===== 消息 =====


==== 发送文本消息 ====

<code>
     //toUser 为IM服务号
      HDMessage *message = [HDMessage createTxtSendMessageWithContent:text to:toUser];
    [[HDClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
        //发送消息进度
    } completion:^(HDMessage *aMessage, HDError *aError) {
        //发送消息完成，aError为空则为发送成功
    }];
</code>

==== 发送语音消息 ====

<code>
    // duration为语音时长， toUser为IM服务号
    HDMessage *message = [HDMessage createVoiceSendMessageWithLocalPath:localPath duration:duration to:toUser];
    [[HDClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
        //发送消息进度
    } completion:^(HDMessage *aMessage, HDError *aError) {
        //发送消息完成，aError为空则为发送成功
    }];
</code>

==== 发送图片消息 ====

<code>
     // toUser为IM服务号
     HDMessage *message =[HDMessage createImageSendMessageWithData:imageData displayName:@"image" to:toUser];
    [[HDClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
        //发送消息进度
    } completion:^(HDMessage *aMessage, HDError *aError) {
        //发送消息完成，aError为空则为发送成功
    }];
</code>

==== 发送地理位置 ====

<code>
    //toUser为IM服务号  address为地址信息  latitude为纬度 longitude为经度
     HDMessage *message = [HDMessage createLocationSendMessageWithLatitude:latitude longitude:longitude address:address to:toUser];
    [[HDClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
        //发送消息进度
    } completion:^(HDMessage *aMessage, HDError *aError) {
        //发送消息完成，aError为空则为发送成功
    }];
</code>


==== 发送透传消息 ====

<code>
   //机器人转人工的地方有用到,参数为具体的action
   EMCmdMessageBody *body = [[EMCmdMessageBody alloc] initWithAction:@"TransferToKf"];
   HDMessage *message = [[HDMessage alloc] initWithConversationID:<#conversationId#> from:<#环信username#> to:<#IM 服务号#> body:body];
   //参数为type；服务器传过来的参数中的id和serviceSessionId
   ControlType *type = [[ControlType alloc] initWithValue:[weichat valueForKey:@"ctrlType"] ];
   ControlArguments *arguments = [ControlArguments new]; 
   arguments.identity = [ctrlArgs valueForKey:@"id"]; 
   arguments.sessionId = [ctrlArgs valueForKey:@"serviceSessionId"];
   ControlMessage *hcont = [ControlMessage new];
   hcont.type = type; //需要时赋值
   hcont.arguments = arguments; //需要时赋值
   [message addCompositeContent:hcont];
   [[HDClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
        //发送消息进度
    } completion:^(HDMessage *aMessage, HDError *aError) {
        //发送消息完成，aError为空则为发送成功
    }];
</code>

==== 发送扩展消息 ====

任何消息类型，均可发送扩展消息，某些功能是通过扩展消息实现(例如：指定技能组，指定客服，传递访客的昵称电话等)

<code>
      message (HDMessage *);
      NSDictionary *dic = @{@"key1":@"value1",
                            @"key2":@"value2"};
      [message addAttributeDictionary:dic];
      [[HDClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
        //发送消息进度
    } completion:^(HDMessage *aMessage, HDError *aError) {
        //发送消息完成，aError为空则为发送成功
    }];
</code>

==== 发送带访客属性的消息 ==== 

当需要为客服提供访客属性(昵称，电话等)时，需要为消息带上访客属性扩展。例如：当发送文本消息时。

<code>
//属性可以缺省
HDVisitorInfo *visitor = [[HDVisitorInfo alloc] init];
visitor.name = @"小明儿";
visitor.qq = @"12345678";
visitor.phone = @"13636362637";
visitor.companyName = @"环信";
visitor.nickName = @"风口上的猪";
visitor.email = @"abv@126.com";
visitor.desc = @"环信客服云";
HDMessage *message = [....];//构造相关消息
[message addContent:visitor]; //传访客的属性
[[HDClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
        //发送消息进度
        } completion:^(HDMessage *aMessage, HDError *aError) {
        //发送消息完成，aError为空则为发送成功
}];
</code>

==== 发送轨迹消息 ====

<code>
  // toUser为IM服务号
  HDMessage *message = [HDMessage createTxtSendMessageWithContent:@"" to:toUser];
  HDVisitorTrack *vst = [HDVisitorTrack new];
  vst.title = title;  //标题
  vst.price = price; //价格
  vst.desc = desc;//描述
  vst.imageUrl = imageUrl; //图片url
  vst.itemUrl = itemUrl; //点击图片的链接
  [message addContent:vst];
  [[HDClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
        //发送消息进度
    } completion:^(HDMessage *aMessage, HDError *aError) {
        //发送消息完成，aError为空则为发送成功
    }];
</code>

==== 发送订单消息 ====

<code>
  //toUser为IM服务号
  HDMessage *message = [HDMessage createTxtSendMessageWithContent:@"" to:toUser];
  HDOrderInfo *ord = [HDOrderInfo new];
  ord.title = title;
  ord.orderTitle = orderTitle;
  ord.price = price;
  ord.desc = desc;
  ord.imageUrl = imageUrl;
  ord.itemUrl = itemUrl;
  [message addContent:ord];
  [[HDClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
        //发送消息进度
    } completion:^(HDMessage *aMessage, HDError *aError) {
        //发送消息完成，aError为空则为发送成功
    }];
</code>

==== 指定客服消息 ====

调度时，指定某个客服。

客服账号为客服的登录邮箱地址。

<code>
HDMessage *message = [....];//构造文字消息
[message addContent:[[HDAgentIdentityInfo alloc] initWithValue:@"客服账号"]];
</code>

==== 指定技能组消息 ====

调度时，指定某个技能组。

技能组名称须和客服系统设置的技能组名称完全一致，中英文均可。

<code>
   HDMessage *message = [....];//构造文字消息
   [message addContent:[[HDQueueIdentityInfo alloc] initWithValue:@"技能组名称"]];
</code>
==== 接收消息 ====

通过注册消息监听来接收消息。

<code>
//添加消息监控，第二个参数是执行代理方法的队列，默认是主队列
[[HDClient sharedClient].chatManager addDelegate:self delegateQueue:nil];
//移除消息监控
[[HDClient sharedClient].chatManager removeDelegate:self];
- (void)messagesDidReceive:(NSArray *)aMessages{
     //收到普通消息,格式:<HDMessage *>
}
- (void)cmdMessagesDidReceive:(NSArray *)aCmdMessages{
     //收到命令消息,格式:<HDMessage *>，命令消息不存数据库，一般用来作为系统通知，例如留言评论更新，
     //会话被客服接入，被转接，被关闭提醒
}
- (void)messageStatusDidChange:(HDMessage *)aMessage error:(HDError *)aError{
     //消息的状态修改，一般可以用来刷新列表，显示最新的状态
}
- (void)messageAttachmentStatusDidChange:(HDMessage *)aMessage error:(HDError *)aError{
    //发送消息后，会调用，可以在此刷新列表，显示最新的消息
}
</code>

==== 检测消息类型 ====

<code>
message.body.type == EMMessageBodyTypeText;  //文本消息
message.body.type == EMMessageBodyTypeImage; //图片消息
message.body.type == EMMessageBodyTypeVoice; //语音消息
message.body.type == EMMessageBodyTypeFile;  //文件消息
message.body.type == EMMessageBodyTypeCmd;   //命令消息

//当文本消息时，需要其他其他的检测，可能为其他类型的消息
[HDjudgeTextMessageSubType isTrackMessage:<#HDMessage *#>] == YES;   //轨迹消息
[HDjudgeTextMessageSubType isOrderMessage:<#HDMessage *#>] == YES;   //订单消息
[HDjudgeTextMessageSubType isMenuMessage:<#HDMessage *#>] == YES;    //菜单消息
[HDjudgeTextMessageSubType isTransferMessage:<#HDMessage *#>] == YES;//转接客服
[HDjudgeTextMessageSubType isEvaluateMessage:<#HDMessage *#>] == YES;//满意度评价
</code>

==== 获取聊天记录 ====

<code>
 *  从数据库获取指定数量的消息，取到的消息按时间排序，并且不包含参考的消息，如果参考消息的ID为空，则从最新消息取
 *
 *  @param aMessageId       参考消息的ID
 *  @param count            获取的条数
 *  @param aDirection       消息搜索方向
 *  @param aCompletionBlock 完成的回调
_conversation = [[HDClient sharedClient].chatManager getConversation:<IM 服务号>];
[_conversation loadMessagesStartFromId:<#messageId#> count:<#(int)count#> searchDirection:<#HDMessageSearchDirectionUp#> completion:^(NSArray *aMessages, HDError *aError) {
        if (!aError && [aMessages count]) {
            //获取到消息aMessages
        }
    }];
</code>





===== 会话 =====

==== 获取所有会话 ====

<code>
NSArray<HDConversation *> *conversastions = [[HDClient sharedClient].chatManager loadAllConversations];
</code>

==== 删除会话及聊天记录 ====

<code>
//删除一个会话;参数:会话ID,是否删除相关的消息
[[HDClient shareClient].chatManager deleteConversation:<#conversationId#> deleteMessages:YES];
HDConversation *conversation = [[HDConversation alloc] initWithConversation:<#conversationId#>];
//删除会话中的一条消息记录;参数：消息Id,错误指针
[conversation deleteMessageWithId:<#messageId#> error:<#(HDError **)#>];
//删除会话中的所有消息（不删除会话）
[conversation deleteAllMessages:<#(HDError **)#>];
</code>

==== 获取会话未读消息数 ====

<code>
 HDConversation *conversation = [[HDClient sharedClient].chatManager getConversation:<#IM 服务号#>];
 int unreadCount = conversation.unreadMessagesCount; //获取指定会话的未读消息数
</code>

==== 未读消息数清零 ==== 

<code>
  HDConversation *conversation = [[HDClient sharedClient].chatManager getConversation:<#IM 服务号#>];
  [conversation markAllMessagesAsRead:nil];
</code>

===== 满意度评价 =====

==== 判断是否为评价消息 ====
<code>
HDExtMsgType extMsgType = [HDMessageHelper getMessageExtType:{message}];
//如类型为HDExtEvaluationMsg则为满意度评价消息
</code>

==== 评价此会话 ====
<code>
NSMutableDictionary *ctrlArgs = [NSMutableDictionary dictionaryWithDictionary:[weichat objectForKey:kMesssageExtWeChat_ctrlArgs]];
            NSLog(@"ctrlArgs--%@", ctrlArgs);
            NSMutableArray *evaluationDegree = [ctrlArgs objectForKey:kMesssageExtWeChat_ctrlArgs_evaluationDegree];
            NSDictionary *appraiseTagsDict = [evaluationDegree objectAtIndex:0];

    if (error == nil) {

}];
</code>

===== 高级功能 =====

==== 显示排队人数 ====

首先，初始化时，需要调用''option.visitorWaitCount = YES;''打开待接入访客排队人数功能。 然后实现HDChatManagerDelegate中的''visitorWaitCount''方法。

 
<code> 
 -(void)visitorWaitCount:(int)count;

// 其中：count为前面有多少人正在排队， 一般大于0时，显示排队人数，当等于0，需要隐藏掉提示。在非等待状态，count均为0
</code>
