how to remove background view

Question

I am using UITabBarController on a view controller i.e launchviewcontroller which contains code on loadview as below:

- (void)loadView
{
   viewControllers=[[NSMutableArray alloc]initWithCapacity:2];
    tabBarController=[[UITabBarController alloc]init];  
   MyProfileViewController *view1=[[MyProfileViewController alloc]init];
   localNavigationController=[[UINavigationController alloc]initWithRootViewController:view1];
   localNavigationController.navigationBar.alpha=1.0;
   //   localNavigationController.navigationBar.tintColor=[UIColor colorWithRed:0.65 green:0.84 blue:0.88 alpha:1];
   localNavigationController.navigationBar.tintColor=[UIColor blackColor];

   //    localNavigationController.navigationBar.
   [viewControllers addObject:localNavigationController];
   [view1 release];
   [localNavigationController release];
   localNavigationController=nil;


   TodaysPicksViewController *view2=[[TodaysPicksViewController alloc]initWithLeagueType:@"CFL Football"];
   localNavigationController=[[UINavigationController alloc]initWithRootViewController:view2];
   localNavigationController.navigationBar.alpha=1.0;
   localNavigationController.navigationBar.tintColor=[UIColor blackColor];
   [viewControllers addObject:localNavigationController];
   [view2 release];
   [localNavigationController release];
   localNavigationController=nil;


   Rules_PoliciesViewController *view3=[[Rules_PoliciesViewController alloc]init];
   localNavigationController=[[UINavigationController alloc]initWithRootViewController:view3];
   localNavigationController.navigationBar.alpha=1.0;
   localNavigationController.navigationBar.tintColor=[UIColor blackColor];
   [viewControllers addObject:localNavigationController];
   [view3 release];
   [localNavigationController release];
   localNavigationController=nil;

    LogoutViewController *view4=[[LogoutViewController alloc]init];
   localNavigationController=[[UINavigationController alloc]initWithRootViewController:view4];
   localNavigationController.navigationBar.alpha=1.0;
   localNavigationController.navigationBar.tintColor=[UIColor blackColor];
   [viewControllers addObject:localNavigationController];
   [view4 release];
   [localNavigationController release];
   localNavigationController=nil;

   appDel=[[UIApplication sharedApplication]delegate];

   tabBarController.viewControllers=viewControllers;
   [appDel.window addSubview:tabBarController.view];
   [viewControllers release];

}

Now as user goes to 4th tab to logout from app I have set a button to login again redirected to login view by adding code on button click as:

-(void)ClickOnLogin
{
   LoginViewController *LoginViewOb=[[LoginViewController alloc]init];
   LoginViewOb.hidesBottomBarWhenPushed = YES;
   [self.navigationController pushViewController:LoginViewOb animated:YES];
   [LoginViewOb release];
}

but as login view is loaded the previous view is still at back of login view. How can I remove this view from background.

as user licks on logout tab at the bottom he will see the label "you have successfully logout.Click here to login".code that i've implemented is in my question above. — Priyanka, Jul 10 '13 at 11:01
You should use popToRootViewController on your logout button click and push the LoginViewController again, but this time with label "Click here to login". — HRM, Jul 10 '13 at 11:47

you should disable back button on login view

- (void)viewWillAppear:(BOOL)animated
{ 
    self.navigationItem.leftBarButtonItem=nil;
    self.navigationItem.hidesBackButton=YES;
    [super viewWillAppear:animated];

}
