Corner radius for Popover view controller

Question

I want to change the corner radius of Popoverview.

Below is my code.

class PopOverViewController: UIViewController {
   override func viewDidLoad() {
      super.viewDidLoad()
   }

   override func viewWillLayoutSubviews() {
         super.viewDidLayoutSubviews()
         self.view.superview?.layer.cornerRadius = 0.0
         self.view.superview?.layer.masksToBounds = true
    }
}

I am presenting the view controller like below

if let popoverPresentationController = popOverViewController.popoverPresentationController {
            popoverPresentationController.permittedArrowDirections = .down
            popoverPresentationController.sourceView = tabBar
            popoverPresentationController.sourceRect = rect
            popoverPresentationController.delegate = self
            popoverPresentationController.canOverlapSourceViewRect = false
            popOverViewController.preferredContentSize = CGSize(width: 341, height: 68)
            self.present(popOverViewController, animated: true, completion: {
            })
        }

It always shows rounded corners.

Any help is appreciated.

I tried changing the corner radius in `viewDidAppear ` , `viewWillAppear` , still no luck. — Badrinath, Jul 19 '19 at 00:01

As of right now, there is no supported way to have a popover view controller with unrounded corners. The way that UIPopoverController works is by adding your view to a view with rounded corners that clips to bounds.

There are two ways to go around this:

Wait for popover controller to be shown then traverse its parents and set radius to 0 and clips to bounds to false. This is kind of hacky and it it might not be compatible with all versions of iOS past and future. I do not recommend this.
Create your own class that mimics the same functionality as UIPopoverController. This is the best way to solve your problem.

Please use UIPopoverBackgroundView to define the customized corner — Zou, May 13 '22 at 05:45
