说明具备的需求：显示商品名，商品详情，商品价格（图中未显示），商品图片，商品链接，点击气泡跳转到链接目的。

开始上代码：

一.通过EaseBubbleView创建一个分类

EaseBubbleView+Share.m文件

添加控件约束

#import "EaseBubbleView+Share.h"
//#import <objc/runtime.h>
@implementation EaseBubbleView (Share)

                                    toItem:self.backgroundImageView
                                 attribute:NSLayoutAttributeBottom
                                multiplier:1.0
                                  constant:-5];
    
    [self.marginConstraints addObject:priceTopConstraint];
    [self.marginConstraints addObject:priceLeftConstraint];
    [self.marginConstraints addObject:priceRightConstraint];
    [self.marginConstraints addObject:priceBottomConstraint];
    
    NSLayoutConstraint *imageViewTopConstraint =
    [NSLayoutConstraint constraintWithItem:self.imageViewShare
                                 attribute:NSLayoutAttributeTop
                                 relatedBy:NSLayoutRelationEqual
                                    toItem:self.titleLabel
                                 attribute:NSLayoutAttributeTop
                                multiplier:1.0

    NSLayoutConstraint *imageViewLeadingConstraint =

                                 attribute:NSLayoutAttributeLeading
                                 relatedBy:NSLayoutRelationEqual
                                    toItem:self.backgroundImageView
                                 attribute:NSLayoutAttributeLeading
                                multiplier:1.0
                                  constant:135];
    NSLayoutConstraint *imageViewRightConstraint =
    [NSLayoutConstraint constraintWithItem:self.imageViewShare
                                 attribute:NSLayoutAttributeTrailing
                                 relatedBy:NSLayoutRelationEqual
                                    toItem:self.backgroundImageView
                                 attribute:NSLayoutAttributeTrailing
                                multiplier:1.0
                                  constant:-15];
    NSLayoutConstraint *imageViewBottomConstraint =
    [NSLayoutConstraint constraintWithItem:self.imageViewShare
                                 attribute:NSLayoutAttributeBottom
                                 relatedBy:NSLayoutRelationEqual
                                    toItem:self.backgroundImageView
                                 attribute:NSLayoutAttributeBottom
                                multiplier:1.0
                                  constant:-10];
    
    [self.marginConstraints addObject:imageViewTopConstraint];
    [self.marginConstraints addObject:imageViewLeadingConstraint];
    [self.marginConstraints addObject:imageViewRightConstraint];
    [self.marginConstraints addObject:imageViewBottomConstraint];
    
    [self addConstraints:self.marginConstraints];
    
    NSLayoutConstraint *backImageConstraint = [NSLayoutConstraint constraintWithItem:self attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:0.0f constant:260];
    
    [self.superview addConstraint:backImageConstraint];
    
}
- (void)_setupShareBubbleConstraints
{
    [self _setUpShareBubbleMarginConstraints];
}

接着设置：

-(void)setUpShareBubbleView{
    
    self.titleLabel = [[UILabel alloc]init];
    self.titleLabel.translatesAutoresizingMaskIntoConstraints = NO;
    self.titleLabel.font = [UIFont systemFontOfSize:15];
    self.titleLabel.numberOfLines = 0;
    self.titleLabel.textColor = [UIUtils colorWithHex:0x333333];
    self.titleLabel.textAlignment = NSTextAlignmentLeft;
    [self.backgroundImageView addSubview:self.titleLabel];
    
    self.content = [[UILabel alloc]init];
    self.content.font = [UIFont systemFontOfSize:12];
    self.content.numberOfLines = 0;
    self.content.textColor = [UIUtils colorWithHex:0x999999];
    self.content.translatesAutoresizingMaskIntoConstraints = NO;
    self.content.textAlignment = NSTextAlignmentLeft;
    [self.backgroundImageView addSubview:self.content];
    
    self.priceLabel = [[UILabel alloc]init];
    self.priceLabel.font = [UIFont systemFontOfSize:12];
    self.priceLabel.textColor = [UIColor redColor];
    self.priceLabel.translatesAutoresizingMaskIntoConstraints = NO;
    self.priceLabel.textAlignment = NSTextAlignmentLeft;
    [self.backgroundImageView addSubview:self.priceLabel];

    self.imageViewShare = [[UIImageView alloc]init];
    self.imageViewShare.translatesAutoresizingMaskIntoConstraints = NO;
    [self.backgroundImageView addSubview:self.imageViewShare];
    [self _setUpShareBubbleMarginConstraints];

}

- (void)updateShareMargin:(UIEdgeInsets)margin
{
    if (_margin.top == margin.top && _margin.bottom == margin.bottom && _margin.left == margin.left && _margin.right == margin.right) {
        return;
    }
    _margin = margin;
    
    [self removeConstraints:self.marginConstraints];
    [self _setUpShareBubbleMarginConstraints];
}

到这里完成了EaseBubbleView+Share.m文件

二.新建一个继承于EaseBaseMessageCell的cell

ShareInfoCell.png

ShareInfoCell.m

#import "ShareInfoCell.h"
#import "EaseBubbleView+Share.h"
static const CGFloat kCellHeight = 180.0f;
@implementation ShareInfoCell

- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier model:(id<IMessageModel>)model
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier model:model];
    
    if (self) {
        self.hasRead.hidden = YES;
        self.selectionStyle = UITableViewCellSelectionStyleNone;
    }
    
    return self;
}
- (BOOL)isCustomBubbleView:(id<IMessageModel>)model
{
    return YES;
}
- (void)setCustomModel:(id<IMessageModel>)model
{
    UIImage *image = model.image;
    if (!image) {
        [self.bubbleView.imageView sd_setImageWithURL:[NSURL URLWithString:model.fileURLPath] placeholderImage:[UIImage imageNamed:model.failImageName]];
    } else {
        _bubbleView.imageView.image = image;
    }
    
    if (model.avatarURLPath) {
        [self.avatarView sd_setImageWithURL:[NSURL URLWithString:model.avatarURLPath] placeholderImage:model.avatarImage];
    } else {
        self.avatarView.image = model.avatarImage;
    }
}
- (void)setCustomBubbleView:(id<IMessageModel>)model
{
    [_bubbleView setUpShareBubbleView];
    
    _bubbleView.imageView.image = [UIImage imageNamed:@"imageDownloadFail"];
}
- (void)updateCustomBubbleViewMargin:(UIEdgeInsets)bubbleMargin model:(id<IMessageModel>)model
{
    
    [_bubbleView updateShareMargin:bubbleMargin];
    _bubbleView.translatesAutoresizingMaskIntoConstraints = YES;
    CGFloat bubbleViewHeight = 120;// 气泡背景图高度
    CGFloat nameLabelHeight = 15;// 昵称label的高度
    if (model.isSender) {
        _bubbleView.frame =
        CGRectMake([UIScreen mainScreen].bounds.size.width - 273.5, nameLabelHeight, 213, bubbleViewHeight);
    }else{
        _bubbleView.frame = CGRectMake(55, nameLabelHeight, 213, bubbleViewHeight);
        
    }
    // 这里强制调用内部私有方法
    [_bubbleView _setUpShareBubbleMarginConstraints];
    
}
+ (CGFloat)cellHeightWithModel:(id<IMessageModel>)model
{
    return kCellHeight;
}
- (void)setModel:(id<IMessageModel>)model
{
    [super setModel:model];

    NSDictionary *ext = [[NSDictionary alloc]initWithDictionary:model.message.ext];
    //发送了商品信息的情况
    if ([ext[@"msg_type"] isEqualToString:@"msg_share"]) {
        _bubbleView.priceLabel.hidden = YES;
        NSDictionary *msgtypeDic = [[NSDictionary alloc]initWithDictionary:ext[@"msg_info"]];
        _bubbleView.titleLabel.text = msgtypeDic[@"title"];
        _bubbleView.content.text = msgtypeDic[@"content"];
        NSString *imageUrl = [NSString stringWithFormat:@"%@",msgtypeDic[@"url_image"]];
        if (imageUrl.length > 0) {
            [_bubbleView.imageViewShare sd_setImageWithURL:[NSURL URLWithString:imageUrl] placeholderImage:[UIImage imageNamed:@"goodshare_holder"]];
        }else{
            _bubbleView.imageViewShare.image = [UIImage imageNamed:@"goodshare_holder"];
        }
    }

    _hasRead.hidden = YES;//名片消息不显示已读

    
}

- (void)layoutSubviews
{
    [super layoutSubviews];
    
    NSString *imageName = self.model.isSender ? @"RedpacketCellResource.bundle/redpacket_sender_bg" : @"RedpacketCellResource.bundle/redpacket_receiver_bg";
    UIImage *image = self.model.isSender ? [[UIImage imageNamed:imageName] stretchableImageWithLeftCapWidth:30 topCapHeight:35] :
    [[UIImage imageNamed:imageName] stretchableImageWithLeftCapWidth:20 topCapHeight:35];
    // 等待接入名片的背景图片
    //    self.bubbleView.backgroundImageView.image = image;
}

三.接下来在ChatViewController.m文件中添加EaseMessageViewControllerDelegate的代理方法

- (UITableViewCell *)messageViewController:(UITableView *)tableView
                       cellForMessageModel:(id<IMessageModel>)messageModel{
    if (messageModel.bodyType == EMMessageBodyTypeText) {
        NSDictionary *ext = [[NSDictionary alloc]initWithDictionary:messageModel.message.ext];
        NSDictionary *msgtype = ext[@"msgtype"];
        //线路宝分享
        if ([ext[@"msg_type"] isEqualToString:@"msg_share"]) {

            NSString *CellIdentifier = [EaseMessageCell cellIdentifierWithModel:messageModel];
            ShareInfoCell *cell = (ShareInfoCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
            if (cell == nil) {
                
                cell = [[ShareInfoCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier model:messageModel];
                cell.selectionStyle = UITableViewCellSelectionStyleNone;
            }
            cell.model = messageModel;
            return cell;
            
        }
    }
        return nil;

}

上面这里我走了很长的一个坑，环信是根据NSString *CellIdentifier = [EaseMessageCell cellIdentifierWithModel:messageModel];来区分发送方与接收方的，之前随便定义了CellIdentifier，出现的情况是聊天的对方消息与自己发送消息气泡位置错乱。
cellIdentifierWithMode的修改：

+ (NSString *)cellIdentifierWithModel:(id<IMessageModel>)model
{
    NSString *cellIdentifier = nil;
    if (model.isSender) {
        switch (model.bodyType) {
            case EMMessageBodyTypeText:
            {
                NSDictionary *ext = [[NSDictionary alloc]initWithDictionary:model.message.ext];
                NSDictionary *msgtype = ext[@"msgtype"];
                if ([ext[@"msg_type"] isEqualToString:@"msg_share"]) {
                    cellIdentifier = EaseMessageCellIdentifierSendShare;
                }else if (msgtype.count > 0){
                    cellIdentifier = EaseMessageCellIdentifierSendShare;

                }else{
                 cellIdentifier = EaseMessageCellIdentifierSendText;
                }
           
            }
                break;
            case EMMessageBodyTypeImage:
                cellIdentifier = EaseMessageCellIdentifierSendImage;
                break;
            case EMMessageBodyTypeVideo:
                cellIdentifier = EaseMessageCellIdentifierSendVideo;
                break;
            case EMMessageBodyTypeLocation:
                cellIdentifier = EaseMessageCellIdentifierSendLocation;
                break;
            case EMMessageBodyTypeVoice:
                cellIdentifier = EaseMessageCellIdentifierSendVoice;
                break;
            case EMMessageBodyTypeFile:
                cellIdentifier = EaseMessageCellIdentifierSendFile;
                break;
            default:
                break;
        }
    }
    else{
        switch (model.bodyType) {
            case EMMessageBodyTypeText:
            {
                NSDictionary *ext = [[NSDictionary alloc]initWithDictionary:model.message.ext];
                NSDictionary *msgtype = ext[@"msgtype"];
                if ([ext[@"msg_type"] isEqualToString:@"msg_share"]) {
                    cellIdentifier = EaseMessageCellIdentifierRecvShare;
                }else if (msgtype.count > 0 ){
                    cellIdentifier = EaseMessageCellIdentifierRecvShare;
                }
                else{
                    cellIdentifier = EaseMessageCellIdentifierRecvText;
                }
            }
                break;
            case EMMessageBodyTypeImage:
                cellIdentifier = EaseMessageCellIdentifierRecvImage;
                break;
            case EMMessageBodyTypeVideo:
                cellIdentifier = EaseMessageCellIdentifierRecvVideo;
                break;
            case EMMessageBodyTypeLocation:
                cellIdentifier = EaseMessageCellIdentifierRecvLocation;
                break;
            case EMMessageBodyTypeVoice:
                cellIdentifier = EaseMessageCellIdentifierRecvVoice;
                break;
            case EMMessageBodyTypeFile:
                cellIdentifier = EaseMessageCellIdentifierRecvFile;
                break;
            default:
                break;
        }
    }
    
    return cellIdentifier;
}

EaseMessageCellIdentifierSendShare,EaseMessageCellIdentifierRecvShared的定义为：点击环信本身的EaseMessageCellIdentifierSendText进入到设置文件，可以像我改为对应的：NSString *const EaseMessageCellIdentifierSendShare = @"EaseMessageCellSendShare";NSString *const EaseMessageCellIdentifierRecvShare = @"EaseMessageCellRecvShare";
四.发送商品的详情数据

我的需求是从商品详情页点击分享直接发送给好友，通过的是正向传值方式，修改EaseMessageViewController.m里边- (instancetype)initWithConversationChatter:(NSString *)conversationChatter conversationType:(EMConversationType)conversationType withCommodyInfo:(NSDictionary *)info方法添加了withCommodyInfo:(NSDictionary *)info传递的商品详情参数

在EaseMessageViewController.m文件中使用消息为text的方式创建发送商品信息入口

//发送分享信息
-(void)sendCommodityMessageWithInfo:(NSDictionary *)info{
    NSString *url = [info objectForKey:@"url"];
    NSString *title = [info objectForKey:@"title"];
    NSString *text = [info objectForKey:@"contentText"];
    NSString *imageLocal = [info objectForKey:@"imageLocal"];
    NSString *imageUrl = [info objectForKey:@"imageUrl"];
    NSMutableDictionary *itemDic = [[NSMutableDictionary alloc]init];
    if (url) {
        [itemDic setObject:url forKey:@"item_url"];
    }
    if (title) {
        [itemDic setObject:title forKey:@"title"];
    }
    if (text) {
         [itemDic setObject:text forKey:@"contentText"];
    }
    if (imageLocal) {
        [itemDic setObject:imageLocal forKey:@"imageLocal"];
    }
    if (imageUrl) {
        [itemDic setObject:imageUrl forKey:@"imageUrl"];
    }
    NSDictionary *dic = [[NSDictionary alloc]initWithDictionary:info];
    //是客服的话要在拓展里面添加个人信息
    NSMutableDictionary *dicExt = [[NSMutableDictionary alloc]init];
    [dicExt setObject:itemDic forKey:@"msgtype"];
    [self sendTextMessage:@"" withExt:dic];
}
- (void)sendTextMessage:(NSString *)text withExt:(NSDictionary*)ext
{
    if (_commodyInfo.count > 0) {
        EMMessage *message = [EaseSDKHelper sendTextMessage:text
                                                         to:self.conversation.conversationId
                                                messageType:[self _messageTypeFromConversationType]
                                                 messageExt:ext];
        [self _sendMessage:message];
    }else{
            EMMessage *message = [EaseSDKHelper sendTextMessage:text
                                                             to:self.conversation.conversationId
                                                    messageType:[self _messageTypeFromConversationType]
                                                     messageExt:nil];
            [self _sendMessage:message];
        }
        
    }
 }

设置此时heightForRowAtIndexPath

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    id object = [self.dataArray objectAtIndex:indexPath.row];
    if ([object isKindOfClass:[NSString class]]) {
        return self.timeCellHeight;
    }
    else{
        id<IMessageModel> model = object;
        if (_delegate && [_delegate respondsToSelector:@selector(messageViewController:heightForMessageModel:withCellWidth:)]) {
            CGFloat height = [_delegate messageViewController:self heightForMessageModel:model withCellWidth:tableView.frame.size.width];
            if (height) {
                return height;
            }
        }
        if (model.bodyType == EMMessageBodyTypeText ) {
            NSDictionary *ext = [[NSDictionary alloc]initWithDictionary:model.message.ext];NSDictionary *msgtype = ext[@"msgtype"];
            //发送了商品信息的情况
            if ([ext[@"msg_type"] isEqualToString:@"msg_share"]) {
                return [ShareInfoCell cellHeightWithModel:model];
            }
            else if (msgtype.count > 0){
                return [ShareInfoCell cellHeightWithModel:model];
            }
        }
        if (_dataSource && [_dataSource respondsToSelector:@selector(isEmotionMessageFormessageViewController:messageModel:)]) {
            BOOL flag = [_dataSource isEmotionMessageFormessageViewController:self messageModel:model];
            if (flag) {
                return [EaseCustomMessageCell cellHeightWithModel:model];
            }
        }
        return [EaseBaseMessageCell cellHeightWithModel:model];
    }
}

设置气泡被点击时触发的代理方法：

- (void)messageCellSelected:(id<IMessageModel>)model
{
    if (_delegate && [_delegate respondsToSelector:@selector(messageViewController:didSelectMessageModel:)]) {
        BOOL flag = [_delegate messageViewController:self didSelectMessageModel:model];
        if (flag) {
            [self _sendHasReadResponseForMessages:@[model.message] isRead:YES];
            return;
        }
    }
    switch (model.bodyType) {
        case EMMessageBodyTypeText:{
            NSDictionary *ext = [[NSDictionary alloc]initWithDictionary:model.message.ext];
             NSDictionary *msgtype = ext[@"msgtype"];
            //发送了商品信息的情况
            if ([ext[@"msg_type"] isEqualToString:@"msg_share"]) {
                NSDictionary *msgtypeDic = [[NSDictionary alloc]initWithDictionary:ext[@"msg_info"]];
                JSViewController *view = [[JSViewController alloc]init];
                view.strTitle = @"分享信息";
                view.url = [NSString stringWithFormat:@"%@",msgtypeDic[@"url_visit"]];
                NSLog(@"链接分享：%@",view.url);
                self.hidesBottomBarWhenPushed = YES;
                [self.navigationController pushViewController:view animated:YES];
            }
            else if (msgtype.count > 0){
                NSDictionary *msgtypeDic = [[NSDictionary alloc]initWithDictionary:ext[@"msgtype"][@"track"]];
                JSViewController *view = [[JSViewController alloc]init];
                view.strTitle = @"分享信息";
                view.url = [NSString stringWithFormat:@"%@",msgtypeDic[@"item_url"]];
                NSLog(@"链接分享：%@",view.url);
                self.hidesBottomBarWhenPushed = YES;
                [self.navigationController pushViewController:view animated:YES];
            }
            
        }
            break;
        case EMMessageBodyTypeImage:
        {
            _scrollToBottomWhenAppear = NO;
            [self _imageMessageCellSelected:model];
        }
            break;
        case EMMessageBodyTypeLocation:
        {
             [self _locationMessageCellSelected:model];
        }
            break;
        case EMMessageBodyTypeVoice:
        {
            [self _audioMessageCellSelected:model];
        }
            break;
        case EMMessageBodyTypeVideo:
        {
            [self _videoMessageCellSelected:model];

        }
            break;
        case EMMessageBodyTypeFile:
        {
            _scrollToBottomWhenAppear = NO;
            [self showHint:@"Custom implementation!"];
        }
            break;
        default:
            break;
    }
}

此时完成EaseMessageViewController.m文件
五.EaseMessageCell中当点击时触发代理方法

- (void)bubbleViewTapAction:(UITapGestureRecognizer *)tapRecognizer
{
    if (tapRecognizer.state == UIGestureRecognizerStateEnded) {
        if (!_delegate) {
            return;
        }
        
        if ([self respondsToSelector:@selector(isCustomBubbleView:)] && [self isCustomBubbleView:_model]) {
            if ([_delegate respondsToSelector:@selector(messageCellSelected:)]) {
                [_delegate messageCellSelected:_model];
                return;
            }
        }
        switch (_model.bodyType) {
            case EMMessageBodyTypeText:{
                NSDictionary *ext = [[NSDictionary alloc]initWithDictionary:_model.message.ext];
                NSDictionary *msgtype = ext[@"msgtype"];
                //发送了商品信息的情况
                if ([ext[@"msg_type"] isEqualToString:@"msg_share"]) {
                    if ([_delegate respondsToSelector:@selector(messageCellSelected:)]) {
                        [_delegate messageCellSelected:_model];
                    }
                }else if (msgtype.count > 0){
                    if ([_delegate respondsToSelector:@selector(messageCellSelected:)]) {
                        [_delegate messageCellSelected:_model];
                    }
                }
            
            }
                break;
            case EMMessageBodyTypeImage:
            {
                if ([_delegate respondsToSelector:@selector(messageCellSelected:)]) {
                    [_delegate messageCellSelected:_model];
                }
            }
                break;
            case EMMessageBodyTypeLocation:
            {
                if ([_delegate respondsToSelector:@selector(messageCellSelected:)]) {
                    [_delegate messageCellSelected:_model];
                }
            }
                break;
            case EMMessageBodyTypeVoice:
            {
//                _model.isMediaPlaying = !_model.isMediaPlaying;
//                if (_model.isMediaPlaying) {
//                    [_bubbleView.voiceImageView startAnimating];
//                }
//                else{
//                    [_bubbleView.voiceImageView stopAnimating];
//                }
                if ([_delegate respondsToSelector:@selector(messageCellSelected:)]) {
                    [_delegate messageCellSelected:_model];
                }
            }
                break;
            case EMMessageBodyTypeVideo:
            {
                if ([_delegate respondsToSelector:@selector(messageCellSelected:)]) {
                    [_delegate messageCellSelected:_model];
                }
            }
                break;
            case EMMessageBodyTypeFile:
            {
                if ([_delegate respondsToSelector:@selector(messageCellSelected:)]) {
                    [_delegate messageCellSelected:_model];
                }
            }
                break;
            default:
                break;
        }
    }
}

到这里已实现完成，上面所述提供了一个思路，仅仅是按照我自己的需求设置。如果对你有用还需要你的进一步优化。第一次写简书和技术文章，可能格式什么设置不好，技术层次太浅。还需要很大的进步空间。大家一起加油吧。
