I just got around to testing this and could not confirm your results; the alert
sheet looked just fine, and looked and behaved the same way, under all
circumstances you list (different showFromRect: values, different device
orientations).
But there was one crucial difference between your code and mine - I summoned
the action sheet using a button, not with your performSelector hack. I suspect
that the hack is the cause of the problem. You must not use viewDidLoad, even
with performSelector, to do things outside the view that just loaded. m.
