Scrollview显示在多个tableview单元格中

Question

我开发了一个应用程序。我在那份申请中有一个问题
我想将scrollview添加到tableview单元格中。我使用下面的代码创建了tableview单元格。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *CellIdentifier = @"Cell";
    ExistingCasesCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[ExistingCasesCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
//Adding SwipeGestures to a cell
        UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
        [swipeRight setDirection:UISwipeGestureRecognizerDirectionRight];
        [cell addGestureRecognizer:swipeRight];
        swipeRight=nil;

        UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
        [swipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
        [cell addGestureRecognizer:swipeLeft];
        swipeLeft=nil;
    }
    cell.buttonEdit.tag=tagForButtonCustomCell*indexPath.row+0;
    [cell.buttonEdit addTarget:self action:@selector(btnOptionsClicked:) forControlEvents:UIControlEventTouchUpInside];
    cell.buttonShare.tag=tagForButtonCustomCell*indexPath.row+1;
    [cell.buttonShare addTarget:self action:@selector(btnOptionsClicked:) forControlEvents:UIControlEventTouchUpInside];
    cell.buttonAdd.tag=tagForButtonCustomCell*indexPath.row+2;
    [cell.buttonAdd addTarget:self action:@selector(btnOptionsClicked:) forControlEvents:UIControlEventTouchUpInside];
    cell.buttonDelete.tag=tagForButtonCustomCell*indexPath.row+3;
    [cell.buttonDelete addTarget:self action:@selector(btnOptionsClicked:) forControlEvents:UIControlEventTouchUpInside];
    Item *itemObject = [arrSavedDocuments objectAtIndex:indexPath.row];
    UILabel *labelDocumentName=(UILabel *)[cell.contentView viewWithTag:tagForLabelDocument];
    labelDocumentName.text=itemObject.itemTypeName;
    UILabel *labelNumOfPages=(UILabel *)[cell.contentView viewWithTag:tagForLabelNumberOfPages];
    labelNumOfPages.text=[NSString stringWithFormat:@"%d", [[itemObject.itemToPage allObjects]count]];
    UILabel *labelDate=(UILabel *)[cell.contentView viewWithTag:tagForLabelDate];
    labelDate.text=[self parseDateString:itemObject.itemCreatedTimeStamp];
    return cell;
}

这里ExistingCasesCustomCell是我的自定义单元格类
在现有casescustomcell的init方法中，我添加了滚动视图，其中子视图为4个按钮（buttonEdit、buttonShare、ButtonAnd和buttonDelete）。最初，scrollview处于隐藏位置
我的要求是每当用户在单元格上滑动时，scrollview都会显示出来。每当用户在单元格上滑动时，我就会显示滚动视图
但我的问题是，每当我滚动tableview时，其他单元格中也会显示滚动视图。我如何解决这个问题

提前谢谢，

问题的出现是因为单元格在UITableView中被回收。转到您的ExistingCasesCustomCell类，覆盖prepareforeuse方法并隐藏滚动视图。

-(void) prepareForReuse {
    self.scrollView.hidden = YES;
}
