Switching nib files

Question

I have a View Controller inside my MainWindow.xib file that loads the nib "Cover" when loaded. Cover (and the rest of my pages) is simply a nib file containing it's Owner, First Responder and a View. There is also an associated class declaration.

In MainViewController.m I have:

- (void)viewDidLoad {

 [[NSBundle mainBundle] loadNibNamed:@"Cover" owner:self options:nil];
 [super viewDidLoad];
}

This successfully loads the Cover of my app. On a button press I'd like to have a function switch Cover with Page1. I tried:

-(IBAction)funcGoToPage:(id)sender{

 [[NSBundle mainBundle] loadNibNamed:@"Page1" owner:self options:nil];

}

This function is also in MainViewController. I know the function is being called but It doesn't seem to do anything. Is the new nib showing up underneath the current nib? Do I have to release the current nib?

Depending on how you want users to navigate, you either need to add the view of the nib as a subview to your current view, or push a new viewController on to the stack using a navigationController. Here is a tutorial on using a navigationController. Or, if you just want to exchange them, here is a link to a SO answer for just that.
