Popovers and Presented Views
A popover can present a view controller internally; you’ll specify a modalPresentationStyle of UIModalPresentationCurrentContext, because otherwise the presented view will be fullscreen by default. You’ll also specify a transition style of UIModalTransitionStyleCoverVertical — with any other transition style, your app will crash with this message: “Application tried to present inside popover with transition style other than UIModalTransitionStyleCoverVertical.” The presented view controller’s modalInPopover is automatically set to YES. (You can subvert this by setting the presented view controller’s modalInPopover to NO after it is presented, but you probably shouldn’t.)
If a presented view inside a popover proves troublesome — I’ve encountered some bugs connected with this arrangement — I suggest trying an alternative interface, such as replacing the popover controller’s view controller with a different view controller.
