Answer 1

If You Hide tabBar then how can you navigate to tab 2nd and 3rd.
I suggest to add welcomeView and after welcomeView add tabBar.

Or you can use this code

[self hideTabBar:self.tabBarController];


- (void) hideTabBar:(UITabBarController *) tabbarcontroller {

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    for(UIView *view in tabbarcontroller.view.subviews)
    {
        if([view isKindOfClass:[UITabBar class]])
        {
            [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];
        } 
        else 
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)];
        }

    }
    [UIView commitAnimations];    
}

[self  showTabBar:self.tabBarController];  

- (void) showTabBar:(UITabBarController *) tabbarcontroller {

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:0.5];
        for(UIView *view in tabbarcontroller.view.subviews)
        {
            NSLog(@"%@", view);

            if([view isKindOfClass:[UITabBar class]])
            {
                [view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)];

            } 
            else 
            {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)];
            }


        }

        [UIView commitAnimations]; 
    }
