How do I integrate a UITabbarcontroller in a UIViewController class not in the app delegate? I was suppose to make a login view and after it the UITabBarController appears which was created in a UIViewController class? Can anyone suggest what needs to be done? thanks
You can still put the UITabBarController in the App Delegate, when the login is done, just tell the app delegate, and switch the them:
self.window.rootViewController=tabBarController;
if your Application is Navigation Based App, then Create TabBarController(with ViewControllers how many you want to add) and add it on Navigation Controller, like this
UITabBarController *tabBarController = [Utility configureMessagesTabBArController];
self.navigationController.navigationBarHidden=YES;
[self.navigationController pushViewController:tabBarController animated:YES];
[tabBarController release];
here is configureMessagesTabBArController Method from Utility class
+(UITabBarController *)configureMessagesTabBArController
{
UITabBarController *tabBarController = [[UITabBarController alloc]init];
AktuellesViewController *aktuelles_Controller = [[AktuellesViewController alloc]init];
TermineViewController *termine_Controller = [[TermineViewController alloc]init];
TopTenViewController *topTen_Controller = [[TopTenViewController alloc]init];
MediathekViewController *mediathek_Controller = [[MediathekViewController alloc]init];
KontaktViewController *kontakt_Controller = [[KontaktViewController alloc] init];
UINavigationController *nav1 = [[UINavigationController alloc]initWithRootViewController:aktuelles_Controller];
UINavigationController *nav2 = [[UINavigationController alloc]initWithRootViewController:termine_Controller];
UINavigationController *nav3 = [[UINavigationController alloc]initWithRootViewController:topTen_Controller];
UINavigationController *nav4 = [[UINavigationController alloc]initWithRootViewController:mediathek_Controller];
UINavigationController *nav5 = [[UINavigationController alloc]initWithRootViewController:kontakt_Controller];
nav1.navigationBar.tintColor = [UIColor blackColor];
nav2.navigationBar.tintColor = [UIColor blackColor];
nav3.navigationBar.tintColor = [UIColor blackColor];
nav4.navigationBar.tintColor = [UIColor blackColor];
nav5.navigationBar.tintColor = [UIColor blackColor];
[tabBarController setViewControllers:[[NSArray alloc]initWithObjects:nav1,nav2,nav3,nav4,nav5,nil]];
[nav1 release];
[nav2 release];
[nav3 release];
[nav4 release];
[nav5 release];
[aktuelles_Controller release];
[termine_Controller release];
[topTen_Controller release];
[mediathek_Controller release];
[kontakt_Controller release];
return tabBarController;
}

I want to create a tabBar in my app but only in a detailView not in the AppDelegate. I am searching how to do this in google but everything what I have figured out is in AppDelegate.m
I am trying to do something like this. This shows me a Tab bar with two buttons(without names) but I want to go from one FirstViewController with tabBar, to one of the two items SecondViewController or ThirdViewController with a navigationBar with one backItemButton for get back to the FirstViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[self setupTabBar];
}
- (void) setupTabBar {
tabBars = [[UITabBarController alloc] init];
NSMutableArray *localViewControllersArray = [[NSMutableArray alloc] initWithCapacity:4];
YPProfileViewController *profile = [[YPProfileViewController alloc] init];
YPProfileViewController *profile2 = [[YPProfileViewController alloc] init];
[localViewControllersArray addObject:profile];
[localViewControllersArray addObject:profile2];
tabBars.tabBarItem = profile2;
tabBars.viewControllers = localViewControllersArray;
tabBars.view.autoresizingMask==(UIViewAutoresizingFlexibleHeight);
[self.view addSubview:tabBars.view];
}
at least this works for me.
UIViewController *vc1 = [[UIViewController alloc] init];
vc1.title = #"FIRST";
vc1.view.backgroundColor = [UIColor blueColor];
UIViewController *vc2 = [[UIViewController alloc] init];
vc2.title = #"SECOND";
vc2.view.backgroundColor = [UIColor redColor];
UITabBarController *tabBar = [[UITabBarController alloc] init];
tabBar.viewControllers = #[vc1,vc2];
tabBar.selectedIndex = 1;
tabBar.view.frame = CGRectMake(50, 50, 220, 320);
[tabBar willMoveToParentViewController:self];
[self.view addSubview:tabBar.view];
[self addChildViewController:tabBar];
[tabBar didMoveToParentViewController:self];
In a UITabBarController, upon selecting a tab, I want that tab's UIViewController to change (assign a new viewcontroller). I'm trying this-
NSMutableArray *tabBarViewControllers = [myUITabBarController.viewControllers mutableCopy];
[tabbarViewControllers replaceObjectAtIndex:0 withObject:[[myViewcontroller1 alloc] init]];
[myUITabBarController setViewControllers:tabbarViewControllers];
But it gives error. How to assign a new UIViewController and refresh instantly?
This is based on femina's answer but doesn't require you to build the whole array of view controllers, it just lets you replace an existing view controller with another. In my case I wanted to swap in a different xib file for the iPhone 5 screen:
if ([[UIScreen mainScreen] bounds].size.height == 568) {
NSMutableArray *viewControllers = [NSMutableArray arrayWithArray:self.tabBarController.viewControllers];
Tracking *tracking568h = [[Tracking alloc] initWithNibName:#"Tracking-568h" bundle:nil];
tracking568h.title = [[viewControllers objectAtIndex:0] title];
tracking568h.tabBarItem = [[viewControllers objectAtIndex:0] tabBarItem];
[viewControllers replaceObjectAtIndex:0 withObject:tracking568h];
[tracking568h release];
[self.tabBarController setViewControllers:viewControllers animated:FALSE];
}
This changes the view controller for the first tab, keeping the same tab icon and label.
Please see this code , it offers 2 tabbar's with navigation.
In the AppDelegate.h please declare
UINavigationController *nav1;
UINavigationController *nav2;
UITabBarController *tab;
And in the Appdelegate.m , in the didFinishLaunchingWithOptions please add:-
tab = [[UITabBarController alloc]init];
ViewController *view1 = [[ViewController alloc]init];
nav1= [[UINavigationController alloc]initWithRootViewController:view1];
UITabBarItem *tab1 = [[UITabBarItem alloc]initWithTitle:#"Add" image:[UIImage imageNamed:#"Plus.png"] tag:1];
view1.title = #"Add";
[view1 setTabBarItem:tab1];
SettingsViewController *view2 = [[SettingsViewController alloc]init];
nav2= [[UINavigationController alloc]initWithRootViewController:view2];
UITabBarItem *tab2 = [[UITabBarItem alloc]initWithTitle:#"Setting" image:[UIImage imageNamed:#"settings.png"] tag:2];
view2.title = #"Setting";
[view2 setTabBarItem:tab2];
tab.viewControllers = [NSArray arrayWithObjects:nav1,nav2,nil];
self.window.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = tab;
Also check this link for further implementation ... Hope this helps :)
UItabBar changing View Controllers
In the AppDelegate.h

I am making an application which will have 3 pages
Login Page - first page after the app loads
My First Page- when user successfully logs in then he comes into this page.This page
contains a UITabBar with two UITabBarItems. The first one is connected to
My firstPage
and the other one to My Second Page.
My Second Page - this is another UIViewController.
I have made the login page but I am unable to find the solution to UITabBar adding in My First Page
Please help me out
Define
AppDelegate.h
#property (strong, nonatomic) UITabBarController *tabBarController;
in AppDelegate.m
didFinishLaunchingWithOptions
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.delegate=self;
self.tabBarController.selectedIndex=0;
self.tabBarController.delegate=self;
- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController{
return YES;
}
now when you get success login write below code in that method
AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
delegate.tabBarController = [[UITabBarController alloc] init];
delegate.tabBarController.selectedIndex = 0;
delegate.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];
delegate.tabBarController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self.navigationController pushViewController:delegate.tabBarController animated:YES];
Try this out,
suppose this is LoginViewController.m
-(IBAction)loginButtonClicked:(id)sender
{
[self createTabBarView];
}
//Create TabBar View here
-(void)createTabBarView
{
NSMutableArray *tabItems = [NSMutableArray array];
UIViewController *firstViewController = [[FirstViewController alloc] init];;
firstViewController = #"First View";
firstViewController = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemContacts tag:0];
[tabItems addObject:firstViewController];
UIViewController *secondViewController = [[SecondViewController alloc] init];;
secondViewController = #"Second View";
secondViewController = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemContacts tag:1];
[tabItems addObject:secondViewController];
self.tabBarController = [[UITabBarController alloc]init];
self.tabBarController.viewControllers = tabItems;
self.tabBarController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:tabBarController animated:YES];
}
Thanks,
Nikhil.
Are you using interface builder?
From my point of view, I'd rather like to use programmatic way to implement it.
//In the appDidFinishLaunch method
BOOL loggedIn = [[NSUserDefault standDefault]boolForKey:"userlogin"];
if(loggedIn)
{
//Setup your UITabbarViewController
}
else
{
//Setup your loginView Controller
}
After login in LogInViewController
- (void)didLogin
{
YourAppDelegate *delegate = [UIApplication shareApplication].delegate;
[delegate.window addSubView:self.tabBarViewController.view];
[delegate.window removeSubView:self.view]
//Other Config
}
You should create Tabbar at place where you can identify that login is successfully done. This method should be part of your loginViewController.
Create a function like below to create a Tabbar and present it over loginController.
-(void) createTabBarController
{
UITabBarController *tabBar = [[UITabBarController alloc]init];
UIViewController *firstViewController = [[[UIViewController alloc] init]autorelease];
UINavigationController *firstNavController = [[UINavigationController alloc]initWithRootViewController:firstViewController];
firstNavController.tabBarItem.title=#"First Controller";
firstNavController.tabBarItem.image = [UIImage imageNamed:#"first.png"];
UIViewController *secondViewController = [[[UIViewController alloc] init]autorelease];
UINavigationController *secondNavController = [[UINavigationController alloc]initWithRootViewController:secondViewController];
secondNavController.tabBarItem.title=#"First Controller";
secondNavController.tabBarItem.image = [UIImage imageNamed:#"first.png"];
[tabBar setViewControllers:[NSArray arrayWithObject:firstNavController,secondNavController,nil]];
[firstNavController release];
[secondNavController release];
[self presentModalViewController: tabBar];
[tabBar release];
}
Have a mainviewcontroller and on it have UIToolbar which has a UIBarButtonItem Info which shows UIViewcontroller modally.
Now when pressing Infobutton it is showing UIViewController modally which has UITextView but not showing UINavigationController with Done button.
I am not able to figure it out what i am missing in my code.
This is how i am showing UITextView and NavigationController in UIViewController modally.
#import "ModalViewController.h"
#import <QuartzCore/QuartzCore.h>
#implementation ModalViewController
#synthesize textView;
#synthesize navBar;
#synthesize navigationController;
#synthesize delegate;
-(void)dealloc
{
[textView release];
[navBar release];
[navigationController release];
[super dealloc];
}
- (void) viewDidLoad
{
[super viewDidLoad];
self.title = #"Info";
UINavigationController *navigationController = [[UINavigationController alloc]init];
//initWithRootViewController:viewController];
self.navigationController.navigationBar.tintColor = [UIColor brownColor];
self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(Done:)] autorelease];
self.textView = [[[UITextView alloc] initWithFrame:CGRectMake(0, 0, 320, 416)]autorelease];
self.textView.textColor = [UIColor whiteColor];
self.textView.font = [UIFont fontWithName:#"Georgia-BoldItalic" size:14];
//self.textView.delegate = self;
self.textView.backgroundColor = [UIColor brownColor];
self.textView.layer.borderWidth = 1;
self.textView.layer.borderColor = [[UIColor whiteColor] CGColor];
self.textView.layer.cornerRadius = 1;
self.textView.textAlignment = UITextAlignmentCenter;
self.textView.text = #"This is UITextView presenting modally.\nThis is UITextView presenting modally.\nThis is UITextView presenting modally.\nThis is UITextView presenting modally.\nThis is UITextView presenting modally.\nThis is UITextView presenting modally.
self.textView.editable = NO;
//[self.view addSubview:navigationController.view];
[self.view addSubview: self.textView];
//[navigationController release];
}
And this is how UIViewController presented modally
//Create a final modal view controller
UIButton *modalViewButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
[modalViewButton addTarget:self action:#selector(modalViewAction:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *modalBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:modalViewButton];
self.navigationItem.rightBarButtonItem = modalBarButtonItem;
- (void) modalViewAction:(id)sender
{
self.view = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]]autorelease];
//self.viewController = [[ModalViewController alloc] init];
[self.view setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
//ModalViewController *myModalViewController = [[ModalViewController alloc] init];
//UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:myModalViewController];
//navigationController.navigationBar.tintColor = [UIColor brownColor];
_viewController = [[ModalViewController alloc] init];
//[navigationController pushViewController:_viewController animated:YES];
[self presentModalViewController:self.viewController animated:YES];
//[self.view addSubview:navigationController.view];
//[navigationController release];
[myModalViewController release];
}
I will appreciate if you can figure out what i m doing wrong or missing in my code.
Thanks a lot.
This seems like a needlessly convoluted way of displaying the new controller. In my apps, I do it like this:
//this function displays (modally) view controller nested inside a navcontroller
- (void) showModalController
{
YourViewController * ecreator = [[YourViewController alloc] initWithNibName:#"YourViewController" bundle:nil];
UINavigationController * navcontrol = [[UINavigationController alloc] initWithRootViewController: ecreator];
[self presentModalViewController: navcontrol animated:YES];
[navcontrol release];
[ecreator release];
}
Now you want to do the graphical setup (navbar color etc) in the initWithNib and/or viewDidLoad functions of the YourViewController.
#synthesize navigationController;
so navigationController is your class member variable.
in the function
- (void) viewDidLoad
you declare a local variable
UINavigationController *navigationController
Please notice that the second navigationController is different from your member variable navigationController .
So, inside viewDidLoad you need to create object of your member variable navigationController. Not the local variable navigationController.
Do not RE-declare navigationController in viewDidLoad. Instead, create the object using member variable like:
navigationController = [[UINavigationController alloc]init];
Try this, it worked great for me. I had the exact same problem
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:#“segue_name"])
{
UINavigationController *nav = [segue destinationViewController];
ExampleViewController *exampleVC = (ExampleViewController *) nav.topViewController;
//Setup any properties here and segue
}
}
my app is based on tabbar controller
now in my default view i am showing a viewController and lets say it has Button A, when user press A it should load a my tableviewController but nothing is happening??
-(IBAction)promo:(id)sender
{
aRoot= [[tableViewController alloc] initWithNibName:#"tableViewController" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:aRoot animated:YES];
}
but its not loading anything no error even???
/////////// UPDATE
i did this
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
Promo *aPromo = [[Promo alloc] initWithNibName:nil bundle:nil];//button A is deifned on this VC
// then...
aNav = [[UINavigationController alloc] initWithRootViewController:aPromo];
// [pageOne release];
and in promoviewController
-(IBAction)promo:(id)sender
{atab= [[TableViewController alloc] initWithNibName:#"TableViewController" bundle:nil];
//TableViewController *atab1 = [[TableViewController alloc]initWithNibName:#"TableViewController" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:atab animated:YES];
}
You need a navigationController to push a viewController.
you can't add a viewcontroller to a uitabbar if you want to use the navigation controller.
Where you make your tab bar controller you have to do this:
MyFirstTabViewController *pageOne = [[MyFirstTabeViewController alloc] initWithNibName:nil bundle:nil];
// then...
UINavigationController *ncOne = [[UINavigationController alloc] initWithRootViewController:pageOne];
[pageOne release];
then add ncOne to the tab bar instead of the view controller. :) Then your code in the question should work (given that you're properly declaring aRoot in the header).
EDIT
Start again... choose a view based application call it TabBarTest.
Right click on classes and add three new classes. They need to be subclasses of UIViewController or UITableViewController. Lets say they're called RootViewOne RootViewTwo and SecondaryViewController.
Then open TabBarTestViewController.m
Uncomment the viewDidLoad method.
You need to now put this code in that method:
UITabBarController *tbc = [[UITabBarController alloc] init];
NSMutableArray *viewControllers = [NSMutableArray array];
RootViewOne *vc1 = [[RootViewOne alloc] initWithNibName:nil bundle:nil];
UINavigationController *nc1 = [[UINavigationController alloc] initWithRootViewController:vc1];
nc1.view.backgroundColor = [UIColor redColor];
[viewControllers addObject:nc1];
[vc1 release];
RootViewTwo *vc2 = [[RootViewTwo alloc] initWithNibName:nil bundle:nil];
UINavigationController *nc2 = [[UINavigationController alloc] initWithRootViewController:vc2];
nc2.view.backgroundColor = [UIColor blueColor];
[viewControllers addObject:nc2];
[vc2 release];
[tbc setViewControllers:viewControllers animated:YES];
[self presentModalViewController:tbc animated:YES];
Now open RootViewOne.m and in viewDidLoad put this:
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setTitle:#"Click to move through stack" forState:UIControlStateNormal];
[button addTarget:self action:#selector(moveToNextView:) forEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
Now you're going to need a custom method:
-(void)moveToNextView:(id)selector {
SecondaryViewController *page = [[SecondaryViewController alloc] initWithNibName:nil bundle:nil];
page.title = #"Next Page";
page.view.backgroundColor = [UIColor greenColor];
[self.navigationController pushViewController:page animated:YES];
[page release];
}
This is only basic, but you should get an understanding of the kinad process you need to go through. I typed this straight into the browser so there may be spelling mistakes... watch out if you get any errors or warnings. Hopefully this can help you with your project.
Finally i solved this , i changed that VC to Navigation view Controller and then i can push the new view based on button tap,, thanks to thomas also who helped me a lot but i couldn't figure it out.
