如何使用UITableViews阻止以前的Clipping当前行？

Question

处理使用类似Pinterest的UI的项目。所以我到目前为止创建的是一个填充了自定义单元格的UITableView。每个单元格包含3个高度自定义的UIButtons来复制列。

我的最终结果是这样的：

我提出的问题是，每当我向上滚动时，前一个单元格都会被剪切，即使我已经禁用了可能生成的所有内容。剪辑看起来像这样

代码：

-(UIView*)PinterestColumnView:(NSIndexPath*)indexPath withTag:(NSInteger)tag;
{
    UIView* frameWrapper = [[[UIView alloc] initWithFrame:CGRectMake(3, 3, 94, 140)] autorelease];
    [frameWrapper setUserInteractionEnabled:NO];
    [frameWrapper setBackgroundColor:[UIColor whiteColor]];

    UIImageView* backgroundView = [[UIImageView alloc] initWithFrame:CGRectMake(5, 5, 84, 130)];
    [backgroundView setContentMode:UIViewContentModeScaleToFill];
    backgroundView.image = [UIImage imageNamed:@"pinterestbackdrop.jpg"];
    [frameWrapper addSubview:backgroundView];
    [backgroundView release];

    UIImageView* ColumnImageView = [[UIImageView alloc] initWithFrame:CGRectMake(5, 5, 84, 130)];
    [ColumnImageView setBackgroundColor:[UIColor clearColor]];
    [ColumnImageView setContentMode:UIViewContentModeScaleAspectFill];
    int ColumnAddress = (((indexPath.row*3)+tag) % self.data.count);

    [ColumnImageView setImage:[self retrieveImageFromURL:[[self.data objectAtIndex:ColumnAddress] objectForKey:@"gen_img_uri"]]];
    [frameWrapper addSubview:ColumnImageView];
    [ColumnImageView release];


    return frameWrapper;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCellStyle style = UITableViewCellStyleDefault;
    UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:sCellIdent];

    if (!cell)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:style reuseIdentifier:sCellIdent] autorelease];

        UIView* pinterestView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 200)];
        [pinterestView setBackgroundColor:[UIColor clearColor]];

        // Draw left column
        UIButton* columnButtonLeft = [UIButton buttonWithType:UIButtonTypeCustom];
        [columnButtonLeft setFrame:CGRectMake(5, 5, 100, 198)];
        [columnButtonLeft setContentMode:UIViewContentModeScaleToFill];
        [columnButtonLeft setImage:[UIImage imageNamed:@"pinterestwall.png"]];
        [columnButtonLeft setBackgroundColor:[UIColor clearColor]];
        [columnButtonLeft addButtonTarget:self action:@selector(testSelector:)];
        [columnButtonLeft setTag:0];
        int leftColumnAddress = (((indexPath.row*3)+columnButtonLeft.tag)% self.data.count);
        [columnButtonLeft addSubview:[self PinterestColumnView:indexPath withTag:[columnButtonLeft tag]]];
        [columnButtonLeft addSubview:[self makeStoryLabel:[[self.data objectAtIndex:leftColumnAddress] objectForKey:@"title"]]];
        [columnButtonLeft addSubview:[self makeStylistLabel]];
        [pinterestView addSubview:columnButtonLeft];

        // Draw Middle Column
        UIButton* columnButtonMiddle = [UIButton buttonWithType:UIButtonTypeCustom];
        [columnButtonMiddle setFrame:CGRectMake(110, 30, 100, 198)];
        [columnButtonMiddle setImage:[UIImage imageNamed:@"pinterestwall.png"]];
        [columnButtonMiddle setBackgroundColor:[UIColor clearColor]];
        [columnButtonMiddle addButtonTarget:self action:@selector(testSelector:)];
        [columnButtonMiddle setTag:1];
        int middleColumnAddress = (((indexPath.row*3)+columnButtonMiddle.tag)% self.data.count);
        [columnButtonMiddle addSubview:[self PinterestColumnView:indexPath withTag:[columnButtonMiddle tag]]];
        [columnButtonMiddle addSubview:[self makeStoryLabel:[[self.data objectAtIndex:middleColumnAddress] objectForKey:@"title"]]];
        [columnButtonMiddle addSubview:[self makeStylistLabel]];
        [pinterestView addSubview:columnButtonMiddle];


        // Draw Right Column
        UIButton* columnButtonRight = [UIButton buttonWithType:UIButtonTypeCustom];
        [columnButtonRight setFrame:CGRectMake(215, 5, 100, 198)];
        [columnButtonRight setImage:[UIImage imageNamed:@"pinterestwall.png"]];
        [columnButtonRight setBackgroundColor:[UIColor clearColor]];
        [columnButtonRight addButtonTarget:self action:@selector(testSelector:)];
        [columnButtonRight setTag:2];
        int rightColumnAddress = (((indexPath.row*3)+columnButtonRight.tag)% self.data.count);
        [columnButtonRight addSubview:[self PinterestColumnView:indexPath withTag:[columnButtonRight tag]]];
        [columnButtonRight addSubview:[self makeStoryLabel:[[self.data objectAtIndex:rightColumnAddress] objectForKey:@"title"]]];
        [columnButtonRight addSubview:[self makeStylistLabel]];
        [pinterestView addSubview:columnButtonRight];


        [cell.contentView addSubview:pinterestView];
        [pinterestView release];

        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        [cell setBackgroundColor:[UIColor clearColor]];
    }
    return cell;
}

这是我尝试过的：

    [cell setClearsContextBeforeDrawing:NO];
[cell setClipsToBounds:NO];
[cell setNeedsDisplay];
[cell setBackgroundColor:[UIColor clearColor]];
[cell setBackgroundView:nil];

任何人都有解决这个问题的神奇方法吗？
