概述
最近很少写一下项目总结了,最近项目虽然做了很多,但是都是一些外包项目,做下来也没有什么值得总结的。最近一个项目用到了融云即时通讯,以前基本都是用环信,所以还遇到了一些问题,在此总结一下记录一下。
1 头像、昵称等用户信息(融云对这个问题有两种处理方式)
1.用户信息提供者
实现步骤(以下代码放在单例中,可以是AppDelegate,最好单独写一个单例)
首先遵守RCIMUserInfoDataSource这个协议
然后是要设置代理
[[RCIM sharedRCIM] setUserInfoDataSource:self];
最后实现代理方法:
- (void)getUserInfoWithUserId:(NSString *)userId completion:(void (^)(RCUserInfo *))completion { NSLog(@"getUserInfoWithUserId ----- %@", userId); RCUserInfo *user = [RCUserInfo new]; if (userId == nil || [userId length] == 0) { user.userId = userId; user.portraitUri = @""; user.name = @""; completion(user); return; } if ([userId isEqualToString:[UserInfo shareInstance].uid]) { NSString *urlSelf = [BASIC_URL_image stringByAppendingString:[UserInfo shareInstance].photo]; return completion([[RCUserInfo alloc] initWithUserId:userId name:[UserInfo shareInstance].nickname portrait:urlSelf]); }else { //根据存储联系人信息的模型,通过 userId 来取得对应的name和头像url,进行以下设置 [WTBaseHttpRequst postRequstWithURL:getUserHttp params:@{@"uid":[UserInfo shareInstance].uid, @"api_token":[UserInfo shareInstance].api_token, @"k_uid":userId} successBlock:^(NSDictionary *returnData) { if ([returnData[@"status"] integerValue] == 1) { NSString *urlStr = [BASIC_URL_image stringByAppendingString:returnData[@"data"][@"user"][@"photo"]]; return completion([[RCUserInfo alloc] initWithUserId:userId name:returnData[@"data"][@"user"][@"nickname"] portrait:urlStr]); }else { completion(user); } } failureBlock:^(NSString *error) { completion(user); } showHUD:NO]; } }
这个方法不需要你自己手动调用,只是当你在修改用户信息时调用
[[RCIM sharedRCIM] refreshUserInfoCache:user withUserId:[UserInfo shareInstance].uid]
方法即可
WS(weakSelf); // 修改用户信息调用 [WTBaseHttpRequst postRequstWithURL:modifyInfoHttp params:dict successBlock:^(NSDictionary *returnData) { [weakSelf MBProgressHudShowWithTextOnlyWithText:returnData[@"msg"]]; if ([returnData[@"status"] integerValue] == 1) { RCUserInfo *user = [RCUserInfo new]; user.userId = [UserInfo shareInstance].uid; user.portraitUri = [BASIC_URL_image stringByAppendingString:[UserInfo shareInstance].photo]; user.name = weakSelf.nickNameTextField.text; [[RCIM sharedRCIM] refreshUserInfoCache:user withUserId:[UserInfo shareInstance].uid]; dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ [self.navigationController popViewControllerAnimated:YES]; }); } } failureBlock:^(NSString *error) { [weakSelf MBProgressHudShowWithTextOnlyWithText:error]; } showHUD:YES];
2.在扩展消息中携带用户信息
设置发送消息时在消息体中携带用户信息(从2.4.1 之后附加用户信息之后cell默认会显示附加的用户信息的头像,即用户信息不会取用户信息提供者里提供的用户信息)
[RCIM sharedRCIM].enableMessageAttachUserInfo = YES;
你设置了enableMessageAttachUserInfo之后,可以取到
/** * 发送者信息 * **/ @property(nonatomic, strong) RCUserInfo *senderUserInfo;
当然我觉得还可以从后台获取好友关系后,我们在每次登陆后,开一个线程把好友关系请求下来存起来然后根据环信ID查找好友的昵称和头像
2 给输入框添加提示语(这个我一直觉得环信应该给了方法修改,只是我一直没有找到这个方法,所以只有自己去写了)
1.创建提示的label
_lab = [[UILabel alloc] initWithFrame:self.chatSessionInputBarControl.inputTextView.bounds]; _lab.text = @"请输入文字信息..."; _lab.textColor = [UIColor colorWithHexColor:@"dddddd"]; _lab.font = [UIFont systemFontOfSize:15]; _lab.center = CGPointMake(_lab.center.x + 15, _lab.center.y);
2.判定是否有草稿来显示和隐藏提示的label
[self.chatSessionInputBarControl.inputTextView addSubview:_lab]; if (self.chatSessionInputBarControl.draft == nil || self.chatSessionInputBarControl.draft.length == 0) { _lab.hidden = NO; }else { _lab.hidden = YES; }
3.根据输入数据来判定显示隐藏提示label
- (void)inputTextView:(UITextView *)inputTextView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { if (((inputTextView.text.length == 1 && [text isEqualToString:@""]) || (inputTextView.text.length == 0 && text.length > 0)) && range.length == 1 && range.location == 0) { _lab.hidden = NO; }else { _lab.hidden = YES; } }
3 取消输入@弹出好友列表界面,保留长按头像@方法
1.首先在AppDelegate中开启消息@功能(只支持群聊和讨论组, App需要实现群成员数据源groupMemberDataSource)
[RCIM sharedRCIM].enableMessageMentioned = YES;
然后在继承RCConversationViewController的控制器中调用
-(void)showChooseUserViewController:(void (^)(RCUserInfo *selectedUserInfo))selectedBlock cancel:(void (^)())cancelBlock { }
4 在会话列表中添加一些固定的cell(继承RCConversationListViewController)
// 对自定义cell赋值 - (RCConversationBaseCell *)rcConversationListTableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { RCCustomCell *cell = (RCCustomCell *)[[RCCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"RCCustomCell"]; RCConversationModel *model = self.conversationListDataSource[indexPath.row]; cell.nameLabel.text = model.conversationTitle; return cell; } // 添加自定义cell的数据源 - (NSMutableArray *)willReloadTableData:(NSMutableArray *)dataSource{ NSArray *arr = @[@"论坛回复和@我的", @"陌生人私信", @"幸存者部落@我的", @"问卷调查"]; for (int i = 0; i<arr.count; i++) { RCConversationModel *model = [[RCConversationModel alloc]init]; model.conversationModelType = RC_CONVERSATION_MODEL_TYPE_CUSTOMIZATION; model.conversationTitle = arr[i]; model.isTop = YES; [dataSource insertObject:model atIndex:i]; } return dataSource; } // 点击cell跳转 - (void)onSelectedTableRow:(RCConversationModelType)conversationModelType conversationModel:(RCConversationModel *)model atIndexPath:(NSIndexPath *)indexPath{ if (indexPath.row == 0) { WTForumAndConnectListViewController *chatList = (WTForumAndConnectListViewController *)[WTStoryBoardSegment instantiateViewControllerWithStoryBoardName:@"Main" identifier:@"WTForumAndConnectListViewController"]; chatList.title = @"回复和@我的"; [self.navigationController pushViewController:chatList animated:YES]; }else if (indexPath.row == 1) { WTChatListViewController *chatList = [[WTChatListViewController alloc] init]; chatList.title = @"陌生人私信"; chatList.isEnteredToCollectionViewController = YES; chatList.type = 1; chatList.friendArray = self.friendArray; [self.navigationController pushViewController:chatList animated:YES]; }else if (indexPath.row == 2) { WTChatListViewController *chatList = [[WTChatListViewController alloc] init]; chatList.title = @"幸存者部落@我的"; chatList.isEnteredToCollectionViewController = YES; chatList.type = 2; [self.navigationController pushViewController:chatList animated:YES]; }else if (indexPath.row == 3) { WTQuestionnaireViewController *questionnaire = (WTQuestionnaireViewController *)[WTStoryBoardSegment instantiateViewControllerWithStoryBoardName:@"Main" identifier:@"WTQuestionnaireViewController"]; [self.navigationController pushViewController:questionnaire animated:YES]; }else { //点击cell,拿到cell对应的model,然后从model中拿到对应的RCUserInfo,然后赋值会话属性,进入会话 if (model.conversationType == ConversationType_PRIVATE) {//单聊 WTMyConversationLisViewController *_conversationVC = [[WTMyConversationLisViewController alloc]init]; _conversationVC.conversationType = model.conversationType; _conversationVC.targetId = model.targetId; _conversationVC.title = model.conversationTitle; [self.navigationController pushViewController:_conversationVC animated:YES]; }else if (model.conversationType == ConversationType_GROUP){//群聊 WTMyConversationLisViewController *_conversationVC = [[WTMyConversationLisViewController alloc]init]; _conversationVC.conversationType = model.conversationType; _conversationVC.title = model.conversationTitle; _conversationVC.targetId = model.targetId; [self.navigationController pushViewController:_conversationVC animated:YES]; } } }
5 在任意地方获取聊天列表数量及删除列表
获取聊天列表
NSArray *privateArr = [[RCIMClient sharedRCIMClient] getConversationList:@[@(ConversationType_PRIVATE)]];
在ConversationList添加对应类型的聊天就可以获取对应类型的聊天列表删除方法类似
[[RCIMClient sharedRCIMClient] clearConversations:@[@(ConversationType_PRIVATE)]];
6 背景图
融云聊天列表没有数据的默认图片下面有点击右上角加入聊天,可是不是所有的聊天都有这个功能(我的就没有)如何没有就可以在资源文件中找到 no_message_img 这张图片用ps去掉下面的那一行字😆
7 其它
