How to prevent uitabbaritem from taking me to "root" controller?

Question

In my app, I have several uiTabBarItems (like search, list of items, account). When I click on account, user is supposed to put in credentials to log in. After successful login, name of tabbaritem is changed and new view controller is pushed (Profile). However, when I click on the profile tabbaritem, login controller(root for that branch of tabbar) is presented. Is there any way to disable this navigation?

Ok I finally managed (with help of answer that Prajwal provided, you are getting +1 for that ) to solve this.

All I had do was delete my navigation trace at index 0 (so my login controller gets removed from navigation stack) by using this code:

NSMutableArray *navigationArray = [[NSMutableArray alloc] initWithArray: self.navigationController.viewControllers];

// [navigationArray removeAllObjects];    // This is just for remove all view controller from navigation stack.
[navigationArray removeObjectAtIndex: 2];  // You can pass your index here
self.navigationController.viewControllers = navigationArray;
