我必须使用 senders AVATAR 和 Sender's name with time-stamps 来实现气泡消息，与下面的屏幕截图相同。
我已经成功实现了简单的气泡类型消息。现在我有一些很好的 Git-hub 项目可以提供给我，但我需要的是不同的东西。
我什至用过acanichat但没有运气。
所以任何人都可以建议我很好的教程吗？或者任何人已经用这个 Git-hub Library或与任何其他图书馆？
我想要一个带有发件人头像和带有时间戳的发件人姓名的气泡消息，请看下图。
您的建议很重要。
您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，并在 XIB 文件的帮助下，您可以提供任何您想要的外观。
使用下面的微分器和条件。
- (UITableViewCell *)tableView
UITableView *)tableView cellForRowAtIndexPathNSIndexPath *)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)tableViewUITableView *)tableView heightForRowAtIndexPathNSIndexPath *)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;
}
