How to remove a white bar from the top in iPhone
<p>I have a UITabBarController in my application. In the first view of this controller I have a UINavigatioController and user can navigate to multiple views through this NavigationController. In the rootview of this controller I have my frontview or main view of the application which have an info icon, which flips the screen to info page which is an another view in my appDelegate. So I use the following code from my appdelegate to switch to info page.</p>

<pre><code>UIView * controllersView = [aboutUsViewController view];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:window cache:YES];
[self.window addSubview:controllersView];
//[aboutUsViewController animateView];
[self.tabBarController.view removeFromSuperview];
[UIView commitAnimations];
</code></pre>

<p>My problem is when I flip, I see a very small white bar at the top. This white bar is seen only while fliping from main view that is first screen to info page and not viceversa.</p>

<p>I am confused how to remove this bar since I have a UIImage covering my whole page on the mainview.</p>

<p>How to solve this.</p>
