NavigationController in modal view

[arbi]

Hi,

I've got a modal view which must have a kind of subnavigation. I tried to use a UINavigationController to realize it:

- (void)viewDidLoad
{
[super viewDidLoad];

TestSubviewLeft *leftview = [[TestSubviewLeft alloc] initWithNibName:@"TestSubviewLeft" bundle:nil];
leftview.title = @"Leftview";

TestSubviewLeft *rightview = [[TestSubviewLeft alloc] initWithNibName:@"TestSubviewRight" bundle:nil];
rightview.title = @"Rightview";

NSArray *views = [[NSArray alloc] initWithObjects:leftview, rightview, nil];
_subNavigationController = [[UINavigationController alloc] init ];//WithRootViewController:leftview];
[_subNavigationController setViewControllers:views];

[self.view addSubview:[_subNavigationController view]];
}

The problem is, that my modal view now starts with the second subview (not the first) which has a correct back button. When I click the back button, the first subviews appears, but without a "forward-button" on the right side.

What am I doing wrong?
Thangs for your help.

Im new to this myself but should you not just add the left view to the controller on its own and then else where in your code have something that creates the right view and pushes it to the navigation controller stack when needed?
you can add a button to the right of the first view nav bar with something like this

UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Right"
    style:UIBarButtonSystemItemDone target:nil action:nil];
self.navigationItem.rightBarButtonItem = rightButton;
[rightButton release];

and then within the ibaction for that button have

TestSubviewLeft *rightview = [[TestSubviewLeft alloc] initWithNibName:@"TestSubviewRight" bundle:nil];
rightview.title = @"Rightview";
 [self.navigationController pushViewController:rightview animated:YES];
    [rightview release];

Thanks for your quick answer. I first implemented it by my own navigation bar. But than I'm losing the arrows at the bar buttons. They look like normal buttons
I'm really confused by the navigation controller. If I implement as you suggestet, why do I need the navigation controller

i think that the navigation controller only handles the back button functionality for you as its just a stack but you need to add extra functionality to push new views onto that stack. Now my understanding could be well off so dont shoot me if im wrong :P

Maybe you're right - unfortunately. So I want to explain agein what I need:
I need a submenue to switch between two subviews. And the buttons on the navigation bar should have this style with arrows on the left or right side.

Is this possible without painting special background images?

just seen you can set the style of the button when you create it youself so you can maybe get the button type you want?

Yes, I know that, thank you. But there's no style for forward or back

not sure if this will help as im not sure how you could add it to the nav bar but

UIButton *t = [UIButton buttonWithType:101];
    [someview addSubview:t];

will give you an arrow button. then scale it with -1 in x direction for right facing. Im not able to check if any of that will work at the moment but might be worth having a look at yourself
