ios - UIBubbleTableView 从 NSBubbleData 获取 didSelectRowAtIndexPath？

Question

嗨，我正在使用 code创建聊天 View 工作正常，但我需要在单击时添加放大图像，因此在 UIBubbleTableView.m 类中我添加了以下代码以获取索引选择值。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"value of index=%@",[NSString stringWithFormat:@"%d",indexPath.row]);
    NSLog(@"value of selected section=%@",[NSString stringWithFormat:@"%@",     [[self.bubbleSection objectAtIndex:indexPath.section] objectAtIndex:indexPath.row - 1]]);

 }

它给出以下输出:

所选部分的值=

我如何从上面的 NSBubbleData 中获取文本或图像？？

此代码中传递的数据具有以下格式

//for photo
NSBubbleData *photoBubblenew = [NSBubbleData dataWithImage:image date:[NSDate dateWithTimeIntervalSinceNow:-0] type:BubbleTypeMine];

//for text
NSBubbleData *  TextBubble = [NSBubbleData dataWithText:@"Hi,Check out Iphonelover" date:[NSDate dateWithTimeIntervalSinceNow:-300] type:BubbleTypeSomeoneElse];

在此处放置标签 TAG...

 -(id)initWithText:(NSString *)text date:(NSDate *)date type:(NSBubbleType)type
{

    UIFont *font = [UIFont systemFontOfSize:[UIFont systemFontSize]];
    CGSize size = [(text ? text : @"") sizeWithFont:font constrainedToSize:CGSizeMake(220, 9999) lineBreakMode:NSLineBreakByWordWrapping];

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, size.width, size.height)];
    label.numberOfLines = 0;
    label.lineBreakMode = NSLineBreakByWordWrapping;

    label.text = (text ? text : @"");
    label.font = font;
    label.backgroundColor = [UIColor clearColor];
    label.tag=100;

    UIEdgeInsets insets = (type == BubbleTypeMine ? textInsetsMine : textInsetsSomeone);
    return [self initWithView:label date:date type:type insets:insets];}

然后在此处获取值

NSBubbleData *bubble=Chat_DATA [indexPath.row];

UIView *view=bubble.view;

UILabel *LBL=(UILabel*) [view viewWithTag:100];

NSString *msg=LBL.text;
