在 BarButtonItem Swift 上添加徽章计数图标 [重复]

Question

我想在UINavigationBar 中使用过的图标上添加一个徽章图标。

到目前为止，我已经完成了

let threeDotButton = UIBarButtonItem(image:UIImage(named: "ic_more.png")?.withRenderingMode(.alwaysOriginal), style: .plain, target: self, action: #selector(DashboardViewController.threeDotImageClick))
    let notificationButton = UIBarButtonItem(image:UIImage(named: "ic_notifications.png")?.withRenderingMode(.alwaysOriginal), style: .plain, target: self, action: #selector(DashboardViewController.notificationImageClick))
    self.tabBarController?.navigationItem.rightBarButtonItems = [threeDotButton,notificationButton]

    let title = UILabel()
    title.text = "Dashboard"
    self.tabBarController?.navigationItem.leftBarButtonItem = UIBarButtonItem.init(customView: title)

    if let fontstyle = UIFont(name: "Roboto", size: 30) {
        self.tabBarController?.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.font: fontstyle]
    }

我想在通知按钮上添加计数徽章。我搜索了它，但我没有得到适当的解决方案。谁能解释我如何做到这一点并实现它

https://github.com/TanguyAladenise/BBBadgeBarButtonItem 试试这个 pod，它可能会满足您的要求，但它是用 Objective C 编写的，但相当容易使用！！！
