I have a UIToolBar at the top of one of my views and the shadowing shows up on the bottom of the tool bar as I'd expect. I know UIToolbarPosition is internally set to UIToolbarPositionTop.
When I rotate my device (iPad), the tool bar grows (using auto sizing in IB) and the UIToolbarPosition changes to UIToolbarPositionBottom which flips the shadow to be at the top of the bar. If I don't have the bar resize, it remains correct, but of course doesn't stretch to match screen width.
So, what gives? What would cause the UIToolbarPosition to flip on me? This is sitting at 0,0 the whole time and only changes width based on rotation.
Extra: I've considered work arounds like using a UINavigationBar. UIAppearance is probably a no go because I do have a toolbar at the bottom too and I do want my "top" different than my "bottom"
I eventually solved this using the UIBarPositioning protocol on UIToolBarand setting the barPosition = UIBarPositionTop
