Tab bar + Navigation Bar

Question

I have a two tab bar,In first tab ,i can drill down more than three... but in second tab i cannot drill down more than one.. Any ideas?

code: DemoAppdelegate.m

- (void)applicationDidFinishLaunching:(UIApplication *)application {
[window addSubview:tabBarController.view];
}

First tab controller is "FirstViewController"
in FirstViewController.m i have written to drill down to "billsummary.xib" 


DemoAppDelegate *app = (DemoAppDelegate *)[[UIApplication sharedApplication] delegate];
    UINavigationController *naviController = app.navigationController;
    BillsSummary *aViewAController = [[BillsSummary alloc] initWithNibName:@"BillsSummary" bundle:[NSBundle mainBundle]];

    [naviController pushViewController:aViewAController animated:YES];
    [aViewAController release];

which is working fine.But same code for in second tab for another .xib is not working and in second tab i have not used appdelegate instead i used "self.navigationcontroller"

UINavigationController *naviController = self.navigationController;
    PaymentsAmount *aViewAController = [[PaymentsAmount alloc] initWithNibName:@"PaymentsAmount" bundle:[NSBundle mainBundle]];

    [naviController pushViewController:aViewAController animated:YES]; 
    [aViewAController release];

what to do? Any help please?

Answer 1

What file does your second code snippet live in? It might be that self.navigationController doesn't refer to the navigation controller you think it does.
