Changing Tab bar programmatically

Question

I have created tabbar in storyboard .and i am trying to change default tab bar programmatically using following code.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Make sure your segue name in storyboard is the same as this line
    if ([[segue identifier] isEqualToString:@"TAB"])
    {
        UIStoryboard* storyboard   = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
        UITabBarController *tabBar = [storyboard instantiateViewControllerWithIdentifier:@"tabBar"];
        tabBar.selectedViewController = [tabBar.viewControllers objectAtIndex:1];
    }
}

But its not working.How i can do it? its not working at all.

Also i want to go back to home view controller when user select first tab.how we can achieve this functionality.

From the current selected view controller you can change tab selected index using code below.

[self.tabBarController setSelectedIndex:1];

To add Tab bar controller to viewcontrollers hirarchy IF YOU ARE USING NAVIGATION AS BASE then you can use:

UIStoryboard* storyboard   = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
        UITabBarController *tabBar = [storyboard instantiateViewControllerWithIdentifier:@"tabBar"];
        tabBar.selectedViewController = [tabBar.viewControllers objectAtIndex:1];

[self.navigationController pushViewController:tabBar animated:BOOL];
