Load message context

Retrieve messages before and after a specified message with OpenIM iOS SDK.

Copy

After locating a message, use it as the anchor for retrieving surrounding context:

OIMFetchSurroundingMessagesReq *request = [OIMFetchSurroundingMessagesReq new];
request.startMessage = locatedMessage;
request.viewType = OIMFetchSurroundingHistoryViewTypeSearch;
request.before = 20;
request.after = 20;

[[OIMManager manager] fetchSurroundingMessages:request
                                     onSuccess:^(NSArray<OIMMessageInfo *> *messages) {
                                         [self replaceContext:messages ?: @[]];
                                     }
                                     onFailure:nil];

Choose viewType for the search or quote scenario. The result may contain fewer than before + after + 1 messages. Identify the anchor and deduplicate by clientMsgID; do not depend on a fixed array position. To retrieve the anchor first, see Find messages by ID.
