ios - 在带有操作的条形按钮项上显示徽章

Question

我的视图控制器上有一个条形按钮项目，它显示了一个弹出视图，我有一个扩展来在任何按钮上显示徽章，我试图在图标上显示徽章，但它显示了另一个视图，我想显示我的栏按钮项目上的徽章，

我试过这段代码

 func addBadge(itemvalue: String) {

       let bagButton = BadgeButton()
       bagButton.frame = CGRect(x: 0, y: 0, width: 44, height: 44)
       bagButton.tintColor = UIColor.darkGray
       bagButton.setImage(UIImage(named: "comment")?.withRenderingMode(.alwaysTemplate), for: .normal)
       bagButton.badgeEdgeInsets = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 15)
       bagButton.badge = itemvalue
       self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: bagButton)
   }

我的弹出按钮代码

 @IBAction func showPopoverButtonAction(_ sender: Any) {
    

    //get the button frame
    /* 1 */
    let button = sender as? UIButton
    let buttonFrame = button?.frame ?? CGRect.init(x: -20, y: -320, width: 200, height: 400)
 
    /* 2 */
    //Configure the presentation controller
    guard let popoverContentController = self.storyboard?.instantiateViewController(withIdentifier: "PopOverViewController") as? PopOverViewController else { return }
    popoverContentController.modalPresentationStyle = .popover

    popoverContentController.dpostID = self.postIdm
    popoverContentController.dpostTitle = self.postTitlem
    popoverContentController.duserPhone = self.muserPhone
    popoverContentController.delegate = self

    /* 3 */
    if let popoverPresentationController = popoverContentController.popoverPresentationController {
        popoverPresentationController.permittedArrowDirections = .up
        popoverPresentationController.sourceView = self.view
        popoverPresentationController.sourceRect = buttonFrame
        popoverPresentationController.delegate = self
    //    if let popoverController = popoverContentController {
    //
    //    }
        present(popoverContentController, animated: true, completion: nil)
    }
}
 

目前它是这样显示的！ 在此处输入图像描述

但我希望徽章在我的栏按钮上，而不是新按钮上！

澄清一下：带有徽章的新栏按钮是由问题中的代码生成的，评论按钮是我想在其上显示徽章的 mybutton。

弹出按钮是我想要显示徽章的按钮，而不是代码中生成的按钮
