Question

我正在创建UITableView，其中每个单元格大小将根据我输入的文本计算。我正在计算heighForRowAtIndexPath中的Cell大小

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{
    NSString *text = [tableData objectAtIndex:[indexPath row]];

    CGSize constraint = CGSizeMake(210.0f, 20000.0f);
    size = [text sizeWithFont:[UIFont systemFontOfSize:12.0f] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

    height = MAX(size.height, 44.0f);

    return height + (CCM * 2);
}

这就是我计算每个单元格高度的方法，现在我的问题是 - 我想将图像添加到每个单元格，如评论框？像这样 Click here to see comment boxes I am looking for

您可以看到这些评论框我做的是把我的形象分成两部分第一个是顶部，它在每个单元格上运行良好，起始图像即将到来现在在修复底部我面临问题对于单元格中的小文本UILable它运行良好当UILabel中文本的大小增加时，它没有得到适当的调整

-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *identifier = @"cell";

    NSLog(@"index path %d", indexPath.row);

    MyTableCell *cell = (MyTableCell *)[tableView dequeueReusableCellWithIdentifier:identifier];

    if (cell == nil) 
    {
        cell = [[[MyTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
    }

    [cell.cellBackgroundBottom setFrame:CGRectMake(75.0f, 92.0f, 228.0f, height + 25.0f)];

    [cell.cellContent setText:(NSString*)[tableData objectAtIndex:[indexPath row]]];
    [cell.cellContent sizeToFit];

    CGRect theFrame = [cell.cellContent frame];
    theFrame.size.width = 210.0f;
    [cell.cellContent setFrame: theFrame];

    return cell;
}

我创建了一个命名MYTableCell的UITableView子类，我已经在每个单元格中定义了所需的内容。

 // Creating UILabel for cell content or comments block

        cellContent = [[UILabel alloc]initWithFrame: CGRectMake( 90.0f, 15.0f, 210.0f, 60.0f)] ;
        [cellContent setLineBreakMode:UILineBreakModeWordWrap];
        cellContent.numberOfLines = 0;
        [cellContent setMinimumFontSize:15.0f];
        [cellContent setBackgroundColor:[UIColor clearColor]];
        //   [cellContent setTextColor:[UIColor colorWithRed:73.0f green:73.0f blue:73.0f alpha:1.0f]];
        [cellContent setFont:[UIFont fontWithName:@"Helvetica" size:12.0f]];
        cellContent.textAlignment = UITextAlignmentLeft;
        [cellContent setTag:1];
        [self addSubview:cellContent];
        [cellContent release];

        cellBackgroundTop = [[UIImageView alloc] initWithFrame:CGRectMake(60.0f, 5.0f, 243.0f, 13.5f)];
        [cellBackgroundTop setImage:[UIImage imageNamed:@"comments.png"]];
        [self addSubview:cellBackgroundTop];
        [cellBackgroundTop release];

        cellBackgroundBottom = [[UIImageView alloc] initWithFrame:CGRectZero];
        [cellBackgroundBottom setImage:[UIImage imageNamed:@"Untitled-1_09.png"]];
        [self addSubview:cellBackgroundBottom];
        [cellBackgroundBottom release];

我的问题得到了回答。这是我在cellForRowAtIndexPath

中必须做的

 NSString *text = [tableData objectAtIndex:[indexPath row]];

    CGSize constraint = CGSizeMake(210.0f, 20000.0f);

    CGSize size1 = [text sizeWithFont:[UIFont systemFontOfSize:12.0f] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

    CGFloat height1 = MAX(size1.height, 44.0f);

    [cell.cellBackgroundBottom setFrame:CGRectMake(75.0f, 18.0f, 228.0f, height1 + 10.0f)];

如何将UIImage设置为UITableView Cell，根据我在UILabel中输入的文本动态计算单元格高度？
