Change background image when app rotates
<p>I am making an universal app, but only support rotation on iPad so here it goes:</p>

<p>I have a view that has a image as background. When the user rotates the iPad I fade this portrait image out in the <code>willRotateToInterfaceOrientation</code> and replaces the image with a landscape image in <code>didRotateFromInterfaceOrientation</code>, and this is working great! (If there are better ways I want to hear them, but this question is not about this though). </p>

<p>I have one button on this view that will push a new viewcontroller on the stack. This view controller also has the same "function" as the view that it was pushed from. What I need help with is: When I rotates the iPad from portrait (which was the orientation this view was pushed on from) to landscape the image in this "second" view changes as intended. However when I pop this viewcontroller off stack the "first" view still displays the image which is made for portrait and not the landscape one...I understand why but not how I should fix this.</p>

<p>Could anyone help me. Thank you for your time.</p>
