Im trying to use the MHTabBarController https://github.com/hollance/MHTabBarController
, in the example the custom view controller is added as a rootViewController in app delegate,
i want to add 3 tabs inside a standard tab bar controller's view for example MainViewController
here is my code inside viewDidLoad in MainViewController.m:
//MHTabBarController config
ListViewController *listViewController1 = [[ListViewController alloc] initWithStyle:UITableViewStylePlain];
ListViewController *listViewController2 = [[ListViewController alloc] initWithStyle:UITableViewStylePlain];
ListViewController *listViewController3 = [[ListViewController alloc] initWithStyle:UITableViewStylePlain];
listViewController1.title = #"Tab 1";
listViewController2.title = #"Tab 2";
listViewController3.title = #"Tab 3";
NSArray *viewControllers = #[listViewController1, listViewController2, listViewController3];
MHTabBarController *tabBarController = [[MHTabBarController alloc] init];
tabBarController.delegate = self;
tabBarController.viewControllers = viewControllers;
[self.view addSubview:tabBarController.view];
ive also added the in MainViewController.h
but its not working, its showing a table but not the tabs on top.
what im missing?
That code should go inside the AppDelegate.m
Something like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
MainViewController *mainViewController = [[MainViewController alloc] init];
mainViewController.title = #"Main Tab";
NSArray *viewControllers = #[mainViewController];
MHTabBarController *tabBarController = [[MHTabBarController alloc] init];
tabBarController.delegate = self;
tabBarController.viewControllers = viewControllers;
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
This way you're adding a the tab bar into the MainViewController, if you wanna add the same tab bar into other view controllers, just add the view controllers into the viewControllers array.

I created tab bar and side menu using Sw reveal programmatically but after implementing all process i cant able to view side menu and my tab bar also disappeared...i don't know how to alloc them pleas help me out
#implementation AppDelegate
#synthesize window = _window;
#synthesize viewController = _viewController;

// Override point for customization after application launch.
self.tabBarController =[[UITabBarController alloc]init];

mainRevealController.delegate = self;
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
You set your window.rootViewController two times. And it seems the second time you assign nil to it, as I can't see any initialization/assignement to self.viewController.
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 a project with navigationController and storyboard.
Now i need to add another project to this (combine two projects)
I want to use TabbarController to switch between two navigationControllers.
How can I realise this?
put Down this Code in Your AppDelegates view controller :-
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UITabBarController *tabBar = [[UITabBarController alloc] init];
ViewController *homeVC = [[ViewController alloc] init];
homeVC.tabBarItem.title = #"Home";
homeVC.tabBarItem.image = [UIImage imageNamed:#"Home-icon.png"];
UINavigationController *HomeNavi = [[UINavigationController alloc] initWithRootViewController:homeVC];
settingViewController *settingVC = [[settingViewController alloc] init];
settingVC.tabBarItem.title = #"Setting";
settingVC.tabBarItem.image = [UIImage imageNamed:#"Setting-icon.png"];
UINavigationController *settingNavi = [[UINavigationController alloc] initWithRootViewController:settingVC];
tabBar.viewControllers = [NSArray arrayWithObjects:HomeNavi,settingNavi, nil];
HomeNavi.navigationBarHidden = YES;
settingNavi.navigationBarHidden = YES;
[self.window makeKeyAndVisible];
self.window.rootViewController = tabBar;
// Override point for customization after application launch.
return YES;
}
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.
How to insert UINavigationController inside UITabBarController.
Currently I have main UITabBarController with declatarion inside application delegate like this (so tab is main)
self.window.rootViewController = self.tabBarController;
And inside one of tabs I want to insert UINavigationController, and can't get it.
The code is contructed like this:
MainWindow.xib with UITabBarController object with tab typed as UINavigationController (point to NavigationHistory.xib) - screenshot: invalid link
NavigationHistory.xib contains only UINavigationController where view point to History.xib
History.xib have only UITableView element - screenshot: invalid link
And now UIViewController doesn't display my View1 view, and I have no clue why it may be. Maybe you have any clue? or point me to the place where such configuration is done.
I'll answer myself. It's good explained at

Write a code in appdelegate.m file.....
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
NSMutableArray *Mutablearray = [[NSMutableArray alloc] init];
UIViewController *1st_View = [[FirstViewController alloc] initWithNibName:#"FirstViewController_iPhone" bundle:nil];
UINavigationController *Navigation = [[UINavigationController alloc] initWithRootViewController:1st_View];
[Mutablarray addObject:Navigation];
UIViewController *2nd_View = [[SecondViewController alloc] initWithNibName:#"SecondViewController_iPhone" bundle:nil];
UINavigationController *Navigation = [[UINavigationController alloc] initWithRootViewController:2nd_View];
[Mutablearray addObject:Navigation];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = Mutablearray;
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
Add your controller object to UINavigationController, and add that navigationcontroller object to UITabBarController
UINavigationController is a subclass of UIViewController, a UITabBarController expects an array of UIViewControllers (and therefore UINavigationController ); this tells me me that I can give a UITabBarController an array of UINavigationControllers (or sublasses thereof) giving the desired interaction.
