在iOS 7中的故事板上设置UIWindow和UIview的Frame

Question

I have an application which has storyboard.
it works completely fine in 480 frame size of height.
but now i am converting it to 568 frame size for IOS 7 then it is not working.

The self.window.frame.size.height and self.view.frame.size.height is also coming 480 and its also coming in middle of the view.

It looks like this...

I am trying first time storyboard.
I changed programmatically the height of Window and View but its not working.
I tried below method in viewDidLoad but its not working too for this case

  if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
  {
      self.edgesForExtendedLayout = UIRectEdgeAll;
  }  

Any kind of help is appreciated.
Thank you.
