I made two applications that each one of them is tabbar based.
Now I want to combine them to one app that will be struct like that:
-Main menu with 2 buttones.
- button 1: tab bar app no 1.
- button 2: tab bar app no 2.
from each tab bar app, I want an Home button on the left side of the nav bar that will take me to the main menu.
I found this link http://www.pushplay.net/blog_detail.php?id=27 but it's not good to me..
I will be happy if you will able to post some simple code for my problem..
Thanks.
App's 1 & 2 need to be based around viewcontrollers, each of which has a tabbar. The root windows can then just alloc/init and then [self.navigationController pushViewController:viewController animated:YES]; to launch the tabbar controller.
If you have relied on IB to build your tabbar applications, its quite difficult to translate them into view controllers. I create my tabbars programatically (i just find it easier) like this
tabBarController = [[UITabBarController alloc] init]; // creates your tab bar so you can add everything else to it
searchTableViewController = [[SearchTableViewController alloc] init];
UINavigationController *searchTableNavController = [[[UINavigationController alloc] initWithRootViewController:searchTableViewController] autorelease];
[searchTableViewController release];
searchMapViewController = [[SearchMapViewController alloc] init];
UINavigationController *mapTableNavController = [[[UINavigationController alloc] initWithRootViewController:searchMapViewController] autorelease];
[searchMapViewController release];
atestViewController = [[AboutTableViewController alloc] init];
UINavigationController *AboutNavController = [[[UINavigationController alloc] initWithRootViewController:atestViewController] autorelease];
[atestViewController release];
tabBarController.viewControllers = [NSArray arrayWithObjects:searchTableNavController, mapTableNavController, AboutNavController, nil];
[self.view addSubview:tabBarController.view];

Basically I have
ViewControllerA *aVC = [[ViewControllerA alloc] init];
ViewControllerB *bVC = [[ViewControllerB alloc] init];
UITabBarController *tabBarVC = [[UITabBarController alloc] init];
[tabBarVC setViewControllers:[[NSArray alloc] initWithObjects:aVC, bVC, nil] animated:YES];
Now I can see the two tabs on the tabBarController but when I switch from one tab to another, I can't see any effects, neither on simulator or on real device. From the documentation I should be able to see fading right? Did I miss anything?
If you pass YES to setViewControllers:animated:, UITabBarController will animate the insertion of the the new tab bar items in the tab bar. It doesn't animate the transition between view controllers if the user then switches from one tab to another.
Hi guys I am working on an application.Where there is a home screen with 5 buttons.On the click of every button i want to open the screen with tabbar with 5 view controllers.I mean when you click on the button the tabbar is opened.And there are back button on the tab bar view as well .On clicking the back button i want to pop back to the home screen and vice versa.
How to do that guys.Any tutorial ,links,sample code would be appreciated.
Thanks a lot to all
Tabbar controller in a navigation stack is complicated. Since each tab controller can have also navigation controller itself.
Have a WindowManager class. It should own both
- FirstViewController and
- TabbarController
All components and the UITabbarControllers themselves should be instantiated in the WindowManager class.
Its init may have code like this, make similar for two tabbarcontrollers.
self.tabBarController = [[UITabBarController alloc] init];
self.controllers = [[NSMutableArray alloc] init];
// initialize the view controllers and navigation controllers for the tab bar
self.friendsVC = [[FriendsVC alloc] initWithNibName:#"FriendsView" bundle:nil];
UINavigationController *friendsNVC = [[UINavigationController alloc] initWithRootViewController: friendsVC];
friendsNVC.navigationBar.barStyle = UIBarStyleBlack;
[controllers addObject:friendsNVC];
[friendsNVC release];
self.paymentsVC = [[PaymentsVC alloc] initWithNibName:#"PaymentsView" bundle:nil];
UINavigationController *paymentsNVC = [[UINavigationController alloc] initWithRootViewController: paymentsVC];
paymentsNVC.navigationBar.barStyle = UIBarStyleBlack;
[controllers addObject:paymentsNVC];
[paymentsNVC release];
tabBarController.viewControllers = controllers;
tabBarController.selectedIndex = 0;
tabBarController.delegate = self;
self.view = tabBarController.view;
In the WindowManager, you can have two methods like,
[WindowManager showViewController] and
[WindowManager showTabbarController].
- showViewController {
//Initiate View controller and use [self.window addSubView:vc.view];
}
- showTabbarController {
// initiate the tabbar manager
}
You can have a "back" button on top of your first tabbar controller left side, to call the
[WindowManager showViewController];
I currently have a UINavigationController in my app delegate where I push a ViewController on to login. If the login is successful I want to then create a UITabBarController with a Navigation Controller as the first Tab whose root controller is a UIViewController that I am creating.
The RootViewController of my first UINavigationController is actually acting as a delegate to the logincontroller so if a user logs in correctly it calls a method in my RootViewController which is where I would then like to push a UITabBarController onto the stack. Here is my code:
UITabBarController *tbController = [[UITabBarController alloc] init];
FileBrowserViewController *fileController = [[FileBrowserViewController alloc] init];
fileController.pathToFileDB = pathToDBUnzipped;
fileController.parentId = #"0";
UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:fileController];
NSMutableArray *aViewControllersArray = [[NSMutableArray alloc] initWithCapacity:2];
[aViewControllersArray addObject:navController];
[navController release];
[tbController setViewControllers:aViewControllersArray];
[self.navigationController pushViewController:tbController animated:YES];
[tbController release];
Now, it is all working fine. Except 2 things. Here is the screen shot:
1) I can't see any uitabbar items. How do i set an image and the text for each tab?
2) I don't want that top black bar. I only want 1 bar ontop with the undo button. How do I remove the additional bar?
I always follow this approach when I have both a UINavigationController and a UITabbarController:
You need to start with a view based application. And then create a UITabbarController in your appDelegate file.
Appdelegate.h
UITabBarController *tabBarController;
// set properties
Appdelegate.m
// Synthesize
tabBarController = [[UITabBarController alloc] init];
tabBarController.delegate=self;
// Adding Search,Nearby,Map,AboutUs,Favorites Tabs to tabBarController
Search * search = [[Search alloc] init];
UINavigationController *searchNav = [[UINavigationController alloc] initWithRootViewController:search];
Nearby* nearby = [[Nearby alloc] init];
UINavigationController *nearbyNav = [[UINavigationController alloc] initWithRootViewController:nearby];
Map* map = [[Map alloc] init];
UINavigationController *mapNav = [[UINavigationController alloc] initWithRootViewController:map];
AboutUs* aboutUs = [[AboutUs alloc] init];
UINavigationController *aboutUsNav = [[UINavigationController alloc] initWithRootViewController:aboutUs];
Favorites* favorites = [[Favorites alloc] init];
UINavigationController *favoritesNav = [[UINavigationController alloc] initWithRootViewController:favorites];
NSArray* controllers = [NSArray arrayWithObjects:searchNav,nearbyNav,mapNav,aboutUsNav,favoritesNav, nil];
tabBarController.viewControllers = controllers;
[window addSubview:tabBarController.view];
You can accordingly manage in which tab you want to place navigation controller or only a view controller.
Then in each of the view controllers mentioned above you need to implement
- (id)init {}
in which you can set Tab name and image.
I always follow this approach and it never fails. The tabs are always visible. You can make changes according to your code.
to hide the above black bar use -
[self.navigationController setNavigationBarHidden:TRUE];
to set tab bar item use -
for system item -
UITabBarItem *firstItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemFavorites tag:0];
for custom item -
UITabBarItem *firstItem = [[UITabBarItem alloc] initWithTitle:#"title" image:[UIImage imageNamed:#""] tag:0];
[navController setTabBarItem:firstItem];
Here is a good video on how to combine Tab Bar, Navigation Bar, and/or Table Views.

If you don't want you sign-up screen to have a Tab Bar controller, then you will have to present it as a modal view (since the tab bar is your root view controller). This can be done through the presentModalViewController:animated: method. You can find info about that at:
http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/ModalViewControllers/ModalViewControllers.html%23//apple_ref/doc/uid/TP40007457-CH111-SW1
I hope that helps. Let me know if you have any other questions!
Cheers, Evan.
hi friend that top bar is status bar . You can set.statusbar hidden = yes;
or change it from plist , when you open your plist there is a option to hide it,
I have developed a tab based iphone application.
In this, I am facing a problem as described below:
The view associated with 1st tab bar contains 2-3 buttons. Action of these buttons are to load another view. Now on pressing these buttons the views are loading but in full size(320x480) and hiding the tab bar.
I want to load that view just above the tab bar so that tab bar is accessible.
I explicitly set the view frame in that view's viewDidLoad function, but it is not working.
Please help me out.
Try this :
You need to start with view based application. And then create a UITabbarController in you appDelegate file.
Appdelegate.h
UITabBarController *tabBarController;
// set properties
Appdelegate.m
// Synthsize
tabBarController = [[UITabBarController alloc] init];
tabBarController.delegate=self;
//Adding Search,Nearby,Map,AboutUs,Favorites Tabs to tabBarController
Search * search = [[Search alloc] init];
UINavigationController *searchNav = [[UINavigationController alloc] initWithRootViewController:search];
Nearby* nearby = [[Nearby alloc] init];
UINavigationController *nearbyNav = [[UINavigationController alloc] initWithRootViewController:nearby];
Map* map = [[Map alloc] init];
UINavigationController *mapNav = [[UINavigationController alloc] initWithRootViewController:map];
AboutUs* aboutUs = [[AboutUs alloc] init];
UINavigationController *aboutUsNav = [[UINavigationController alloc] initWithRootViewController:aboutUs];
Favorites* favorites = [[Favorites alloc] init];
UINavigationController *favoritesNav = [[UINavigationController alloc] initWithRootViewController:favorites];
NSArray* controllers = [NSArray arrayWithObjects:searchNav,nearbyNav,mapNav,aboutUsNav,favoritesNav, nil];
tabBarController.viewControllers = controllers;
[window addSubview:tabBarController.view];
You can accordingly manage in which tab you want to place navigation controller or only a view controller.
Then in each of the view controllers mentioned above you need to implement
- (id)init {}
in which you can set Tab name and image.
Rename the tbs as per your requirement. Place 2 buttons in the one of the views which is Navigation controller.
Hope this helps.
Typical application navigation allows the user to freely move forwards and backwards, between tabs etc. This is facilitated by pushing and popping ViewController's on the navigation bar stack.
In certain scenarios you want to force the user to complete some task and this is when you should use a modal view controller. When the application presents a modal view the idea is that the user should NOT be able to navigate away from the view, instead they should only be able to complete or cancel the action and hence the default behavior for a modal view is to hide the navigation bar, tab bar etc.
It sounds to me from your description that you are performing navigation and not a modal task and thus can I recommend using pushViewController instead of presentModalViewController?
If you are only using presentModalViewController because you want a bottom to top animation then you'll need to use a custom animation.
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.
