详解iOS集成融云SDK即时通讯整理
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, span) 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
