Question

I have a view controller with a button and after clicking that button tabbarcontroller should appear.how to do it programatically.?

all the tutorials i found show tab bar immediately once the app is started.but i want it to be visible after the button is clicked and navigated to the other view.

i wrote code for navigating to a new page so that new page should consist of tab bar controller.

-(IBAction)buttonClicked
{

 ViewController *viewController = [[ViewController alloc]initWithNibName:@"view" bundle:nil];
        [self.navigationController pushViewController:viewController animated:YES];
        [viewController release];
}

Try something like this:

-(IBAction)buttonClicked
{
    UITabBarController *tabBarController = [[UITabBarController alloc] init];
    UIViewController *vc1 = [[UIViewController alloc] initWithNibName:@"VC1" bundle:nil];
    UITabBarItem *tbi1 = [[UITabBarItem alloc] initWithTitle:@"VC1" image:[UIImage imageNamed:@"vc1"] tag:1];
    vc1.tabBarItem = tbi1;
    // more viewControllers here

    tabBarController.viewControllers = [NSArray arrayWithObjects:vc1, vc2, vc3, nil];
    [self.navigationController pushViewController:tabBarController animated:YES];
}
