Adding tab bar controller to the UIView by [self.view addSubview:tabBarController.view];
is not loaded the content view controllers view, while selecting the tab bar items it crashed. When set the tab bar controller to the root view controller its working fine. How to set tab bar controller into UIView so that I can set another view for some other purpose like iAd?
You just create one tabbar controller in app delegate but don't add it to window, and in view controller you have just add these:
gObjAppDelegate.tabBarController = [[UITabBarController alloc] init];
gObjAppDelegate.tabBarController.viewControllers = #[viewController1, viewController2];
[gObjAppDelegate.tabBarController setSelectedIndex:0];
[self.navigationController pushViewController:gObjAppDelegate.tabBarController animated:YES];
gObjAppDelegate is shared singleton instance of app delegate.This way it worked for me.

The root View View controller is Navigation controller and its first level is a TabViewController.One of the tab item is a TableViewController.
Here is the relationship:
However the navigation bar overlap the table view:
I have also set simulated metrics,So what can be the problem??
Thanks for any help.
Simulated metrics are just that, simulated. They do not actually apply to the compiled product.
To fix this, I find it easiest to set the edgesforextendedlayout with the various values of edge values. Usually all but the top.
The rootViewController should be the UITabBarController. Follow this code:
1.Make the UITabBarController the rootViewController in the application delegate or in your main.storyboard set it as the initial View Controller.
2.In the UITabBarController.m place this code there to create the UINavigationController with a UIViewController embeded inside of it.
//Inside UITabBarController.m
- (void)viewDidLoad {
[super viewDidLoad];
UIViewController *vc = [[UIViewController alloc]init];
UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:vc];
self.viewControllers = #[navCon];
}
Get rid of the navigation controller in the beginning and, instead, embed the tableviewcontroller inside a navigation controller.
(Select the view controller -- Click "editor" > "embed in" > "navigation controller").
Make sure the tab bar controller is the root view controller as well
This will also fix the overlapping issue
I have a tab bar controller with a button like so:
- (void) addButtonPressed:(UIButton *) sender
{
[sender setBackgroundColor:[UIColor regularColor]];
PostViewController *post = [[PostViewController alloc] init];
[self.navigationController pushViewController:post animated:YES];
}
This code runs but the PostViewController is never shown and the tab bar controller remains.
How do I get to push to a new controller?
The NavigationController was created and StartViewController was add as rootController.
Then in StartViewController I have:
TabBarController *tab = [[TabBarController alloc] init];
// Presentation
[self presentViewController:tab animated:NO completion:nil];
in tab bar you need to create separate Navigation Controllers.
Suppose there are 3 tabs A, B and C. All the three tabs have functionality of navigation from one view to another. than you need to create three separate Navigation controllers eact pointing to Tab A, B and C. In this way you can navigate to any class within the specific Tab.
Check out this link for more details.
Hope this will help you. Happy coding :)
You may need to embed your tab bar controller within a navigation controller, In your storyboard click on your tabbarController so that it is highlighted with all the blue lines and then go to Editor in Xcode choose embed IN> UINavigationController ..If you want to do it programatically then in your AppDelegate where you setup your Window just Use This::
UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController:tabBarController];
navigationController.toolbarHidden=YES;
navigationController.navigationBarHidden=YES;
self.window.rootViewController =navigationController;
if you are using .xib then you have to use NSBundle to load nib
if you are using storyboard then you need to use prepareForSegue to pass on data or just display it out
I am working on an app in which I have to display multiple view controllers side by side (split views). For this purpose I have added views as child view controller.
OBJECTIVE: I want to show navigation bar on one child view controller along with already shown separate navigation bar on parent view controller.
PROBLEM: Navigation bar doesn't get shown on child view controller.
EDIT: I have also set navigation bar of parent view controller as hidden but when child view controller get's called, the navigation bar gets appeared on parent view controller, not on child view controller.
Code to add child view controller is:
MyChildViewController *childViewController = [[MyChildViewController alloc] initWithNibName:#"MyChildViewController" bundle:nil];
[self addChildViewController:childViewController];
[childViewController.view setFrame:CGRectMake(0.0f, 0.0f, self.rightContainerView.frame.size.width, self.rightContainerView.frame.size.height)];
[self.rightContainerView addSubview:childViewController.view];
[childViewController didMoveToParentViewController:self];
This code is working fine and child view controller gets add perfectly. I want to know is it possible or not?
Thanks in advance.
I solved this problem by myself through following way:
MyChildViewController *childViewController = [[MyChildViewController alloc] initWithNibName:#"MyChildViewController" bundle:nil];
[childViewController.view setFrame:CGRectMake(0.0f, 0.0f, self.rightContainerView.frame.size.width, self.rightContainerView.frame.size.height)];
UINavigationController *childNavController = [[UINavigationController alloc] initWithRootViewController:childViewController];
childNavController.view.frame = childViewController.view.frame;
[self addChildViewController:childNavController];
[self.rightContainerView addSubview:childNavController.view];
[childNavController didMoveToParentViewController:self];
Now when I add navigation bar in MyChildViewController, it gets added in child view controller and does not affect navigation bar of parent view controller. The navigationController property of child view controller is also different than navigationController property of parent view controller and both have their own navigation stacks.
add Navigation bar like this
It will be appear in your all view controller
Another way to do:
Put this code into didFinishLaunchingWithOptions method in appdelegate.m file.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
ECViewController * ec = [[ECViewController alloc] initWithNibName:#"ECViewController" bundle:nil];
UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController:ec];
self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];
return YES;
Add a Nib file(ECViewController) by simply following these steps:
1: Right click in project root
2: Add new file
3: Go to user interface.
4: Select view
5: Give it name same as your view controller name i gave ECViewController in my case.
Click on newly created nib file
Click on file owner fist yellow box on left side. make an connection with view by simple dragging with control keyword.click on view when popup appear.
Now goto identity inspector (fourth section from staring in left side).
Write your class name in Class name textBox appeared.
By this you can able to open an xib in iOS7 if you don't want to use storyboard.
Now if you need view controller with navigation controller.
Then open your view controller by this way.
ECViewController1 *v = [[ECViewController1 alloc]initWithNibName:#"ECViewController1" bundle:nil];
[self.navigationController pushViewController:v animated:YES];
Its too late for this edited answer, Hope it will help someone other.
Set the y position of child view correctly.
MyChildViewController *childViewController = [[MyChildViewController alloc] initWithNibName:#"MyChildViewController" bundle:nil];
[self addChildViewController:childViewController];
[childViewController.view setFrame:CGRectMake(0.0f, 44.0f, self.rightContainerView.frame.size.width, self.rightContainerView.frame.size.height)];
[self.rightContainerView addSubview:childViewController.view];
[childViewController didMoveToParentViewController:self];
I have found the link from stackoverflow we need to add navigation bar manually there is no alternate for this.
I am a beginner in programming in iOS. I have a iOS application that has two classes(with xib), firstviewcontroller and secondviewcontroller. I want to add a tab bar to switch between these view controllers. if I for example add a tab bar to the first view, how to connect the views to the tab bar? Its just there, doing nothing..
Try Look into this url , this will help.

This assumes that you want the tab bar as the main interface of your app.
In your app delegate, create a subclass of UITabBarController:
UITabBarController *myTbc = [UITabBarController alloc] init];
Create instances of your two view controllers and add them to an NSArray
NSArray *tabsArray = #[firstVC, secondVC];
Set that NSArray as the viewControllers property of the tab bar controller
[myTbc setViewControllers:tabsArray];
Set the tab bar controller as the app's root view:
self.window.rootViewController = theTbc;
Design requirement:
Show a list of items the user can pick from
After having picked an item, bring the user to a new view with a back button. The new view should contain a list of tabs at the bottom that are not present in the first screen
When clicking an item in the tabs, a new screen should appear with a back button and the tabs should still be visible at the bottom.
Clicking a tab should take the user back up the hierarchy to #2. Not to the first screen.
I have tried following structure:
UINavigationController
UIViewController with a UITableView
UIViewController with a UITabBar (like here http://www.wiredbob.com/2009/04/iphone-tweetie-style-navigation.html)
and also
UINavigationController
UIViewController with a UITableView
UITabbarController
Both cases work fine with displaying the UITabBar, but when I click an item in one of the tabs and push a new UIViewController, then the tabs at the bottom disappears. I want the tabs to remain in place for all pushed UIViewControllers that occurs inside a tab of the UITabBarController.
A related question is this one but it doesn't deal with the problem of pushed viewcontrollers inside a tab:
Tab bar controller inside a navigation controller, or sharing a navigation root view
Do I need to change the rootcontroller to the UITabController? Anyone actually implemented this?
Here is the correct structure:
UITabBarcontroller (UIWindow's rootViewController)
->UINavigationController (first tab)
-->UIViewController
->UINavigationController (second tab)
-->UIViewController
It sounds like you want to change the layout of your view hierarchy to accommodate your requirements. You should present your view controllers as such:
UITabBarController -> UINavigationController -> UIViewController
In your app delegate, you can implement this programmatically using something along the lines of:
UIViewController *viewControllerOne = [[[UIViewController alloc] init] autorelease];
UINavigationController *navigationControllerOne = [[[UINavigationController alloc] initWithRootViewController:viewControllerOne] autorelease];
UIViewController *viewControllerTwo = [[[UIViewController alloc] init] autorelease];
UINavigationController *navigationControllerTwo = [[[UINavigationController alloc] initWithRootViewController:viewControllerTwo] autorelease];
UITabBarController *tabBarController = [[[UITabBarController alloc] init] autorelease];
[tabBarController setViewControllers:[NSArray arrayWithObjects:navigationControllerOne, navigationControllerTwo, nil]];
[[self window] setRootViewController:tabBarController]
I haven't checked the above, it's just written from memory but should do what you require as an example.
Using this format, you can push any additional view controllers on to the navigation controller stack without your tab bar disappearing.
If you want to push this view hierarchy without having the tab bar controller as your root view controller, simply push the tab bar controller instead of setting it as the root view controller in the app delegate.
Hope that helps!
