title: Align UIImageView to bottom of UIScrollView
body: <p>I want to align red image at bottom of scrollview. In portrait orientation it looks fine as the height of scrollview is equal to view height.</p>
  
  <p><img src="https://i.stack.imgur.com/mVxlS.png" alt="Potrait orientation"> </p>
  
  <p>But in landscape mode it looks like this, when in landscape I want it to be completely hidden until the user scroll till the bottom of scrollview, so that the red image is always at the bottom of scroll view. Currently it looks like this in landscape mode.</p>

  <p>I have added red image as a subview of scrollview and applied bottommarginautoresizingmask to it.</p>
