title: Different transition on presentModalViewController:animated:
body: <p>I present a modal view controller which is a tab bar controller with a navigation controller inside it.</p>
  
  <p>The problem is my first view has a black background and I want the new view to have a white background.</p>
  
  <p>This means I either have to have the modal view controller with a transparent background (until its completed the "slide up" animation when it shows the white background) OR I have to set the navigation controller background as white in order to make it non-transparent.</p>
  
  <p>This results in me having an extra strip of white ABOVE the navigation bar (where the network status/battery status/time bar goes). I can't get rid of this. :(</p>
  
  <p>So if I could flip the view in, or fade it in, or slide it from the right or the left or something that would be much better asthetically.</p>
  
  <p>Is there any way to do this? Or will I just have to set "animated:" to NO?</p>
  
  <p>Thanks</p>
