So what I am really doing is... I have a login page, when proper login session took place, Its navigating to another view. It contains Tab bar. So what I did is, I made a separate class for customizing 'UITabbarController'. And now I see a white screen on the top and below is the view of that class.
Can anybody help me out?
Are you subclassing UITTabBarController? It is not something you would normally want to do.
A better option is to create your second viewcontroller and add a normal UITabBarController onto that viewcontroller's view.
