◆ CreateMergerMessage()

virtual V2TIMMessage CreateMergerMessage	(	const V2TIMMessageVector &	messageList,
		const V2TIMString &	title,
		const V2TIMStringVector &	abstractList,
		const V2TIMString &	compatibleText
	)

pure virtual

2.11 Create a combined message (supported only in 5.2.210 and later versions)

Usually when we receive a combined message, the chat screen will look like this:

|Chat History of Vinson and Lynx | – title (Title)

|Vinson: When is the new version of SDK scheduled to go online? | – abstract1 (Digest information 1)

|Lynx: Next Monday. The specific time depends on the system test result in these two days. | – abstract2 (Digest information 2)

|Vinson: OK | – abstract3 (Digest information 3)

The chat UI usually displays only the title and digest information of the combined message, and the complete combined message list will be displayed only when the user clicks the combined message on the UI.

You can create a combined message (V2TIMMessage) for multiple messages to be forwarded and call the sendMessage API to send the combined message. The procedure is as follows:

1. Call createMergerMessage to create a combined message V2TIMMessage.

2. Call sendMessage to send the forward message V2TIMMessage.

The procedure for parsing a combined message received is as follows:

1. Obtain mergerElem via V2TIMMessage.

2. Obtain title and abstractList via mergerElem for UI display.

3. When a user clicks the digest information on the UI, call downloadMessageList to get the list of forwarded messages.

Parameters

messageList	Message list (Up to 300 messages are supported. The message object must be in the V2TIM_MSG_STATUS_SEND_SUCC status. The message type cannot be V2TIMGroupTipsElem.)
title	Source of the combined message, for example, "Chat History of Vinson and Lynx" and "xxx group chat history"
abstractList	Combined message digest list (supports up to 5 digests, each containing a maximum of 100 characters) You can set digest information in different formats for different message types, for example: For a text message, the digest can be in the "sender:text" format. For an image message, the digest can be in the "sender:[image]" format. For a file message, the digest can be in the "sender:[file]" format.
compatibleText	Combined messages are compatible with text. SDKs of early versions do not support combined messages, and they will send a text message with the content compatibleText by default. The parameter cannot be empty string.

◆ CreateForwardMessage()

virtual V2TIMMessage CreateForwardMessage ( const V2TIMMessage & message )

pure virtual

2.12 Create a forward message (supported only in 5.2.210 and later versions)

If you need to forward a message, you cannot directly call the sendMessage API to send the original message. Instead, you need to call createForwardMessage to create a forward message first and send it.

Parameters

message Message object to be forwarded. The message status must be V2TIM_MSG_STATUS_SEND_SUCC. The message type cannot be V2TIMGroupTipsElem.

Returns: Forward message object. The elem content is the same as the original message.

◆ CreateTargetedGroupMessage()

virtual V2TIMMessage CreateTargetedGroupMessage	(	const V2TIMMessage &	message,
		const V2TIMStringVector &	receiverList
	)

pure virtual

2.13 Create a targeted group message（supported only in 6.0 and later versions）

If you need to send a message to a specified group member list within a group, you can create a targeted group message. Only the specified group member can receive the targeted group message.

Parameters

message	Original message object
receiverList	Message receivers

Returns: Targeted group message object

Attention

Please note：

The original message object does not support group @ message.
The message receiver list supports up to 50.
The targeted group message cannot be sent in community group and avchatroom group.
The targeted group message will not be counted into the count of unread message for a group conversation.

◆ CreateAtSignedGroupMessage()

virtual V2TIMMessage CreateAtSignedGroupMessage	(	const V2TIMMessage &	message,
		const V2TIMStringVector &	atUserList
	)

pure virtual

2.14 Create a @ signed group message（supported only in 7.0 and later versions）

If you need to send a group message with @ notification feature, you can create a @ signed group message.

Parameters

message	Original message object
atUserList	List of @ target users. To @all, please pass in the kImSDK_MesssageAtALL constant string. For example, if you want the current message to @denny, @lucy, and @all, pass in @["denny", @"lucy", kImSDK_MesssageAtALL] for atUserList.

Returns: Group @ message object

Attention

The following are use limits for atUserList:

The maximum number of @ target users is 30 by default. If this limit is exceeded, message sending will fail.
The total number of users specified by atUserList cannot exceed the default maximum number, including the case of @all.
AVChatRoom do not support sending @ messages.

◆ SendMessage()

virtual V2TIMString SendMessage	(	V2TIMMessage &	message,
		const V2TIMString &	receiver,
		const V2TIMString &	groupID,
		V2TIMMessagePriority	priority,
		bool	onlineUserOnly,
		const V2TIMOfflinePushInfo &	offlinePushInfo,
		V2TIMSendCallback *	callback
	)

pure virtual

3.1 Send an advanced message (advanced version: provides the features of specifying message priorities and push information)

Parameters

message	Message object to be sent, which needs to be created via the corresponding message creation API
receiver	Message recipient's userID. For a one-to-one message, you only need to specify this field.
groupID	Target group ID For a group chat message, you only need to specify this field.
priority	Message priorities. This field is valid only for group chat messages. You are advised to set higher priorities for important messages (such as red packet and gift messages) and set lower priorities for frequent but unimportant messages (such as like messages).
onlineUserOnly	Whether the message can be received only by online users. If this field is set to true, the message cannot be pulled in recipient historical message pulling. This field is often used to implement weak notification features such as "The other party is typing" or unimportant notifications in the group. This field is not supported by audio-video groups (AVChatRoom).
offlinePushInfo	Title and voice carried when the message pushing offline.

Returns: Unique ID of the message

Attention

Targeted group messages are supported in version 6.0 and later. If groupID and receiver are set at the same time, the message will be sent to the specified receiver in the group. If you want to send message to multiple receivers in a group, you need to call CreateTargetedGroupMessage API to create a targeted group message with multiple receivers before sending.
Before setting the offlinePushInfo field, you need to enable push via V2TIMOfflinePushManager. After push is enabled, all messages except custom messages will be pushed by default.
If you want to push custom messages as well, set the desc field in offlinePushInfo so that the information specified by desc will be displayed by default during push.
Audio-video groups (AVChatRoom) do not support the onlineUserOnly field. You need to set onlineUserOnly to false for audio-video groups (AVChatRoom).
If onlineUserOnly is set to true, the message is an online message and is not counted as an unread message.

◆ SetC2CReceiveMessageOpt()

virtual void SetC2CReceiveMessageOpt	(	const V2TIMStringVector &	userIDList,
		V2TIMReceiveMessageOpt	opt,
		V2TIMCallback *	callback
	)

pure virtual

4.1 Set the one-to-one message receiving option for specified users (batch setting supported)

Supported only in 5.3.425 and later versions.

Attention

Notes:

This API supports batch setting. You can use the userIDList field to specify up to 30 users for batch setting.
This API can be called for up to 5 times per second.

Parameters

opt There are three message receiving options: V2TIMMessage.V2TIM_RECEIVE_MESSAGE: messages will be received when the user is online, and push notifications will be received when the user is offline. V2TIMMessage.V2TIM_NOT_RECEIVE_MESSAGE: no message will be received. V2TIMMessage.V2TIM_RECEIVE_NOT_NOTIFY_MESSAGE: messages will be received when the user is online, and no push notification will be received when the user is offline.

5.1 Get historical messages (advanced API)

Parameters

option Message pulling option, which can be set to pull older or newer messages from local storage or the cloud

Attention

Notes:

If option is set to pull messages from the cloud, and the IM SDK detects that the network connection is unavailable, the IM SDK directly returns local data.
Only meeting groups (Meeting) support pulling historical messages of members before they join the groups. For audio-video groups (AVChatRoom), messages are not saved to the roaming and local databases, and therefore this API does not take effect.

◆ RevokeMessage()

virtual void RevokeMessage	(	const V2TIMMessage &	message,
		V2TIMCallback *	callback
	)

pure virtual

5.2 Recall messages

Attention

Notes:

By default, you can recall only messages that are sent within 2 minutes. You can customize the time limit for message recall via the console (Feature Configuration -> Login and Message -> Message Recall Settings).
Only common messages sent in one-to-one chats and group chats can be recalled. Messages that can be received only by online users (onlineUserOnly is set to true) and audio-video group (AVChatRoom) messages cannot be recalled.
If the sender recalls a message, the recipient will receive the V2TIMAdvancedMsgListener::OnRecvMessageRevoked callback.

◆ ModifyMessage()

virtual void ModifyMessage	(	const V2TIMMessage &	message,
		V2TIMCompleteCallback< V2TIMMessage > *	callback
	)

pure virtual

5.3 Modify message

Attention

Notes：

If the message is modified successfully, both the user and the peer user (C2C) or group member (Group) will receive the onRecvMessageModified callback.
If the message has been modified by others during the process of modifying the message, the completion will return ERR_SDK_MSG_MODIFY_CONFLICT error.
Completion returns the latest message object regardless of whether the message is modified successfully or failed.

◆ DeleteMessages()

virtual void DeleteMessages	(	const V2TIMMessageVector &	messages,
		V2TIMCallback *	callback
	)

pure virtual

5.4 Delete a message from local storage

Attention: Messages can only be deleted locally. After a message is deleted, the SDK marks the message as deleted locally, and the message can no longer be pulled via getHistoryMessage. However, after the app is uninstalled and reinstalled, the local delete marker of the message will get lost, and the message can still be pulled via getHistoryMessage.

◆ ClearC2CHistoryMessage()

virtual void ClearC2CHistoryMessage	(	const V2TIMString &	userID,
		V2TIMCallback *	callback
	)

pure virtual

5.5 Delete messages from local storage and the cloud

Attention

In addition to deleting messages from the local storage (deleteMessageFromLocalStorage), this API simultaneously deletes messages from the cloud, and the deleted messages cannot be recovered. Please note that:

Up to 30 messages can be deleted at a time.
The messages to be deleted at a time must belong to the same conversation.
This API can be called only once per second.
If the account has pulled these messages from other devices, the messages will still be stored on those devices after this API is called to delete them. That is, the operation of message deletion cannot be synchronized across multiple devices.

◆ ClearGroupHistoryMessage()

Notes:

When messages in a conversation are deleted from local storage, they are deleted simultaneously from the server.

◆ InsertGroupMessageToLocalStorage()

virtual V2TIMString InsertGroupMessageToLocalStorage	(	V2TIMMessage &	message,
		const V2TIMString &	groupID,
		const V2TIMString &	sender,
		V2TIMValueCallback< V2TIMMessage > *	callback
	)

pure virtual

5.7 Add a message to the group message list

This API is mainly used to meet the requirement of inserting informative messages, such as "you have exited the group", into a group chat conversation. Such messages need to be displayed in the chat interface but do not need to be sent to others. Messages that need to be displayed in the chat interface but do not need to be sent to others. Therefore, insertGroupMessageToLocalStorage() is equivalent to a sendMessage() API whose network sending capability is disabled.

Returns: msgID Unique ID of a message

Attention: Messages saved via this API are saved only to the local storage and will get lost after the app is uninstalled.

◆ InsertC2CMessageToLocalStorage()

virtual V2TIMString InsertC2CMessageToLocalStorage	(	V2TIMMessage &	message,

	)

pure virtual

5.8 Insert a message in a one-to-one chat

This API is mainly used to meet the requirement of inserting informative messages, such as "you have exited the group", into a one-to-one chat conversation. Such messages need to be displayed in the chat interface but do not need to be sent to the peer party. Messages that need to be displayed in the chat interface but do not need to be sent to others. Therefore, insertC2CMessageToLocalStorage() is equivalent to a sendMessage() API whose network sending capability is disabled.

Returns: msgID Unique ID of a message

Attention: Messages saved via this API are saved only to the local storage and will get lost after the app is uninstalled.
