This is possible starting in iOS 5.0 by subclassing the abstract class UIPopoverBackgroundView
and assigning your subclass to the popoverBackgroundViewClass
property on your UIPopoverController
instance. Unfortunately there is no tintColor
property as the popover needs to use images for it’s arrow and border in order to achieve smooth animations during dynamic resizing. You can learn more about how to customize the appearance of a UIPopoverController in the UIPopoverBackgroundView Class Reference
