Question

So, i have a UITabbarController with an UINavigationController in it. On the press of a button, i would like to bring in another UINavigationController, animating it like when using presentModalViewController:animated:, but i do not want it to hide the TabBar.

Is there anything in UIKit (3.1.3 and later) that i could use for this or will i have to do the animating myself?

Just test the code, maybe you need to set the navigationController as property if you need do sth like pushViewController:animated:.

UIViewController * aViewController = [[UIViewController alloc] init];
[aViewController.view setFrame:self.view.frame];
[aViewController.view setBackgroundColor:[UIColor redColor]];

UINavigationController * navigationController = [[UINavigationController alloc] initWithRootViewController:aViewController];
[aViewController release];
[navigationController.view setFrame:CGRectMake(0.0f, 480.0f, 320.0f, 480.0f)];
[self.navigationController.view addSubview:navigationController.view];

[UIView animateWithDuration:0.3f
                      delay:0.0f
                    options:UIViewAnimationOptionCurveLinear
                 animations:^{
                     [navigationController.view setFrame:CGRectMake(0.0f, 0.0f, 320.0f, 480.0f)];
                 }
                 completion:nil];
[navigationController release];
