Question

我一直在努力调试这几个小时，而且我还没有在网上看到有同样问题的人。

我让删除功能按预期工作，然后在添加一些代码后，神秘地减去按钮停止运行。起初我以为他们根本没有工作，但后来发现，如果我按住我的水龙头大约5秒钟，它会转动并显示删除按钮。

桌面视图上有一些手势，但没有LongPress手势。单元格是自定义单元格，但是当我第一次使用它时，这不会导致问题。任何帮助表示赞赏。这是相关的代码：

///
/// Pushes detail view for item swiped
///
- (IBAction)cellSwipeLeft:(UISwipeGestureRecognizer *)sender {
    if (sender.state == UIGestureRecognizerStateEnded && ![self isEditing]) {
        NSIndexPath *gestureIndexPath = [self modelIndexPathForIndexPath:[self indexPathForUIGestureRecognizer:sender]];

        // swiped left
    }
}

///
/// Checks off reminder in list
///
- (IBAction)cellSwipeRight:(UISwipeGestureRecognizer *)sender {
    if (sender.state == UIGestureRecognizerStateEnded && ![self isEditing]) {
        NSIndexPath *gestureIndexPath = [self modelIndexPathForIndexPath:[self indexPathForUIGestureRecognizer:sender]];

        //swiped right
    }
}

- (IBAction)cellTap:(UITapGestureRecognizer *)sender {

    if (sender.state == UIGestureRecognizerStateEnded && ![self.tableView isEditing]) {
    NSIndexPath *gestureIndexPath = 
     [self modelIndexPathForIndexPath:[self indexPathForUIGestureRecognizer:sender]];

       // push detail view
    }
}

///
/// Makes tableview rows editable
///
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath     {
    return YES;
}

///
/// Returns editing style of tableview
///
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView     editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
    return UITableViewCellEditingStyleDelete;
}

///
/// Toggles tableview editing
///
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {

    [super setEditing:editing animated:animated];
    [self.tableView setEditing:editing animated:animated];
}

///
/// Deletes selected rows
///
- (void)tableView:(UITableView *)tableView
commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
 forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (editingStyle == UITableViewCellEditingStyleDelete)
    {
        [self deleteReminderAtIndexPath:indexPath];

        //  Animate deletion
        NSArray *indexPaths = [NSArray arrayWithObject:indexPath];
        [[self tableView] deleteRowsAtIndexPaths:indexPaths
                            withRowAnimation:UITableViewRowAnimationAutomatic];
    }
}

我发现评论中建议的点按手势会导致问题。我通过将敲击手势设置为2次触摸来实现这一点，只是为了看看发生了什么。它按预期工作，所以他们一定是互相干扰。
