当我的切换行的行值发生变化时，我如何 enable/disable 我的模态？

Question

我想activate/deactivate我的模式取决于我的开关行的当前值。

我有一个 SettingsViewController，用户可以在其中启用或禁用它：

class SettingsFormViewController : FormViewController, MFMailComposeViewControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        form 
            +++ Section("Messages")
            <<< SwitchRow("message_users") { row in
                row.title = "Activate messages"
            }.onChange { row in
                row.title = (row.value ?? false) ? "Deactivate messages" : "Activate messages"
                row.updateCell()
            }

现在在我的 ReloadManager 中，我想检查该行是否已启用。如果它被启用，一个模式应该出现，如果没有它不应该：


class ReloadManager {

...

private func showModalFromSettings() {

             let nav = UINavigationController()
             let ctrl = MessageFormViewController()
                 
             ctrl.preferredContentSize = CGSize(width: 600, height: 400)
             nav.pushViewController(ctrl, animated: true)
             nav.modalPresentationStyle = .popover
               
             UIApplication.shared.keyWindow?.rootViewController!.present(nav, animated: true, completion: nil)
             nav.popoverPresentationController?.sourceView = UIApplication.shared.keyWindow?.rootViewController?.view
             
    }
}

检查行是否启用然后将值传递给我的 ReloadManager 的最佳方法是什么？提前致谢！

您可以使用 UserDefaults 来保存行的状态。

 +++ Section("Messages")
                <<< SwitchRow("message_users") { row in
                    row.title = "Activate messages"
                }.onChange { row in
                    row.title = (row.value ?? false) ? "Deactivate messages" : "Activate 
messages"
                    row.updateCell()
                    UserDefaults.standard.set(row.value ?? false, forKey: "RowStatus")
                }

private func showModalFromSettings() {
             let rowStatus = UserDefaults.standard.bool(forKey: "RowStatus")
             if rowStatus {
                  //Do something when row enabled
             } else {
                 //Do something when row disabled
             }
             let nav = UINavigationController()
             let ctrl = MessageFormViewController()
                 
             ctrl.preferredContentSize = CGSize(width: 600, height: 400)
             nav.pushViewController(ctrl, animated: true)
             nav.modalPresentationStyle = .popover
               
             UIApplication.shared.keyWindow?.rootViewController!.present(nav, animated: true, completion: nil)
             nav.popoverPresentationController?.sourceView = UIApplication.shared.keyWindow?.rootViewController?.view
             
    }
}
