I've got an app where I'd like to support UIInterfaceOrientationPortraitUpsideDown orientation -- basically, to hold the phone upside down.
What I'm seeing is that when I use UIView#presentModalViewController, the model window slides in from the top instead of the bottom. It works fine in both landscapes mode and the normal portait mode.
I can't seem to find any info on this anywhere -- and I know upside down portrait is not a very common mode to use for an app. Has anyone seen this behavior?
