UITabBar and UINavigationController
<p>Let me make the question more clear.</p>

<p>I have tab bar application with navigation controller included in each tab.</p>

<p>When click the tab 2 i go to login screen. From login screen i navigate to next screen (say screen 2)  using login button. When i am on screen 2 if i cilck the tab 2 i again go to login screen. I do not want this. I want application to remain at same screen even if tab 2 is clicked again.</p>

<p>If i cilck any other tab in between then it works as expected.</p>

<p>How to achieve this??</p>
