ios - 在 presentedViewController?.dismiss 之后快速调用 popoverPresentationControllerDidDismissPopover

Question

我创建了一个方法来关闭呈现的 View Controller ，呈现的 View Controller 确实被关闭了，但是 popoverPresentationControllerDidDismissPopover 没有被调用，我如何让它在关闭呈现的 View Controller 后调用 popoverPresentationControllerDidDismissPopover？

func dismissPresentedViewController() {
        self.presentedViewController?.dismiss(animated: true, completion: nil)
        popoverPresentationController?.delegate?.popoverPresentationControllerDidDismissPopover?(popoverPresentationController!)

    }

func popoverPresentationControllerDidDismissPopover(_ popoverPresentationController: UIPopoverPresentationController) {
        print("Here")
    }

popoverPresentationControllerDidDismissPopover 没有被调用，是的，我有 UIPopoverPresentationControllerDelegate

let popupController = storyboard?.instantiateViewController(withIdentifier: "CommentsView") as! CommentsController

popupController.modalPresentationStyle = .popover
popupController.preferredContentSize = CGSize(width: 400, height: 400)
if let popoverController = popupController.popoverPresentationController {
    popoverController.sourceView = (cell)
    popoverController.sourceRect = (cell?.bounds)!
    popoverController.permittedArrowDirections = .up
    popoverController.delegate = self
}


present(popupController, animated: true, completion: nil)

来自 Apple's documentation ……

popoverPresentationControllerDidDismissPopover(_:)

The popover presentation controller calls this method after dismissing the popover to let you know that it is no longer onscreen. The presentation controller calls this method only in response to user actions. It does not call this method if you dismiss the popover programmatically.
