Change UIPopoverView background + arrow color

I found the solution. Subclassing is not necessary anymore with iOS8! The background can be accessed and changed like this from within the tableview -> navigation -> popoverPresentationController

    self.navigationController?.popoverPresentationController?.backgroundColor = UIColor.redColor()

More information about this in WWDC session 2014.

You can simply modify popover like this:

    let popoverViewController = self.storyboard?.instantiateViewControllerWithIdentifier("popoverSegue")    popoverViewController!.popoverPresentationController?.delegate = self    popoverViewController!.modalPresentationStyle = .Popover    let popoverSize = CGSize(width: 150, height: 60)    popoverViewController!.preferredContentSize = popoverSize    let popover = popoverViewController!.popoverPresentationController    popover?.delegate = self    popover?.permittedArrowDirections = .Up    popover?.sourceView = self.view    //change background color with arrow too!    popover?.backgroundColor = UIColor.whiteColor()    popover?.sourceRect = CGRect(x: self.view.frame.width, y: -10, width: 0, height: 0)    presentViewController(popoverViewController!, animated: true, completion: nil)

Seems like that popoverPresentationController.backgroundColor no longer works in iOS13.

Popover arrows now appear to take on the color of the popover viewController's view.backgroundColor.

Here's the whole code for the demo below:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {    if let sourceButton = sender as? UIButton, let popover = segue.destination.popoverPresentationController {        popover.sourceView = sourceButton.superview        popover.sourceRect = sourceButton.frame        popover.permittedArrowDirections = [.left]        popover.delegate = self        segue.destination.preferredContentSize = CGSize(width: 100, height: 100)        //popover.backgroundColor = sourceButton.tintColor  //old way        segue.destination.view.backgroundColor = sourceButton.tintColor  //new way    }}@IBAction func btnTap(_ sender: Any) {    performSegue(withIdentifier: "popoverSegue", sender: sender)}func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {    return .none}
