If you're using a navigation controller as your tab view, UITabBar will set it back the the root controller (the bottom of the stack) when the user taps the corresponding tab.

There are a number of ways to avoid this, one of the simplest being to remove the view controller you no longer need (your login page) from the navigation stack.
