I have a problem building applicatin with tabBarController. There is no problem doing tabBarController with navigationController if I build it from AppDelegate.

But now I have experienced problem when I want to create new view with tabBarController (3 tabs and each has navigation controllers) after a push from previous navigation controller. It simply doesnt work.

Here is the code:

MainViewController *mainViewController = [[MainViewController alloc] initWithNibName:@"MainView_iPhone" bundle:nil];
mainViewController.tabBarItem.title = @"First";
UINavigationController *mainNavigationController = [[UINavigationController alloc] initWithRootViewController:mainViewController];

DictionariesViewController *dictionariesViewController = [[DictionariesViewController alloc] initWithNibName:@"DictionariesView_iPhone" bundle:nil];
dictionariesViewController.tabBarItem.title = @"Second";
UINavigationController *dictionariesNavigationController = [[UINavigationController alloc] initWithRootViewController:dictionariesViewController];

tabBarController = [[UITabBarController alloc] init];
tabBarController.viewControllers = [NSArray arrayWithObjects:mainNavigationController, dictionariesNavigationController, nil];

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

There is a problem after view is pushe to "First" controller. Application crashes...

Please for help.

Regards Borut

Please reformat your code. It's hard to read the code as is :) – ryanprayogo

What are you trying to do with the following code?

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

You said that your app has 3 tabs and each of those tabs have a navigation controller. Therefore, what you should do is to add the navigation controllers to tabBarController.viewControllers (which you did), but then you need to set the tabBarController as the root view controller.

I have done it this way and it works:

registerViewController = [[RegisterViewController alloc] initWithNibName:@"RegisterView_iPhone" bundle:nil];
AppDelegate_Phone *delegatePhone = [[UIApplication sharedApplication] delegate];
[delegatePhone.firstViewController.navigationController pushViewController:registerViewController animated:YES];

Thanks for your help guys.
