initialize with root controller A, navigate to B, and then Navigate to C, the Stack will look like – C/B/A.

What I want to do though, is have a button on view C that will show another view, say X, but still keep the Navigation Controller’s nav bar in place. Essentially, switch “C” and “X” on the stack. I tried to accomplish that by popping C off and immediately pushing X as shown below, but it didn’t work. Am I going down the wrong path here?

-(IBAction)showViewX:(id)sender {
[[self.parentViewController navigationController] popViewControllerAnimated:NO];

XViewController *xViewController = [[XViewController alloc]
        initWithNibName:@"X" 
        bundle:[NSBundle mainBundle]];
[[self.parentViewController navigationController] pushViewController: xViewController animated:YES];
[xViewController release];  
}

What you call “view C” is actually “view controller C”. Since it is a view controller, you can easily set it up to switch between, say, two views, X and Y. So you just leave C on the stack, don’t pop it, and switch between views in C itself. For example, you can set up C to use a toolbar to switch between views.
