I am trying to add Navigation bar to my tabbar view controllers.But, it is showing up in firstViewController but not in the other two views. Any reason why this is not working?
self.firstVC = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil fileName:#"firstPlist"];
self.firstVC.tabBarItem.image = [UIImage imageNamed:#"first"];
self.firstNavBarController = [[UINavigationController alloc] initWithRootViewController:self.firstVC];
self.secondVC = [[FirstViewController alloc] initWithNibName:#"SecondViewController" bundle:nil fileName:#"secondPlist"];
self.secondVC.tabBarItem.image = [UIImage imageNamed:#"second"];
self.secondNavBarController = [[UINavigationController alloc] initWithRootViewController:self.secondVC];
self.thirdVC = [[ThirdViewController alloc] initWithNibName:#"thirdView" bundle:nil fileName:#"thirdPlist"];
self.thirdVC.tabBarItem.image = [UIImage imageNamed:#"third"];
self.thirdNavBarController = [[UINavigationController alloc] initWithRootViewController:self.thirdVC];

I have a TabBarController with 4 Tab. When i push a ViewController from a tab then the tab is hidden automatically and its showing nothing in View. But ViewController contains a tableview with data. I have implemented tableview delegate also.I am not getting tableview delegate logs.
in appdelegate didFinishLaunchingWithOptions()
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.homeScreen = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
self.rootNav = [[UINavigationController alloc]initWithRootViewController:self.homeScreen];
self.window.rootViewController = self.rootNav;
[self.window makeKeyAndVisible];
Load TabBar here:
myAppDelegate.myTabBarController.selectedIndex = 0;
myAppDelegate.myTabBarController.tabBar.translucent = NO;
myAppDelegate.myTabBarController.tabBar.opaque = YES;
location_select *tab1 = [[location_select alloc] initWithNibName:#"location_select" bundle:nil];
tab1.tabBarItem.image = [UIImage imageNamed:#"Restaurants.png"];
location_select *tab2 = [[location_select alloc] initWithNibName:#"location_select" bundle:nil];
tab2.title = #"Cart";
tab2.tabBarItem.image = [UIImage imageNamed:#"Cart.png"];
Deal_ViewController *tab3 = [[Deal_ViewController alloc] initWithNibName:#"Deal_ViewController" bundle:nil];
tab3.title = #"Deals";
tab3.tabBarItem.image = [UIImage imageNamed:#"Deals.png"];
MoreViewController *tab4 = [[MoreViewController alloc] initWithNibName:#"MoreViewController" bundle:nil];
tab4.title = #"More";
tab4.tabBarItem.image = [UIImage imageNamed:#"More.png"];
myAppDelegate.myTabBarController.viewControllers = [NSArray arrayWithObjects:tab1,tab2,tab3,tab4,nil];
[myAppDelegate.rootNav pushViewController:myAppDelegate.myTabBarController animated:YES];
From Tab 4, i push Profile_ViewController:
Profile_ViewController *vc = [[Profile_ViewController alloc] initWithNibName:#"Profile_ViewController" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:vc animated:YES];
And already i applied there:
myAppDelegate.myTabBarController.hidesBottomBarWhenPushed=NO;
and
[self.tabBarController setHidesBottomBarWhenPushed:NO];
in viewWillAppear of Profile_ViewController. Nothings works. I just see a blank white screen.
location_select *tab1 = [[location_select alloc] initWithNibName:#"location_select" bundle:nil];
tab1.tabBarItem.image = [UIImage imageNamed:#"Restaurants.png"];
location_select *tab2 = [[location_select alloc] initWithNibName:#"location_select" bundle:nil];
tab2.title = #"Cart";
tab2.tabBarItem.image = [UIImage imageNamed:#"Cart.png"];
Deal_ViewController *tab3 = [[Deal_ViewController alloc] initWithNibName:#"Deal_ViewController" bundle:nil];
tab3.title = #"Deals";
tab3.tabBarItem.image = [UIImage imageNamed:#"Deals.png"];
MoreViewController *tab4 = [[MoreViewController alloc] initWithNibName:#"MoreViewController" bundle:nil];
tab4.title = #"More";
tab4.tabBarItem.image = [UIImage imageNamed:#"More.png"];
UINavigationController *nav1 = [[UINavigationController alloc] initWithRootViewController:tab1];
UINavigationController *nav2 = [[UINavigationController alloc] initWithRootViewController:tab2];
UINavigationController *nav3 = [[UINavigationController alloc] initWithRootViewController:tab3];
UINavigationController *nav4 = [[UINavigationController alloc] initWithRootViewController:tab4];
myAppDelegate.myTabBarController.viewControllers = [NSArray arrayWithObjects:nav1,nav2,nav3,nav4,nil];
[myAppDelegate.rootNav pushViewController:myAppDelegate.myTabBarController animated:YES];
and then later on to push your vc to tab 4 you should do
Profile_ViewController *vc = [[Profile_ViewController alloc] initWithNibName:#"Profile_ViewController" bundle:[NSBundle mainBundle]];
[nav4 pushViewController:vc animated:YES];
here is the Solution related to your query which might help you
You might have kept your architecture as follows
Navigation Controller ---> Tab bar Controller --> 4 child View Controllers
You need to do this
Tab bar Controller --> 4 Child controllers(Each of these 4 child View Controller having its own Navigation Controller).
What is the best practice or good way to have with 2 tabs behave like a UINavigationController when clicking through views after the tab bar views.
Do I make a UINavigationController for each tab?
The tab bar is created like so:
// Create the tab bar text and images
AViewController *viewA = [[AViewController alloc] init];
BViewController *viewB = [[BViewController alloc] init];
UITabBarItem *tabA = [[UITabBarItem alloc] initWithTitle:#"A" image:[UIImage imageNamed:#"a.png"] tag:1];
UITabBarItem *tabB = [[UITabBarItem alloc] initWithTitle:#"B" image:[UIImage imageNamed:#"b.png"] tag:2]
viewA.tabBarItem = tabA;
viewB.tabBarItem = tabB;
NSArray* controllers = [NSArray arrayWithObjects:viewA, viewB, nil];
self.viewControllers = controllers;
For navigation you need to create UINavigationController for each like this
Updated : Try now
AViewController *viewA = [[AViewController alloc] init];
BViewController *viewB = [[BViewController alloc] init];
UINavigationController *navA = [[UINavigationController alloc]initWithRootViewController:viewA];
UINavigationController *navB = [[UINavigationController alloc]initWithRootViewController:viewA];
UITabBarItem *tabA = [[UITabBarItem alloc] initWithTitle:#"A" image:[UIImage imageNamed:#"a.png"] tag:1];
UITabBarItem *tabB = [[UITabBarItem alloc] initWithTitle:#"B" image:[UIImage imageNamed:#"b.png"] tag:2]
tabA.tabBarItem = tabA;
tabB.tabBarItem = tabB;
NSArray* controllers = [NSArray arrayWithObjects:navA, navB, nil];
self.viewControllers = controllers;
Try this
I am unable to get the navigation bar to show the title that I specify. I have tried to change the title in the AppDelegate.m, as well as in the viewDidLoad of my first tab view. I suspect the title is being hidden, but I am unable fix it. Please provide any insight you may have.

The relationship of your view controllers isn't right.
The root view controller of your app should be the TabBarController.
Each of the items should have it's own Navigation Controller.
The title of each ViewController can be set in viewDidLoad() with self.title = "....
I've been able to set titles in the delegate as follows:
1.) Create view controllers
2.) Set those titles
3.) Then create UINavigationControllers and assign view controllers there
self.firstViewController = [[FirstViewController alloc] initWithNibName:nil bundle:nil];
self.secondViewController = [[SecondViewController alloc] initWithNibName:nil bundle:nil];
self.thirdViewController = [[ThirdViewController alloc] initWithNibName:nil bundle:nil];
self.fourthViewController = [[FourthViewController alloc] initWithNibName:nil bundle:nil];
[self.firstViewController setTitle:#"First"];
[self.secondViewController setTitle:#"Second"];
[self.thirdViewController setTitle:#"Third"];
[self.fourthViewController setTitle:#"Fourth"];
UINavigationController *controller1 = [[UINavigationController alloc] initWithRootViewController:self.firstViewController];
UINavigationController *controller2 = [[UINavigationController alloc] initWithRootViewController:self.secondViewController];
UINavigationController *controller3 = [[UINavigationController alloc] initWithRootViewController:self.thirdViewController];
UINavigationController *controller4 = [[UINavigationController alloc] initWithRootViewController:self.fourthViewController];
NSArray *viewControllers = [NSArray arrayWithObjects:controller1, controller2, controller3, controller4, nil];
I am relative new with the iOS app development. Currently I am developing a small app with a tab bar. The problem I am facing is that I would like to have different navigation items foreach tab. I tried a lot of things, but things aren't working. I am programming in the native iOS language.
In my app I've got a AppDelegate. In my AppDelegate there is a little piece of code for setting up my mainViewController:
- (void)setupOverlordViewController
{
MainViewController *rootVC = [[MainViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navVC = [[UINavigationController alloc] initWithRootViewController:rootVC];
self.window.rootViewController = navVC;
}
I am setting up my tabs in my MainViewController:
- (void)viewDidLoad
{
UIViewController *tabView1 = [[Tab1ViewController alloc] init];
UIViewController *tabView2 = [[Tab2ViewController alloc] init];
UIViewController *tabView3 = [[Tab3ViewController alloc] init];
NSMutableArray *tabViewControllers = [[NSMutableArray alloc] init];
[tabViewControllers addObject:tabView1];
[tabViewControllers addObject:tabView2];
[tabViewControllers addObject:tabView3];
[self setViewControllers:tabViewControllers];
tabView1.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"TabView1", nil)
image:[UIImage imageNamed:#"tabView1.png"]
tag:1];
tabView2.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"TabView2", nil)
image:[UIImage imageNamed:#"tabView2.png"]
tag:2];
tabView3.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"TabView3", nil)
image:[UIImage imageNamed:#"tabView3.png"]
tag:3];
}
Each View (tabView1, tabView2, tabView3) has there own layout, which is set in the ViewDidLoad method of the View. When I would like to add navigation buttons in the navigation bar by adding them in the ViewDidLoad method, but it seems impossible to add the buttons. The only way to add them is directly in my MainViewController, but then I can't set the navigation bar buttons different foreach tab.
The code for adding the buttons to my navigation bar is as follows:
UIBarButtonItem *btnNewRecord = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(btnNewRecord)];
NSArray *rightItems = [NSArray arrayWithObjects:btnNewRecord, nil];
[self.navigationItem setRightBarButtonItems:rightItems];
Could somebody explain me what I am doing wrong?
I have created a example for you by using xib files. I have created three View Controllers and added them to navigation controllers. Following the appdelegate code :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
FirstViewController *firstVC = [[FirstViewController alloc] initWithNibName:#"FirstView" bundle:nil];
UINavigationController *firstNavVC = [[UINavigationController alloc] initWithRootViewController: firstVC];
SecondViewController *secondVC = [[SecondViewController alloc] initWithNibName:#"SecondView" bundle:nil];
UINavigationController *secondNavVC = [[UINavigationController alloc] initWithRootViewController: secondVC];
ThirdViewController *thirdVC = [[ThirdViewController alloc] initWithNibName:#"ThirdView" bundle:nil];
UINavigationController *thirdNavVC = [[UINavigationController alloc] initWithRootViewController: thirdVC];
NSMutableArray *tabViewControllers = [[NSMutableArray alloc] init];
[tabViewControllers addObject:firstNavVC];
[tabViewControllers addObject:secondNavVC];
[tabViewControllers addObject:thirdNavVC];
firstNavVC.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"First", nil)
image:nil
tag:1];
secondNavVC.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"Second", nil)
image:nil
tag:2];
thirdNavVC.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"Third", nil)
image:nil
tag:3];
UITabBarController *tabbarController = [[UITabBarController alloc] init];
tabbarController.viewControllers = tabViewControllers;
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.rootViewController = tabbarController;
[self.window makeKeyAndVisible];
return YES;
}
Following is the output :
You can download code example here
you need separate navigation controller for each tab bar view controller & then you can add UIBarButtonItem on each navigation controller.
I've been following lot's of different tutorials on how to add a UITabBarController programmatically. This would be easy to achieve using storyboard, but since I'm trying to learn how to do things programmatically I can't do that.
At the moment I've got this code in the didFinishLaunchingWithOptions.
tabBarController = [[UITabBarController alloc] init];
NSMutableArray *tabs = [[NSMutableArray alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:[[MenuViewController alloc] init]];
[tabBarController setViewControllers:tabs];
[tabs addObject:navController];
[self.window addSubview:tabBarController.view];
Edited code:
tabBarController = [[UITabBarController alloc] init];
MenuViewController *firstTab = [[MenuViewController alloc] initWithNibName:#"MenuViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:firstTab];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = #[navController];
[self.window setRootViewController:tabBarController];
[self.window makeKeyAndVisible];
This does not do anything to my rootViewController called MenuViewController. How can I achieve this?
Thie bellow code for 5 tab UITabbarcontroller try with this bellow code:-
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
anasayfaViewController * firstTab= [[anasayfaViewController alloc] initWithNibName:#"anasayfaViewController" bundle:nil];
UINavigationController *navigationController1 = [[UINavigationController alloc] initWithRootViewController:firstTab];
SehirRehberiViewController *sehirRehberi = [[SehirRehberiViewController alloc] initWithNibName:#"SehirRehberiViewController" bundle:nil];
UINavigationController *navigationController2 = [[UINavigationController alloc] initWithRootViewController:sehirRehberi];
duyuruViewController *duyuru = [[duyuruViewController alloc] initWithNibName:#"duyuruViewController" bundle:nil];
UINavigationController *navigationController3 = [[UINavigationController alloc] initWithRootViewController:duyuru];
sikayetViewController *sikayet = [[sikayetViewController alloc] initWithNibName:#"sikayetViewController" bundle:nil];
UINavigationController *navigationController4 = [[UINavigationController alloc] initWithRootViewController:sikayet];
digerViewController *diger = [[digerViewController alloc] initWithNibName:#"digerViewController" bundle:nil];
UINavigationController *navigationController5 = [[UINavigationController alloc] initWithRootViewController:diger];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = #[navigationController1,navigationController2,navigationController3,navigationController4,navigationController5];
[self.window setRootViewController:tabBarController];
[self.window makeKeyAndVisible];
You should add tab bar controller as a root view controller:
[self.window setRootViewController:tabBarController];
also it's a good idea to first add object to array and after that do something with it, (other way round):
[tabs addObject:navController];
[tabBarController setViewControllers:tabs];
UIViewController *viewController_favorites = [[[FavoritesViewController alloc] initWithNibName:#"FavoritesViewController" bundle:nil] autorelease];
UIViewController *viewController_project = [[[ProjectViewController alloc] initWithNibName:#"ProjectViewController" bundle:nil] autorelease];
UIViewController *viewController_search = [[[Search alloc] initWithNibName:#"Search" bundle:nil] autorelease];
UIViewController *viewController_setting = [[[SettingViewController alloc] initWithNibName:#"SettingViewController" bundle:nil] autorelease];
UINavigationController *navController_favorite = [[[UINavigationController alloc] initWithRootViewController:viewController_favorites] autorelease];
UINavigationController *navController_project = [[[UINavigationController alloc] initWithRootViewController:viewController_project] autorelease];
UINavigationController *navController_search = [[[UINavigationController alloc] initWithRootViewController:viewController_search] autorelease];
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController_favorite,navController_project,navController_search,viewController_setting, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
If you want to have a UITabBarController as your app's rootViewcontroller you can add this code to the didFinishLaunchingWithOptions function.
It adds a navigation controller containing a list controller and a simple view controller:
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
UITabBarController* tabBarController = [[UITabBarController alloc] init];
UITableViewController* myListController = [[MyListController alloc] init];
UINavigationController* navigationControllerMyList = [[UINavigationController alloc] initWithRootViewController:myListController];
navigationControllerMyList.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemFavorites tag:0];
UIViewController* simpleViewController = [[SimpleViewController alloc] init];
simpleViewController.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemContacts tag:0];
tabBarController.viewControllers = #[ navigationControllerMyList , simpleViewController ];
self.window = [[UIWindow alloc] init];
self.window.rootViewController = tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
