求助:关于环信账号中存在大写字母时conversation.latestMessage获取问题

    NSArray *conversations = [[EMClient sharedClient].chatManager getAllConversations];



    for (EMConversation *conversation in conversations) {

        EMConversation *conversation1 = [[EMClient sharedClient].chatManager getConversation:conversation.conversationId type:(EMConversationTypeChat) createIfNotExist:YES];

        NSLog(@"conversation:%@===conversation1:%@",conversation.latestMessage,conversation1.latestMessage);

    }
