[MonoTouch] UIActionSheet 'Presenting action sheet clipped by its superview' warning

[Nic Wise]

Is MyViewController (the instance) in anything other than the base
window? eg inside a tabview or a toolbar?

If it's just window -> myviewcontroller, you can most likely ignore
it. Also, if you can you use all buttons, esp the bottom ones, then
you should be ok.

the problem arrises if you have a view who's parent is a tabbar
controller, and you use the view to show a sheet. Usually, the tab bar
area (bottom 40-odd pixels I think) block the action sheet, so you
can't touch the bottom buttons, even tho they appear on top of the tab
bar.
