IM 自定义会话

IM 自定义会话
1.进入会话列表
if ([conversation isKindOfClass:[YWCustomConversation class]]){//自定义会话
        YWCustomConversation * customConversation = (YWCustomConversation *)conversation;//conversationUnreadMessagesCount
        NSLog(@"%@",customConversation.conversationUnreadMessagesCount);//4
        [customConversation markConversationAsRead]; //自定义会话，一打开便全部标记为已读
        NSLog(@"%@",customConversation.conversationUnreadMessagesCount);//0
}


2.再来新消息时,获取同一个会话
YWCustomConversation * conversation = (YWCustomConversation *)[_ywIMKit.IMCore.getConversationService fetchConversationByConversationId:conversationID];
NSInteger unread = [conversation.conversationUnreadMessagesCount integerValue];//unread 等于 4
