Answer 1

Use the code below to hide/show tab bar controller in animated style.
hiddenTabBar is a BOOL variable.

- (void) hidetabbar {

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.0];

    for(UIView *view in objtabbar.view.subviews)
    {

        if([view isKindOfClass:[UITabBar class]])
        {

            if (hiddenTabBar) {
                [view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)];
            } else {
                [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];
            }
        } else {
            if (hiddenTabBar) {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)];
            } else {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)];
            }

        }
    }

    [UIView commitAnimations];

    hiddenTabBar = !hiddenTabBar;
}
