title: Convert UIKeyboardFrameEndUserInfoKey to View or Window Coordinates
body: <p>For the constant <code>UIKeyboardFrameEndUserInfoKey</code>, in the Apple docs it says: </p>
  
  <blockquote>
    <p>These coordinates do not take into account any rotation factors
    applied to the window’s contents as a result of interface orientation
    changes. Thus, you may need to convert the rectangle to window
    coordinates (using the convertRect:fromWindow: method) or to view
    coordinates (using the convertRect:fromView: method) before using it.</p>
  </blockquote>
  
  <p>So if I use <code>[view1 convertRect:rect fromView:view2]</code></p>
  
  <p>What would I insert for the above parameters to get it to convert the rotation values correctly? ie:</p>
  
  <p>view1 = ?
  rect = ? (the keyboard frame I'm assuming)
  view2 = ?</p>
  
  <p>Been trying some things and getting some funny stuff.</p>
