  <p>Because when the <code>Display Zoom</code> is <code>Standard</code>, all the <code>AutoLayout</code> works perfectly and when is <code>Zoomed</code>all the <code>UIView</code>s and <code>UILabel</code>s overlaps each other and I can't find a way on code to detect when is <code>Zoomed</code> to hide some <code>UIView</code>s and some <code>UILabel</code>s</p>
