Question

I am a little confused about the management for UINavigationController to ModelView. I am having an UINavigationController in the RootView, and I want to popup another modelView from bottom to up based on RootView and in the meanwhile keep the NavigationController stays in the modelView so that I could still navigate to the next. How to implement that?

Answer 1

you can create your navigation controller in the RootView. Suppose you want to display modal view on button click in RootView :

- (IBAction) showModalView
{
        YourModalView * aYourModalView = [[YourModalView alloc] initWithNibName:@"YourModalView" bundle:nil];
        UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:aYourModalView];
        aYourModalView.navigationController.navigationBar.hidden = YES ;

        [self.navigationController presentModalViewController:navigation animated:YES];
        [aYourModalView release];
}

Now, your modal view has navigation controller and you can push VCs from modal view using :

[self.navigationController pushViewController:aViewController animated:YES];

Hope it helps you…
