        {
            NSLog(@"home");
            homeViewController *homeVc= [[homeViewController alloc] initWithNibName:@"homeViewController" bundle:nil];
            [self.view insertSubview:homeVc.view belowSubview:tabBar];
            break;
        }
        case 1:
        {

             NSLog(@"compus");
    compusViewController *compusVc= [[compusViewController alloc] initWithNibName:@"compusViewController" bundle:nil];
        [self.view insertSubview:compusVc.view belowSubview:tabBar];
            break;

        }

There is no direct methods to simple remove all subviews. You have to call removeFromSuperview for all subviews. Luckily, the code is concise. Use [self.containerView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]. – Sikhapol Saijit
