Seeing a ViewController behind the displayed one
<p>Is it possible to view the viewcontroller behind the displayed one? I have a viewcontroller with a scrollview, which has imageviews added as subviews and would like the view that presented this viewcontroller to be visible behind the presented view controller.</p>

<p>I have set all the views, the viewcontroller view too to have a clear color background, but still there is a black background. when I dismiss the viewcontroller, I see 2 layers being dismissed. one has alpha dropped, the other not.</p>

<p>Is there an easy way to make this effect possible?</p>
