Question

我开发了一个应用程序。我在该申请中有一个问题我想将scrollview添加到tableview单元格。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;
}

此处ExistingCasesCustomCell是我的自定义单元格类。
在ExistingCasesCustomCell的init方法中，我添加了带有子视图的scrollview作为4个按钮（buttonEdit，buttonShare，buttonAdd和buttonDelete）。最初滚动视图处于隐藏位置
我的要求是每当用户在单元格上滑动时，滚动视图应该显示。每当用户在单元格上滑动时我都会显示滚动视图。
但我的问题是每当我滚动tableview时滚动视图也会显示在其他单元格中。我该如何解决这个问题。

提前谢谢，

您的问题发生是因为单元格在UITableView中被回收。转到ExistingCasesCustomCell班级，覆盖prepareForReuse方法并隐藏滚动视图。

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

Scrollview显示在多个tableview单元格中
