删除 UITableView 行时删除通知 (Swift)

Question

我有一个包含多个 UITableview 的视图控制器。我想当从表视图中删除一行时删除与该行关联的通知，这是我的代码，但我收到错误 Index out of range 如果有人想测试它，这里是我项目的 link : https://files.fm/f/nwx8e7je

我的代码：它在没有简单字符串的情况下工作，但在索引行中出现错误。

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

    if editingStyle == .delete {

        if tableView == ScheduleTableView{


            let defaults = UserDefaults.standard
            var myarray = defaults.stringArray(forKey: "ScheduleArray") ?? [String]()
            var myarray2 = defaults.stringArray(forKey: "ScheduleTimeArray") ?? [String]()

          // Remove Row
            myarray.remove(at: indexPath.row)
            myarray2.remove(at: indexPath.row)
            defaults.set(myarray, forKey: "ScheduleArray")
            defaults.set(myarray2, forKey: "ScheduleTimeArray")
            ScheduleTableView.deleteRows(at: [indexPath], with: .fade)
            UserDefaults.standard.synchronize()



           // Remove Notification
            let center = UNUserNotificationCenter.current()
            let arrayToSearch = myarray[indexPath.row] as String
            center.getPendingNotificationRequests { (notifications) in
                for item in notifications {
                    if(item.identifier.contains(arrayToSearch)) {
                        center.removePendingNotificationRequests(withIdentifiers: [item.identifier])
                    }
                }
            }


        }

        if tableView == GoalsTableView{


        }
 }

删除此行let arrayToSearch = myarray[indexPath.row] as String 并改用已移除的项目，因为您已经在 myarray.remove(at: indexPath.row)

移除了项目

代码如下：

   func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

            if editingStyle == .delete {

            if tableView == ScheduleTableView{

               // Here is my code but it gives me an error, first you need to add a row with the add button
                let defaults = UserDefaults.standard
                var myarray = defaults.stringArray(forKey: "ScheduleArray") ?? [String]()

                print(myarray)
                let removedItem =  myarray.remove(at: indexPath.row)
                defaults.set(myarray, forKey: "ScheduleArray")
                ScheduleTableView.deleteRows(at: [indexPath], with: .fade)

                // Remove Notification
                let center = UNUserNotificationCenter.current()
                center.getPendingNotificationRequests { (notifications) in
                    for item in notifications {
                        if(item.identifier.contains(removedItem)) {
                            center.removePendingNotificationRequests(withIdentifiers: [item.identifier])
                        }
                    }
                }


            }

            if tableView == GoalsTableView{



            }
        }
