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 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 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.

You only have to set your controllers name in appDelegate.m file
I want to Push my viewController on PresentViewController
When i click on button initially i am loading PresentViewController, here is my code.
- (IBAction)JoinClicked:(id)sender{
JoinWithViewController *detail_view_controller = [[JoinWithViewController alloc] initWithNibName:#"JoinWithViewController" bundle:nil];
[self.view.window.rootViewController presentViewController:detail_view_controller
animated:YES
completion:NULL];
}
this works fine, but when i click on button which is there on PresentViewController on click i want to Push my view, but in does not pushes.
Please help, Thanks in advance.
JoinWithViewController *detail_view_controller = [[JoinWithViewController alloc] initWithNibName:#"JoinWithViewController" bundle:nil];
[self.navigationController pushViewController:detail_view_controller animated:YES];
Try like this to push viewController. If you use TabBar do like this in AppDelegate. If you create TabBar Drag and drop means leave that. Create TabBar Programatically like below.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UITabBarController *tabController = [[UITabBarController alloc]init];
self.viewController = [[CalculatorViewController alloc] initWithNibName:#"CalculatorViewController" bundle:nil];
UITabBarItem *tab_item1 = [[UITabBarItem alloc]init];
//tab_item1.title = #"Calculator";
tab_item1.image = [UIImage imageNamed:#"Calculator.png"];
[self.viewController setTabBarItem:tab_item1];
UINavigationController *nav1 = [[UINavigationController alloc]initWithRootViewController:self.viewController];
ShowPhoneViewController *phone = [[ShowPhoneViewController alloc]init];
UITabBarItem *tab_item2 = [[UITabBarItem alloc]init];
tab_item2.title = #"Latest Mobiles";
tab_item2.image = [UIImage imageNamed:#"Mobile.png"];
[phone setTabBarItem:tab_item2];
UINavigationController *nav2 = [[UINavigationController alloc]initWithRootViewController:phone];
CurrencyConvertorViewController *currency = [[CurrencyConvertorViewController alloc]init];
UITabBarItem *tab_item3 = [[UITabBarItem alloc]init];
tab_item3.title = #"Units Convertor";
tab_item3.image = [UIImage imageNamed:#"Dollar.png"];
[currency setTabBarItem:tab_item3];
UINavigationController *nav3 = [[UINavigationController alloc]initWithRootViewController:currency];
SettingsPageViewController *setting = [[SettingsPageViewController alloc]init];
UITabBarItem *tab_item4 = [[UITabBarItem alloc]init];
tab_item4.title = #"Settings";
tab_item4.image = [UIImage imageNamed:#"Settings.png"];
[setting setTabBarItem:tab_item4];
UINavigationController *nav4 = [[UINavigationController alloc]initWithRootViewController:setting];
tabController.viewControllers = [NSArray arrayWithObjects:nav1, nav2, nav3, nav4, nil];
self.window.rootViewController = tabController;
[self.window makeKeyAndVisible];
return YES;
}
I hope you got now
pushviewcontroller is the feature of UINavigationController where you can push one viewcontroller on another vierw controller. Here you are using a single viewcontroller as a rootviewcontroller so either you must change your rootviewcontroller to UINavigationcontroller or you can use "addSubview method" to add new viewController on the current viewcontroller.
but the better option is to add uinavigationcontroller as a rootviewcontroller.
AppDelegate.m
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
FirstViewController *first = [[FirstViewController alloc]
initWithNibName:#"FirstViewController" bundle:nil];
UINavigationController *navController =[[UINavigationController alloc]
initWithRootViewController:first];
[self.window setRootViewController:navController];
}
Now when as you want to switch from FirstViewController to SecondViewController on button clicked than you have to use pushviewcontroller
FirstViewController.h
-(void) nextBtnPressed {
SecondViewController *second = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
[self.navigationController pushViewController:second animated:TRUE];
}
I am making an application but I'm still a beginner and I'm trying to get used to the RootViewController and how it should be set.
At the beginning my application launches, I want there to be a View which is not in my tabBarController (which is set to be my rootViewController).
What I am trying to ask is, Can I have another view which is outside my UITabBarController launch first without it being in the tabBarController's items list?

I know you already selected an answer but all that's doing is pushing a UITabBar view on top of an existing view, not creating a new UITabBarController view. Based on our brief conversation (latest XCode, no StoryBoards, using XIBs) you're going to want to create a xib as a UITabBarController then push it into view...
View *view = [[View alloc] initWithNibName:#"myUITabBarXIB" bundle:nil];
view.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController: view animated:YES];
This will present your XIB file but not on top of the existing view controller when the desired action takes place.
yes! ofcourse you do.
[self.view addsubview:yourTabbar.view];
Hope this will help you.
I'm trying to add a UINavigationController to my existing view controller by adding this in ViewDidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
navController = [[UINavigationController alloc]init];
[self.view addSubview:navController.view];
}
But by doing it this way, it completely blocks my view. It puts a UINavigationBar on the top but the rest of the view doesn't respond to input.
This is how I am presenting the view. The SecondViewController is the one I want to have a NavController:
UITabBarController *tabController = [[UITabBarController alloc] init];
FirstViewController *viewController1 = [[FirstViewController alloc] initWithNibName:#"CardsViewController" bundle:nil];
UITabBarItem *tab1 = [[UITabBarItem alloc] initWithTitle:#"First"
image:[UIImage imageNamed:#"img1.png"] tag:1];
[viewController1 setTabBarItem:tab1];
SecondViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"ShoppingViewController" bundle:nil];
UINavigationController *SecondViewNavCont = [[UINavigationController alloc]initWithRootViewController:viewController2];
UITabBarItem *tab2 = [[UITabBarItem alloc] initWithTitle:#"Second"
image:[UIImage imageNamed:#"img2.png"] tag:2];
[SecondViewNavCont setTabBarItem:tab2];
UIViewController *viewController3 = [[UIViewController alloc] init];
UITabBarItem *tab3 = [[UITabBarItem alloc] initWithTitle:#"Third"
image:[UIImage imageNamed:#"img3.png"] tag:3];
[viewController3 setTabBarItem:tab3];
tabController.viewControllers = [NSArray arrayWithObjects:viewController1,
viewController2,
viewController3,
nil];
[self.view addSubview:tabController.view];
You cannot add it to the current view controller
What you need to do is instead of presenting the ViewController is to add this viewcontroller to the navigationview controller and present that
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:YourPresentedViewController];
//then present the navController
[self presentModalViewController:navController animated:YES];
Now when you present it do the following
NSArray arrayWithObjects:viewController1,
SecondViewNavCont,
viewController3,
nil];
You can try this code for load uiviewcontroller to uinavigationcontroller:
yourviewController *viewcontroller=[[yourviewController alloc] initWithNibName:#"yourviewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewcontroller];
[self presentModalViewController:navController animated:YES];
(or) you want to load uinavigationcontroller in application startup try below code in your application delegate class:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewcontroller.view];
[self.window addSubview:navController.view];
[self.window makeKeyAndVisible];
return YES;
}
Welcome!
You need to set the RootViewController for the navController object. Then further you can push UIViewcontroller objects using pushViewController method.
You need to add a view for that Navigation Controller. The added Navigation Controller has no view so it was overlaying on the UIViewController
You need to add
[[UINavigationController alloc] initWithNibName:#"ViewControllerName" bundle:nil];
