Method Documentation

◆ appendMessage:error:

- (void) appendMessage:	(AgoraChatMessage *_Nonnull)	aMessage
error:	(AgoraChatError **_Nullable)	pError

Inserts a message to the end of a conversation in local database.

To insert the message correctly, ensure that the conversation ID of the message is the same as that of the conversation.

After a message is inserted, the SDK will automatically update attributes of the conversation, including latestMessage.

Parameters

aMessage	The message instance.
pError	The error information if the method fails: Error.

◆ deleteAllMessages:

- (void) deleteAllMessages: (AgoraChatError **_Nullable) pError

Deletes all the messages in the conversation from the memory and local database.

Parameters

pError The error information if the method fails: Error.

◆ deleteMessageWithId:error:

- (void) deleteMessageWithId:	(NSString *_Nonnull)	aMessageId
error:	(AgoraChatError **_Nullable)	pError

Deletes a message from the local database.

Parameters

aMessageId	The ID of the message to be deleted.
pError	The error information if the method fails: Error.

◆ insertMessage:error:

- (void) insertMessage:	(AgoraChatMessage *_Nonnull)	aMessage
error:	(AgoraChatError **_Nullable)	pError

Inserts a message to a conversation in the local database.

To insert the message correctly, ensure that the conversation ID of the message is the same as that of the conversation.

The message is inserted based on timestamp and the SDK will automatically update attributes of the conversation, including latestMessage.

Parameters

aMessage	The message instance.
pError	The error information if the method fails: Error.

◆ lastReceivedMessage

- (AgoraChatMessage *_Nullable) lastReceivedMessage

Gets the last received message.

Returns: The message instance.

◆ loadCustomMsgWithKeyword:timestamp:count:fromUser:searchDirection:

- (NSArray< AgoraChatMessage * > *_Nullable) loadCustomMsgWithKeyword:	(NSString *)	aKeyword
timestamp:	(long long)	aTimestamp
count:	(int)	aCount
fromUser:	(NSString *_Nullable)	aSender
searchDirection:	(AgoraChatMessageSearchDirection)	aDirection

Loads custom messages with keywords that the specified user sends in the conversation.

This is a synchronous method and blocks the current thread.

Parameters

aKeyword	The keywords for query. Setting it as NIL means that the SDK ignores this parameter.
aTimestamp	The starting Unix timestamp in the message for query. The unit is millisecond. After this parameter is set, the SDK retrieves messages, starting from the specified one, according to the message search direction. If this parameter is set as a negative value, the SDK retrieves from the current time.
aCount	The number of messages to load each time. If you set this parameter to a value less than 1, the SDK retrieves one message.
aSender	The message sender. Setting it as NIL means that the SDK ignores this parameter.
aDirection	The message search direction. See `AgoraChatMessageSearchDirection`.

Returns: AgoraChatMessage The message list.

fromUser:	(NSString *_Nullable)	aSender
searchDirection:	(AgoraChatMessageSearchDirection)	aDirection
completion:	(void(^)(NSArray< AgoraChatMessage * > _Nullable aMessages, AgoraChatError _Nullable aError))	aCompletionBlock

Loads custom messages with keywords that the specified user sends in the conversation.

Parameters

aKeyword	The keyword for searching the messages. Setting it as NIL means that the SDK ignores this parameter.
aTimestamp	The starting Unix timestamp in the message for query. The unit is millisecond. After this parameter is set, the SDK retrieves messages, starting from the specified one, according to the message search direction. If this parameter is set as a negative value, the SDK retrieves from the current time.
aCount	The number of messages to load each time. If you set this parameter to a value less than 1, the SDK retrieves one message.
aSender	The message sender. Setting it as NIL means that the SDK ignores this parameter.
aDirection	The message search direction. See `AgoraChatMessageSearchDirection`.
aCompletionBlock	The completion block, which contains the error message if the method fails.

to:	(long long)	aEndTimestamp
count:	(int)	aCount

Loads a certain quantity of messages sent or received in a certain period from the local database.

Messages are retrieved in the ascending order of the timestamp included in them.

This is a synchronous method and blocks the current thread.

Parameters

aStartTimestamp	The starting Unix timestamp in the message for query. The unit is millisecond.
aEndTimestamp	The ending Unix timestamp in the message for query. The unit is millisecond.
aCount	The number of messages to load each time. If you set this parameter to a value less than 1, the SDK retrieves one message.
