尝试使用以下代码可能会对您有所帮助......

- (void)hideTabBar:(UITabBarController *) tabbarcontroller
{        
    for(UIView *view in tabbarcontroller.view.subviews)
    {
        if([view isKindOfClass:[UITabBar class]])
        {
            if([UIScreen mainScreen].bounds.size.height==568)
            {
                 [view setFrame:CGRectMake(view.frame.origin.x, 568 +20, view.frame.size.width, view.frame.size.height)];
            }
            else
            {
                 [view setFrame:CGRectMake(view.frame.origin.x, 480+20, view.frame.size.width, view.frame.size.height)];
            }

        }
        else
        {
            if([UIScreen mainScreen].bounds.size.height==568)
            {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 568)];
            }
            else
            {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)];
            }
        }
    }
}

- (void)showTabBar:(UITabBarController *) tabbarcontroller
{
    for(UIView *view in tabbarcontroller.view.subviews)
    {
        if([view isKindOfClass:[UITabBar class]])
        {
            if([UIScreen mainScreen].bounds.size.height==568)
            {
                [view setFrame:CGRectMake(view.frame.origin.x, 519, view.frame.size.width, view.frame.size.height)];
            }
            else
            {
                [view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)];
            }
        }
        else
        {
            if([UIScreen mainScreen].bounds.size.height==568)
            {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 519)];
            }
            else
            {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)];
            }
        }
    }
}

当您按下视图控制器时，只需使用  yourViewController.hidesBottomBarWhenPushed = YES;  [yourTabbarNavigationController pushViewController：helpViewController animated：YES];

这将删除黑色transculent图层，但如果您使用自定义tabbar，则还必须明确隐藏这些视图。
