UITabBar is a top level view which means that almost all over views are underneath it. Even UINavigationController seats bellow tabBar.

You could hide tabBar like this:

- (void)hideTabBar:(UITabBarController *)tabbarcontroller withInterval:(NSTimeInterval)delay {
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:delay];
    for(UIView *view in tabbarcontroller.view.subviews)
    {
        if([view isKindOfClass:[UITabBar class]])
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y+50, view.frame.size.width, view.frame.size.height)];
        } 
        else 
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height+50)];
        }
    }
    [UIView commitAnimations];
}

And then show it back on like this:

- (void)showTabBar:(UITabBarController *)tabbarcontroller withInterval:(NSTimeInterval)delay {
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:delay];
    for(UIView *view in tabbarcontroller.view.subviews)
    {
        if([view isKindOfClass:[UITabBar class]])
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y-50, view.frame.size.width, view.frame.size.height)];
        } 
        else 
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height-50)];
        }
    }
    [UIView commitAnimations];
}

UITabBar is of height 50 px by default. So you just need to set new height to the frame and animate it.

You can add your view to the main window, and it will be over the tab bar:

[[myApp appDelegate].window addSubview:myView];
