环信IM中需要添加一个客服聊天的cell

1、首先，EaseConversationListViewController是消息列表的.m文件

在该文件的tableViewDidTriggerHeaderRefresh方法里面添加数组：

#warning 当sorted数组为空的时候添加admin到数组中；当sorted中没有admin的时候，添加一个；

if (sorted.count==0) {

EMConversation *conversation = [[EMClient sharedClient].chatManager getConversation:@"admin" type:EMConversationTypeChat createIfNotExist:YES];

[sorted  addObject:conversation];

}

BOOL existAdmin = NO;

for (EMConversation *conversation in sorted) {

if ([conversation.conversationId isEqualToString:@"admin"]) {

existAdmin = YES;

}

}

if (!existAdmin) {

EMConversation *conversation = [[EMClient sharedClient].chatManager getConversation:@"admin" type:EMConversationTypeChat createIfNotExist:YES];

[sorted insertObject:conversation atIndex:0];

}

#warning end

2、其次，在我们自己的MessageListViewController里面，添加逻辑：

conversationListViewController：didSelectConversationModel：方法中添加如下判断：

if (conversationModel) {

EMConversation *conversation = conversationModel.conversation;

if (conversation) {

ChatViewController *chatController = [[ChatViewController alloc] initWithConversationChatter:conversation.conversationId conversationType:conversation.type];

chatController.title = conversationModel.title;

chatController.hidesBottomBarWhenPushed = YES;

[self.navigationController pushViewController:chatController animated:YES];

//            }

}

}else{

#warning 情感客服

ChatViewController *chatController = [[ChatViewController alloc] initWithConversationChatter:@"admin" conversationType:EMConversationTypeChat];

chatController.title = conversationModel.title;

chatController.hidesBottomBarWhenPushed = YES;

[self.navigationController pushViewController:chatController animated:YES];

#warning end｝

3、返回EaseConversationListViewController中在tableView的didSelect代理方法中添加

if (_delegate && [_delegate respondsToSelector:@selector(conversationListViewController:didSelectConversationModel:)]) {

//        EaseConversationModel *model = [self.dataArray objectAtIndex:indexPath.row];

//        [_delegate conversationListViewController:self didSelectConversationModel:model];

#warning 修改cell的策略

if (indexPath.row == 0) {

[_delegate conversationListViewController:self didSelectConversationModel:nil];

}else{

EaseConversationModel *model = [self.dataArray objectAtIndex:indexPath.row];

[_delegate conversationListViewController:self didSelectConversationModel:model];

}

｝
