Detailed Description

This protocol that defines the operations of chat.

Messages are loaded from the local database, not from the server.

Method Documentation

◆ ackConversationRead:completion:

- (void) ackConversationRead:	(NSString *_Nonnull)	conversationId
completion:	(void(^)(AgoraChatError *_Nullable aError))	aCompletionBlock

required

Sends the conversation read receipt to the server.

This method applies to one-to-one chats only.

This method call notifies the server to set the number of unread messages of the specified conversation as 0, and triggers the onConversationRead callback on the recipient's client.

To reduce the number of method calls, we recommend that you call this method when the user enters a conversation with many unread messages, and call sendMessageReadAck during a conversation to send the message read receipts.

This is an asynchronous method.

Parameters

conversationId	The conversation ID.
aCompletionBlock	The completion block, which contains the error message if the method fails.

◆ addDelegate:delegateQueue:

- (void) addDelegate:	(id< AgoraChatManagerDelegate > _Nullable)	aDelegate
delegateQueue:	(dispatch_queue_t _Nullable)	aQueue

required

Adds a delegate.

Parameters

aDelegate	The object that implements the protocol.
aQueue	(optional) The queue of calling delegate methods. If you want to run the app on the main thread, set this parameter as nil.

◆ addReaction:toMessage:completion:

- (void) addReaction:	(NSString *)	reaction
toMessage:	(NSString *)	messageId
completion:	(nullable void(^)(AgoraChatError *_Nullable))	completion

required

Adds a Reaction.

Parameters

reaction	The Reaction content.
messageId	The message ID.
completion	The completion block which contains the error code and error information if the method fails.
