ios - 以编程方式导航到手机上应用程序的推送通知设置

Question

我有一个带按钮的示例应用程序。单击按钮应该让用户为我的应用推送通知服务，以便能够禁用或启用它们。我知道如何使用此示例代码进行常规设置，但我认为对于通知，您可能需要一些额外的参数，例如 bundleId。

我的问题更多是关于我的应用推送通知的 URL，而不仅仅是常规设置，如下面的代码示例所示

示例代码:

@IBAction func pushNotificationSettings(button: UIButton) {
    guard let settingsUrl = URL(string: UIApplicationOpenSettingsURLString) else {
        return
    }

    if UIApplication.shared.canOpenURL(settingsUrl) {
        if #available(iOS 10.0, *) {
            UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
                print("Settings opened: \(success)") // Prints true
            })
        } else {
            // Fallback on earlier versions
        }
    }
}

iOS 10以上版本

 UNUserNotificationCenter.current().getNotificationSettings { (settings) in
        if settings.authorizationStatus == .authorized {
            // Notifications are allowed
        }
        else {
            // Either denied or notDetermined

            let alertController = UIAlertController(title: nil, message: "Do you want to change notifications settings?", preferredStyle: .alert)

            let action1 = UIAlertAction(title: "Settings", style: .default) { (action:UIAlertAction) in
                if let appSettings = NSURL(string: UIApplication.openSettingsURLString) {
                    UIApplication.shared.open(appSettings as URL, options: [:], completionHandler: nil)
                }
            }

            let action2 = UIAlertAction(title: "Cancel", style: .cancel) { (action:UIAlertAction) in
            }

            alertController.addAction(action1)
            alertController.addAction(action2)
            self.present(alertController, animated: true, completion: nil)
        }
    }
