# You don't have to reapply styles to all UIViews, if you want to optimize,
# another way to do it is tag the views you need to restyle in your stylesheet,
# then only reapply the tagged views, like so:
def logo(st)
  st.frame = {t: 10, w: 200, h: 96, centered: :horizontal}
  st.image = image.resource('logo')
  st.tag(:reapply_style)
end

# Then in willAnimateRotationToInterfaceOrientation
rmq(:reapply_style).reapply_styles
