DO I need to pop any viewController before I push the third viewController?

Thanks!

Getting this from View2ViewController.nib, probably the reason I can’t find View2ViewController in the View2.xib drop down list.

I believe this could be accomplished with on view controller, and six nib files? I just don’t know how – Any comments you might make as to an approach would be welcomed.

    if(self.view2ViewController == nil){
    
        View2ViewController *view2 = [[View2ViewController alloc] initWithNibName:nil bundle: nil];
        self.view2ViewController = view2;
        [view2 release];
    }
