a popover is a transient view that appears above other content onscreen when you tap a control or in an area. typically, a popover includes an arrow pointing to the location from which it emerged. popovers can be nonmodal or modal. a nonmodal popover is dismissed by tapping another part of the screen or a button on the popover. a modal popover is dismissed by tapping a cancel or other button on the popover.
