Monotouch“滑动删除"CommitEditingStyle 未触发 [英] Monotouch "Swipe To Delete" CommitEditingStyle Not Firing

问题描述

我正在尝试在 uitableview 中实现滑动删除"功能.我遵循了其他教程/论坛并扩展了 UITableViewSource.在该类中，我覆盖了以下方法:

I am trying to implement "swipe to delete" functionality in a uitableview. I have followed other tutorials/forums and extended UITableViewSource. Within that class I have overridden the following methods:

public override void CommitEditingStyle(UITableView tableView, UITableViewCellEditingStyle editingStyle, NSIndexPath indexPath)
{
   if (editingStyle == UITableViewCellEditingStyle.Delete)
   {
       tableItems.RemoveAt(indexPath.Row);
       tableView.DeleteRows(new [] { indexPath }, UITableViewRowAnimation.Fade);
   }
}

public override UITableViewCellEditingStyle EditingStyleForRow(UITableView tableView, NSIndexPath indexPath)
{
    return UITableViewCellEditingStyle.Delete;
}

public override bool CanEditRow(UITableView tableView, NSIndexPath indexPath)
{
    return true;
}

我相信这些是我唯一需要的方法.但是，当我执行滑动手势时，会调用 CanEditRow 和 EditingStyleForRow 方法，但从未调用 CommitEditingStyle.任何帮助将非常感激.谢谢.

I believe these are the only methods I should need. However when I perform a swipe gesture, the CanEditRow and EditingStyleForRow methods are called but CommitEditingStyle is never called. Any help would be much appreciated. Thanks.

推荐答案

我正在回答我自己的问题.事实证明我的列表视图比它的容器大，所以删除按钮只是隐藏在屏幕外.脸掌.

I'm answering my own question. It turns out my listview was larger than its container so the delete buttons were simply hidden offscreen. Face palm.
