I am working on xcode4.3.2 and I have created tabbed Application 7 now i want to add navigation controller to it, can somebody help me???
In the applicationDidFinishingLoading of your AppDelegate:
UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
UINavigationController *myNav1=[[UINavigationController alloc] initWithRootViewController:viewController1];
UINavigationController *myNav2=[[UINavigationController alloc] initWithRootViewController:viewController2];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:myNav1, myNav2, nil];
self.window.rootViewController = self.tabBarController;
they're lots of tutorial on Internet but here some issue :
Start to create your tabbed application
At every "1st view" of any tabs :
Editor / Embed - in / Navigation Controller

I used tabbed application template to start my new iPhone project.
I will have 4 tabs.
And I want to nave navigation bar at the top.
So I added this in AppDelegate:
UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
UINavigationController *navigationcontroller = [[UINavigationController alloc] initWithRootViewController:viewController1];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navigationcontroller, viewController2, nil];
And this added navigation bar only at the top of the first ViewController (first tab).
What I want is to add navigation bar for the whole application not just in one view.
This will enable me to jump from one view to another and back across tabs.
So what is the best way to programmatically make one navigation bar for all tab views?
UPDATE
Basically my main question is should I have one navigation bar for all views or each tab should have its own navigation bar?
What is best practice in "iDevelopers" world.
I'd rather have the self.window.rootViewController be a navigationController, and afterwards, just push your tabBarController or
NSMutableArray *viewControllers = [[NSMutableArray alloc] init];
// create someViewController
[viewControllers addObject:someView];
// create someViewController2
[viewControllers addObject:someView2];
UITabBarController *tabController = [[UITabBarController alloc] init];
[tabController setViewControllers:viewControllers];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:tabController]
self.window.rootViewController = navController;
If you want to have navigation bars on each controller, you should to have UINavigationController on each tab of your UITabBarController
Look an answer to this question.
You you need navigation bar you have to add UINavigationController as you did for each view controller in tab bar. So self.tabBarController.viewControllers will have all navigation controllers.
Its not good idea to switch across tabs without user intervention.
I still new to iphone app. dev. , I create navigation based application , with uiNavigationController , the problem is when i selected nav controller and set the bottom bar to tabs there is no tabs appear , also when i add uitabcontroller there is no tab appear .
How to add tabs to UINavigationController using mainwindow.xib ? links , tutorials or any suggestion ?
Here's a sample code for creating a tabBarController with two controllers as tabs:
myTabBarController = [[UITabBarController alloc] init];
NewsFeedController * newsFeedController = [[NewsFeedController alloc] initWithFacebook:facebook];
UINavigationController * navigationControllerHome = [[UINavigationController alloc] initWithRootViewController:newsFeedController];
[newsFeedController release];
AboutController * aboutController = [[AboutController alloc] init];
UINavigationController * navigationControllerAbout = [[UINavigationController alloc] initWithRootViewController:aboutController];
[aboutController release];
myTabBarController.viewControllers = [NSArray arrayWithObjects:navigationControllerHome, navigationControllerAbout, nil];
[self.window addSubview:myTabBarController.view];
Hihi all,
I am pretty new in iPhone dev. I have follow some tutorial and created a tabbar application. Below is the code in the appdelegate implementation:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController *viewController1 = [[ViewController1 alloc] initWithNibName:#"ViewController1" bundle:nil];
UIViewController *viewController2 = [[ViewController2 alloc] initWithNibName:#"ViewController2" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
Then set the title and the image for the tab in each of the controller implementation.
My problem is that, example, in my viewController1, I need to navigate to viewController3, when I use presentModalViewController method to push the viewController3 in, the tabbar at the bottom will be disappeared.
While I tried to use the app delegate to refer to my tabBarController, and use tabBarController.navigationController pushViewController method, my viewController3 is not being pushed, and seems nothing happens.
I have tried to follow a few tutorial, but it's all required to drag in the navigationcontroller into the MainWindow.xib, which, in the xcode 4, MainWindow.xib doesn't exist anymore. How can i create the navigationcontroller from code so that the app can navigate between different view without hiding the tabbar?
Any comment is very much appreciated! Thanks in advance!
:)
If you want to use a navigation controller, you need to create a navigation controller. Since you're not using a XIB, you'll have to create it manually.
Since you want the tab bar to remain visible when you present viewController3, you need to make the navigation controller a child of the tab bar controller.
UIViewController *viewController1 = [[ViewController1 alloc] initWithNibName:#"ViewController1" bundle:nil];
UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
UIViewController *viewController2 = [[ViewController2 alloc] initWithNibName:#"ViewController2" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:
navController1,
viewController2,
nil];
Then when you want to present viewController3, do this:
// in some method of viewController1
[self.navigationController pushViewController:viewController3 animated:YES];
I am not very Sure but have you tried this??? Actually i am going to use XCode 4 soon, i am still using 3.2.8 version:-
WebViewController *viewController = [[WebViewController alloc]initWithNibName:#"WebViewController" bundle:nil];
viewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:viewController animated:YES];
[viewController release];
See in this also the Tab bar will be removed when you navigate to your 3rd screen, you have to provide the navigation bar to come back.
Hope it helps.. :)
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.

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.
I am new to iphone development.I have created a view based application.Now i want tab bar in that view.The first view of the tab bar is a table view and the second view is the Web-view.All the tutorials explain only tab bar based application.Since i am using view based application i finding it really hard.How to achieve it by using interface builder.please guide me.Any Sample tutorials will be more useful.Please help me out.Thanks.
Try this one. This code for created a tab bar application in programmatically. So clicked the button it will open the tab bar in the view.
-(IBAction) clkBtn:(id) sender
{
UITabBarController *tabbar1 = [[UITabBarController alloc] init];
firstViewController *first = [[firstViewController alloc] initWithNibName:#"firstViewController" bundle:nil];
UINavigationController *tabItem1 = [[[UINavigationController alloc] initWithRootViewController: first] autorelease];
secondViewController *second = [[secondViewController alloc] initWithNibName:#"secondViewController" bundle:nil];
UINavigationController *tabItem2 = [[[UINavigationController alloc] initWithRootViewController: second] autorelease];
tabbar1.viewControllers = [NSArray arrayWithObjects:tabItem1, tabItem2,nil];
[self.view insertSubview:tabbar1.view belowSubview: first.view];
[self presentModalViewController:tabbar1 animated:YES];
}
Thanks,
Best of Luck.
