How to completely colorize UIPopoverPresentationCo

问题:

I'm working with a Day and Night Mode for an app. The problem is, when just setting the background color of a view AND THEN using it as "presenting as popover" there are little white artifacts (see the picture)

Is there an easy way to fix this? Do I may have to write my own UIView?

回答1:

You can set the UIPopoverPresentationController's backgroundColor. If that isn't sufficient, you will have to customize your popover's UIPopoverBackgroundView. This gives you control of the entire popover background, including the little triangle.

Here is some code to supplement matt's answer.

popoverController.popoverPresentationController?.backgroundColor = myColor

or

self.navigationController?.popoverPresentationController?.backgroundColor = myColor
