Ios 网间网操作系统。表视图单元格滑动努力工作

我有自定义的表格视图单元格。此代码用于刷卡删除：

    return reportingCellIndexPath != indexPath;
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    NSInteger result = [self.messagesModel numberOfDifferentDayDatesInMessages];
    return result;
}

    NSDate *sectionDate = [self.messagesModel dayDateAtNumber:section];
    NSInteger rowsCount = [self.messagesModel numberOfMessagesWithDayDate:sectionDate];
    return rowsCount;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSInteger realMessageIndex = [self.messagesModel fullMessageIndexForMessageWithDayDateNumber:indexPath.section index:indexPath.row];


    SDMessage *message = [self.messagesModel messageAtIndex:realMessageIndex];
//    SDMessage *message = [self.messagesModel messageAtIndex:indexPath.row withDayDateAtNumber:indexPath.section];
    static NSString *messageCellId = @"messageCellId";
    SDMessageCell *_messageCell = [tableView dequeueReusableCellWithIdentifier:messageCellId];
    if (_messageCell == nil) {
        _messageCell = [[SDMessageCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:messageCellId];
    }
    [_messageCell rebuildWithMessage:message];
    _messageCell.delegate = self;
    if ([reportingCellIndexPath isEqual:indexPath] &&
        ![_messageCell reportViewIsShowing]) {
        [_messageCell showReportViewWithMessagesModel:self.messagesModel messageIndex:realMessageIndex];
    } else if ([_messageCell reportViewIsShowing]) {

    return _messageCell;

但几乎总是在刷卡时不显示删除按钮（有时会显示删除按钮）。有人知道为什么吗

我试着调试这个东西，通过调试器检查所有视图，它们只有系统手势识别器（平移、轻触、长按、边缘）

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle != UITableViewCellEditingStyleDelete)
        return;

    // perform the delete!
}
