xmlファイルを解析していて、xmlファイルの「タイトル」と「要約」をテーブルビューに表示しようとしています。私はすべての「タイトル」に対してサブビューを作成し、すべての「要約」に対してサブビューを作成し、両方をセルに収めようとします。「タイトル」または「要約」のみを入力しようとすると機能しますが、両方を入力しようとすると機能しません。これは私のコードです：

- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath {

UITableViewCell *cell;
UILabel *label=nil , *secondLabel = nil;

cell = [tv dequeueReusableCellWithIdentifier:@"Cell"];
if (cell == nil)
{
    cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"Cell"] autorelease];

    label = [[UILabel alloc] initWithFrame:CGRectZero];
    [label setLineBreakMode:UILineBreakModeWordWrap];
    [label setMinimumFontSize:FONT_SIZE];
    [label setNumberOfLines:0];
    [label setFont:[UIFont boldSystemFontOfSize:FONT_SIZE]];
    [label setTag:1];


    [[cell contentView] addSubview:label];

    secondLabel = [[UILabel alloc] initWithFrame:CGRectZero];
    [secondLabel setLineBreakMode:UILineBreakModeWordWrap];
    [secondLabel setMinimumFontSize:FONT_SIZE];
    [secondLabel setNumberOfLines:0];
    [secondLabel setFont:[UIFont systemFontOfSize:FONT_SIZE]];
    [secondLabel setTag:2]; 

    [[cell contentView] addSubview:secondLabel];    
}



int storyIndex = [indexPath indexAtPosition: [indexPath length]-1];
NSString *text1 = [[stories objectAtIndex: storyIndex] objectForKey: @"title"];  
NSString *text2 = [[stories objectAtIndex: storyIndex] objectForKey: @"summary"];

CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);

CGSize size1 = [text1 sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
CGSize size2 = [text2 sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];    

if (!label)
    label = (UILabel*)[cell viewWithTag:1];
if (!secondLabel)
    secondLabel = (UILabel*)[cell viewWithTag:2];    

[label setText:text1];
[secondLabel setText:text2];

[label setFrame:CGRectMake(CELL_CONTENT_MARGIN, CELL_CONTENT_MARGIN, CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), MAX(size1.height, 44.0f))];
[secondLabel setFrame:CGRectMake(CELL_CONTENT_MARGIN, CELL_CONTENT_MARGIN, CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), MAX(size2.height, 44.0f))]; 

return cell;  }

と ：

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
NSString *text1 = [[stories objectAtIndex: storyIndex] objectForKey: @"title"];
NSString *text2 = [[stories objectAtIndex: storyIndex] objectForKey: @"summary"];    


CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);

CGSize size1 = [text1 sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
CGSize size2 = [text2 sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];    
CGFloat height = MAX(size1.height + size2.height, 44.0f);

return height + (CELL_CONTENT_MARGIN * 2);}

ありがとう！

それ以外の

cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"Cell"] autorelease];

使用する

cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"Cell"] autorelease];


//Now you can use 2 different texts    
cell.textLabel.text = @"Text1";
cell.detailTextLabel.text = @"Text2";
