Tab bar + navigation bar
I have two tab bars. In the first tab, I can expand more than three ... but in the second tab, I cannot expand 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?

I didn't understand your code structure, but usually this problem is solved like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
// Initialize UINavigationControllers and push first viewcontrollers for each one
UIViewController *view1 = [[UIViewController alloc] init];
UINavigationController *nav1 = [[UINavigationController alloc] initWithRootViewController:view1];
[view1 release];
// Same for the second NavigationController
...
// Initialize UITabBarController
UITabBarController tController = [[UITabBarController alloc] init];
tController.viewControllers = [NSArray arrayWithObjects:nav1, nav2, nil];
[nav1 release];
[nav2 release];
[window addSubview:tController.view];
...
}
