泡泡消息与头像图像和头像名称与时间戳

Question

我必须实施与senders AVATAR和Sender's name with time-stamps相同的冒泡消息，如下面的屏幕截图所示。

我已成功实施simple bubble type messaging。现在我有一些很好的Git-hub项目可以提供我，但我需要的是不同的东西。

我甚至使用过acanichat但没有运气。

所以有人可以建议我同样的好教程吗？或者任何人已经使用此Git-hub Library或任何其他图书馆完成此操作？

我想要一封包含senders AVATAR和Sender's name with time-stamps的气泡讯息，请查看以下图片。

你的建议很明显。

为什么不创建自己的聊天表？您只需要创建两个自定义单元格，在XIB文件的帮助下，您可以提供任何想要的外观。

使用下面的差异化和条件。

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

{

 static NSString *CellIdentifier1 = @"Cell1";
 static NSString *CellIdentifier2 = @"Cell2";

CGSize boundingSize = CGSizeMake(messageWidth-20, 10000000);
CGSize itemTextSize = [messageText sizeWithFont:[UIFont systemFontOfSize:14]
                              constrainedToSize:boundingSize
                                  lineBreakMode:NSLineBreakByWordWrapping];
float textHeight = itemTextSize.height+7;


 if (messageType isEqualToString:@"textByme"]) { 

 CustomCell1  *cell = (CustomCell1 *)[self.tableview dequeueReusableCellWithIdentifier:CellIdentifier1];

        if (cell == nil) {
            NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell1" owner:self options:nil];
            cell = [topLevelObjects objectAtIndex:0];
        }



 UIImageView *bubbleImage=[[UIImageView alloc] initWithImage:[[UIImage imageNamed:@"chatbubble"] stretchableImageWithLeftCapWidth:15 topCapHeight:15]];
        bubbleImage.tag=55;
        [cell.contentView addSubview:bubbleImage];
        [bubbleImage setFrame:CGRectMake(255-itemTextSize.width,5,itemTextSize.width+10,textHeight)];
  UITextView *messageTextview=[[UITextView alloc]initWithFrame:CGRectMake(250-itemTextSize.width,0,itemTextSize.width+15, textHeight)];
        [cell.contentView addSubview:messageTextview];
        messageTextview.editable=NO;
        messageTextview.text = messageText;
        messageTextview.dataDetectorTypes=UIDataDetectorTypeAll;
        messageTextview.textAlignment=NSTextAlignmentJustified;
        messageTextview.font=[UIFont fontWithName:@"Helvetica Neue" size:13.0];
        messageTextview.backgroundColor=[UIColor clearColor];
        messageTextview.tag=indexPath.row;
        cell.Avatar_Image.image=[UIImage imageNamed:@"avatar.png"];
        cell.time_Label.text=data.messageTime;
        cell.selectionStyle=UITableViewCellSelectionStyleNone;
        messageTextview.scrollEnabled=NO;

  return cell; 


}
else{

CustomCell2  *cell = (CustomCell2 *)[self.tableview dequeueReusableCellWithIdentifier:CellIdentifier2];

        if (cell == nil) {
            NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell2" owner:self options:nil];
            cell = [topLevelObjects objectAtIndex:0];
        }



   UIImageView *bubbleImage=[[UIImageView alloc] initWithImage:[[UIImage   imageNamed:@"chatbubble"] stretchableImageWithLeftCapWidth:15 topCapHeight:15]];
        [cell.contentView addSubview:bubbleImage];
        [bubbleImage setFrame:CGRectMake(50,5, itemTextSize.width+10, textHeight)];
        bubbleImage.tag=56;

        UITextView *messageTextview=[[UITextView alloc]initWithFrame:CGRectMake(50,0,itemTextSize.width+15, textHeight)];
        [cell.contentView addSubview:messageTextview];
        messageTextview.editable=NO;
        messageTextview.text = messageText;
        messageTextview.dataDetectorTypes=UIDataDetectorTypeAll;
        messageTextview.textAlignment=NSTextAlignmentJustified;
        messageTextview.backgroundColor=[UIColor clearColor];
        messageTextview.font=[UIFont fontWithName:@"Helvetica Neue" size:13.0];
        messageTextview.scrollEnabled=NO;
        messageTextview.tag=indexPath.row;
        cell.Avatar_Image.image=[UIImage imageNamed:@"avatar"];
        cell.time_Label.text=feed_data.messageTime;
        cell.selectionStyle=UITableViewCellSelectionStyleNone;

  return cell; 

}

}

高度：

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
float cellHeight;
        // text
        NSString *messageText = @"Your text";
        //
        CGSize boundingSize = CGSizeMake(messageWidth-20, 10000000);
        CGSize itemTextSize = [messageText sizeWithFont:[UIFont systemFontOfSize:14]
                                      constrainedToSize:boundingSize
                                          lineBreakMode:NSLineBreakByWordWrapping];

        // plain text
        cellHeight = itemTextSize.height;

        if (cellHeight<25) {

            cellHeight=25;
        }
        return cellHeight+30;
}
