Adding UITabBarController to a UIViewController

My app currently has a UINavigationController and I'd like to push a UITabBarController at some point when a button is clicked. I am trying to create it on Interface Builder (as opposed to programatically).

All online tutorials show how to create a tab bar based app, which involves dragging a UITabBarController into the MainWindow.xib which is obviously not what I want.

What I did was create a UIViewController, and its nib file, dragged a UITabBarController. Now pushing that UIViewController to the navigation controller will show an empty view (its empty view). Removing the view in the view controller will crash the app. How can I tell the UIViewController to load a UITabBarController instead of its own view?

For those down-voting me: it would be decent to at least provide a comment. The question is not a poor question. The questions is asking for suggestions for how to use a UITabBarController in an unorthodox way. I tried most of the suggestions and they do not work. If you are down-voting, at least write a comment.

take a uiview of tab bar controller means create an interface builder with tabs and add that tab bar uivew in your classes where ever u wanted the tab bar

for example take a tab bar uiview of 3 tabs in that uiview take the three buttons in the interface builder

for every navigation of that classu should add this uiview class

-(IBAction)firt_button_pressed:(id)sender
{

}

-(IBAction)second_button_pressed:(id)sender
{

}

The problem was, as I believe I've mentioned somewhere, is that the XIB does not have a UIView connected to it. When the UIView is deleted in a XIB file and a UITabBarController is added, the view property of the XIB has to be connected to the UITabBarController's view. I connected it and it worked. That was the reason why I was getting a SIGTRAP.

I remember doing something similar to this...

I had to create a custom UITableViewController to do this, if you are going to use UINavigationController to 'push' to it.

Doing it only in interface builder may be a bit tricky, it's been a while since I've been at it, I do recall it was a bit of a nightmare to get going correctly.

You can see this this may help you

Since this is how you want your app to be: - Navigation Controller - Root View Controller - Other View Controllers - Tab Bar Controller - First VC under tab - Second VC under tab - Third VC under tab - more view controllers

in your view controller where you want to pushViewController to UITabBarController use this

//create a UITabBarController object
UITabBarController *tabBarController=[[UITabBarController alloc]init];

//FirstViewController and SecondViewController are the view controllers you want on your UITabBarController (Number of view controllers can be according to your need)
FirstViewController *firstViewController=[[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
SecondViewController *secondViewController=[[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];

//adding view controllers to your tabBarController bundling them in an array
tabBarController.viewControllers=[NSArray arrayWithObjects:firstViewController,secondViewController, nil];

//navigating to the UITabBarController that you created
[self.navigationController pushViewController:tabBarController animated:YES];

In YourView controller make IBOutlet of tabBarController

in .h file 

#import <UIKit/UIKit.h>

@interface YourView : UIViewController
{
    IBOutlet UITabBarController *tabBarController;
}
-(IBAction)loadTabBar:(id)sender;
@end

and in .m file 

#import "YourView.h"
#import "FirstViewController.h"
#import "SecondViewController.h"

@implementation YourView

-(IBAction)loadTabBar:(id)sender
{
    FirstViewController *firstView = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];
    SecondViewController *secondView = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
    tabBarController = [[UITabBarController alloc] init];
    tabBarController.viewControllers = [NSArray arrayWithObjects:firstView, secondView, nil];
    [self.navigationController pushViewController:tabBarController animated:YES];
}
@end

The tabBarController IBOutlet must be connected to the UITabBarController that on the .xib file. And that UITabBarController with two view controllers named FirstViewController, SecondViewController.

Hi just make both nav controller and tabBar Controller in app delegate. Initially add navController to your root view..

[self.window addSubview:navigationController.view];

and whenever you want to add tab bar then remove navController and add tabBarController.

-(void)addTabBarController
{
    AppDelegate *appdelegte =(AppDelegate*)[[UIApplication sharedApplication]delegate];

    [[[appdelegte navigationController] view]removeFromSuperview];

    [[appdelegte window]addSubview:[[appdelegte tabcontroller]view]];

    [[appdelegte tabcontroller]setSelectedIndex:0];
}

If you get any problem then ask me again..
