Following is my code and it is showing tab bar only on given 2 tab bar items but it is not showing tab bar in other views.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.startQuizViewController = [[StartQuizViewController alloc] initWithNibName:nil bundle:nil];
self.scoreViewController = [[ScoreViewController alloc] initWithNibName:nil bundle:nil];
self.startQuizViewController.title = #"QUIZ";
self.scoreViewController.title = #"SCORES";
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:self.startQuizViewController,self.scoreViewController,nil];
_navigationController=[[UINavigationController alloc]initWithRootViewController:self.tabBarController];
[self.window addSubview:self.navigationController.view];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
return YES;
code in written in didFinishLaunchingWithOptions in AppDelegate.m.
change this part:
_navigationController=[[UINavigationController alloc]initWithRootViewController:self.tabBarController];
[self.window addSubview:self.navigationController.view];
self.window.rootViewController = self.navigationController;
to this:
self.window.rootViewController = self.tabBarController;
you cannot have tabbarcontroller inside a navigation controller. so just remove navigation controller and set tab bar controller as root view controller
edit:
self.startQuizViewController = [[StartQuizViewController alloc] initWithNibName:nil bundle:nil];
self.scoreViewController = [[ScoreViewController alloc] initWithNibName:nil bundle:nil];
self.startQuizViewController.title = #"QUIZ";
self.scoreViewController.title = #"SCORES";
self.tabBarController = [[UITabBarController alloc] init];
UINavigationController * nav1 = [[UINavigationController alloc] initWithRootViewController:self.startQuizViewController];
UINavigationController * nav2 = [[UINavigationController alloc] initWithRootViewController:self.scoreViewController];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:nav1, nav2, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
that's it. you can now push view controller inside those controller and can have the tab bar always there.
Use this
UIViewController *viewController1, *viewController2;
viewController1 = [[UIViewController alloc] initWithNibName:#"FirstViewController" bundle:nil] ;
UINavigationController *navigationcontroller = [[UINavigationController alloc] initWithRootViewController:viewController1] ;
viewController2 = [[UIViewController alloc] initWithNibName:#"SecondViewController" bundle:nil] ;
UINavigationController *navigationcontroller2 = [[UINavigationController alloc] initWithRootViewController:viewController2] ;
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navigationcontroller, navigationcontroller2, nil];
and finally
self.window.rootViewController = self.tabBarController;
This way you have seperate navigation controllers for both tabbar controller.

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'm having an LoginViewController which is the RootViewController. This ViewController should not have the TabBar included. The Rest of the ViewController should contain the UITabBar, But it is not showing. If i make the tabBar the rootController it will show the tabBar in the viewcontrollers. This would also make the firsttab the rootviewcontroller which it should not.
My question is then how can i make the loginview the rootViewController without an tabBar and still show the tabBar in the other viewcontrollers?
My code:
tabBarController = [[UITabBarController alloc] init];
MenuViewController *firstTab = [[MenuViewController alloc] initWithNibName:#"MenuViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:firstTab];
FixtureViewController *secondTab = [[FixtureViewController alloc] initWithNibName:#"FixtureViewController" bundle:nil];
UINavigationController *navController2 = [[UINavigationController alloc] initWithRootViewController:secondTab];
WorldCupViewController *thirdTab = [[WorldCupViewController alloc] initWithNibName:#"WorldCupViewController" bundle:nil];
UINavigationController *navController3 = [[UINavigationController alloc] initWithRootViewController:thirdTab];
LoginViewController *loginView = [[LoginViewController alloc] initWithNibName:#"LoginViewController" bundle:nil];
UINavigationController *navController4 = [[UINavigationController alloc] initWithRootViewController:loginView];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = #[navController, navController2, navController3];
navController.tabBarItem.image = [UIImage imageNamed:#"message-7"];
navController2.tabBarItem.image = [UIImage imageNamed:#"football-32"];
navController3.tabBarItem.image = [UIImage imageNamed:#"trophy-32"];
[[UITabBar appearance] setTintColor:[UIColor colorWithRed:110/255.0f green:89/255.0f blue:196/255.0f alpha:1.0f]];
[self.window setRootViewController:navController4];
[self.window makeKeyAndVisible];
What you need to do is transition the application from the LoginViewController to the Tabbar. What I would suggest doing is replacing the LoginViewController with the TabBar as the rootViewController.
Here is some sample code, perform this action in your AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
LoginViewController *loginView = [[LoginViewController alloc] initWithNibName:#"LoginViewController" bundle:nil];
UINavigationController *navController4 = [[UINavigationController alloc] initWithRootViewController:loginView];
[self.window setRootViewController:navController4];
[self.window makeKeyAndVisible];
return YES;
}
-(void)transitionToTabBar
{
// Set the TabBar how you are in your sample code, this is just an example.
[self.window setRootViewController:[[UITabBarController alloc] initWithNibName:#"SomeNib" bundle:Nil]];
[UIView transitionWithView:self.window duration:0.5f options:UIViewAnimationOptionTransitionCurlDown animations:^{
[self.window makeKeyAndVisible];
} completion:nil];
}
You should use main View controller (for MenuViewController) and by using segue you can present another view controller which has TabBar in it.
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;
}
I have tried to add a navigation controller to a tab bar controller but the tab appear black.
My code:
AppDelegate.m
#import "SettingsNavigationControllerViewController.h"
#import "SettingsViewController.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UIViewController *viewController1, *viewController2, *viewController3;
SettingsNavigationControllerViewController *viewController4;
UINavigationController *navigationController = [UINavigationController alloc];
viewController1 = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
viewController3 = [[ShareViewController alloc] initWithNibName:#"ShareViewController" bundle:nil];
SettingsViewController *settingViewController = [[SettingsViewController alloc] initWithNibName:#"SettingsViewController" bundle:nil];
viewController4 = [[SettingsNavigationControllerViewController alloc] initWithRootViewController:settingViewController];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = #[viewController1, viewController2, viewController3, navigationController];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
thank you in advance
This is because you added a navigationcontroller with no RootViewController and even doesnt initialized. Thats why the view appears as black. May be you mean to add viewController4 instead of navigationController . So change your code as below
self.tabBarController.viewControllers = #[viewController1, viewController2, viewController3, viewController4];
You need to first create the navigation controllers with rootviewcontrollers
viewController1 = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
UINavigationController *navigationController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
UINavigationController *navigationController2 = [[UINavigationController alloc] initWithRootViewController:viewController2];
Then instantiate the Tab Bar controller like this
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navigationController1, navigationController2, nil];
Create Navigation Controllers first.
UINavigationController *nav1 = [[UINavigationController alloc] init];
UIViewController *viewController1 = [[[FirstSteps alloc] initWithNibName:#"FirstView" bundle:nil] autorelease];
nav1.viewControllers = [NSArray arrayWithObjects:viewController1, nil];
UINavigationController *nav2 = [[UINavigationController alloc] init];
UIViewController *viewController2 = [[[Profiles alloc] initWithNibName:#"SecondView" bundle:nil] autorelease];
nav2.viewControllers = [NSArray arrayWithObjects:viewController2, nil];
Then initialize your tabbar controller like this.
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:nav1,nav2 ,nil];
self.window.rootViewController=self.tabBarController;
Hope this helps you.
Hey mate please visit the below link for tab bar example.
I think this is good and nice example which would be helpful to you.
https://github.com/alikaragoz/AKTabBarController
You only have to set your controllers name in appDelegate.m file
Here my code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
CSDisplayPlaza *displayPlaza = [[CSDisplayPlaza alloc] initWithNibName:#"CSDisplayPlaza" bundle:nil];
[displayPlaza setTabBarItem:[[UITabBarItem alloc] initWithTitle:#"one" image:[UIImage imageNamed:#"displayPlaza"] tag:0]];
UINavigationController *displayPlazaNav = [[UINavigationController alloc] initWithRootViewController:displayPlaza];
CSGameHall *gameHall = [[CSGameHall alloc] initWithNibName:#"CSGameHall" bundle:nil];
[gameHall setTabBarItem:[[UITabBarItem alloc] initWithTitle:#"two" image:[UIImage imageNamed:#"displayPlaza"] tag:1]];
UINavigationController *gameHallNav = [[UINavigationController alloc] initWithRootViewController:gameHall];
CSMyInformation *myInformation = [[CSMyInformation alloc] initWithNibName:#"CSMyInformation" bundle:nil];
[myInformation setTabBarItem:[[UITabBarItem alloc] initWithTitle:#"three" image:[UIImage imageNamed:#"myInformation"] tag:2]];
UINavigationController *myInformationNav = [[UINavigationController alloc] initWithRootViewController:myInformation];
self.tabBarController = [[UITabBarController alloc] init];
[tabBarController setViewControllers:[NSArray arrayWithObjects:displayPlazaNav,gameHallNav,myInformationNav,nil]];
[tabBarController setSelectedViewController:displayPlazaNav];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
In the simulator, cannot display any view controllers. Just a empty tabbar in my simulator. I don't know what happen.
My guess is displayPlaza is nil for some reason. Add log messages after you create every object to verify you in fact created one, and also the tab bar controllers array.
