环信自定义UI

1.会话列表

添加代理

[[EMClient sharedClient] addDelegate:self delegateQueue:dispatch_get_main_queue()];[[EMClient sharedClient].groupManager addDelegate:self delegateQueue:dispatch_get_main_queue()];[[EMClient sharedClient].chatManager addDelegate:self delegateQueue:dispatch_get_main_queue()];

从服务远程获取会话列表

- (void)_loadAllConversationsFromDB
{__weak typeof(self) weakSelf = self;dispatch_async(_loadDataQueue, ^{NSArray *conversations = [EMClient.sharedClient.chatManager getAllConversations];if (conversations.count == 0) {[EMClient.sharedClient.chatManager getConversationsFromServer:^(NSArray *aCoversations, EMError *aError) {if (!aError) {[weakSelf getAllConVFromServerOrDB:aCoversations];}else if(aError.code == 201){[EMClient.sharedClient loginWithUsername:weakSelf.model.easeMobUsername password:weakSelf.model.easeMobPwd completion:^(NSString *aUsername, EMError *aError) {if (!aError) {[weakSelf getData];}else{MBProgressHUDShow(@"用户信息失效，请重新登录！");}}];}else{MBProgressHUDShow(@"从服务器获取会话列表失败！");}}];}else{[weakSelf getAllConVFromServerOrDB:conversations];}});
}

实现代理方法

#pragma mark - EMChatManagerDelegate
//消息撤回
- (void)messagesDidRecall:(NSArray *)aMessages {[self _loadAllConversationsFromDB];
}
//收到消息
- (void)messagesDidReceive:(NSArray *)aMessages{if (aMessages && [aMessages count]) {EMMessage *msg = aMessages[0];if(msg.body.type == EMMessageBodyTypeText) {EMConversation *conversation = [[EMClient sharedClient].chatManager getConversation:msg.conversationId type:EMConversationTypeGroupChat createIfNotExist:NO];//群聊@“我”提醒NSString *content = [NSString stringWithFormat:@"@%@",self.model.nickname];if(conversation.type == EMConversationTypeGroupChat && [((EMTextMessageBody *)msg.body).text containsString:content]) {[conversation setRemindMe:msg.messageId];};}}[self _loadAllConversationsFromDB];
}
- (void)onConversationRead:(NSString *)from to:(NSString *)to
{[self _loadAllConversationsFromDB];
}
