Conversation Group

Overview

In some cases, you may need to group conversations, for example, into a "Product experience" or "R&D" group, which can be implemented through the following API.
Note
To use this feature, you need to purchase Premium edition.
This feature is available only in SDK enhanced edition v6.5.2803 or later.

Effect

Using this feature, you can achieve the following conversation group effects in your App:




API Description

Creating a Conversation Group

Call the createConversationGroup API (Android / iOS and macOS / Windows) to create a conversation group.
Note
Up to 20 conversation groups can be created. After this limit is exceeded, the 51010 error will be reported. Groups that are no longer used should be promptly deleted.
Attribute
Definition
Description
groupName
Conversation group name
It must be greater than 0 in length and can contain up to 32 bytes; otherwise, the 51011 error will be reported.
conversationIDList
List of conversation IDs
It cannot be empty.
Sample code:
Android
iOS and macOS
Windows
List<String> conversationIDList = new ArrayList<>();
conversationIDList.add("c2c_user1");
V2TIMManager.getConversationManager().createConversationGroup("conversation_group", conversationIDList, new V2TIMValueCallback<List<V2TIMConversationOperationResult>>() {
    @Override
    public void onSuccess(List<V2TIMConversationOperationResult> v2TIMConversationOperationResults) {
        // Created the conversation group successfully
    }

    @Override
    public void onError(int code, String desc) {
        // Failed to create the conversation group
    }
});
// Create a conversation group
[[V2TIMManager sharedInstance] createConversationGroup:@"conversation_group" conversationIDList:@[@"c2c_yahaha"] succ:^(NSArray<V2TIMConversationOperationResult *> *result) {
    // Created the conversation group successfully
} fail:^(int code, NSString *desc) {
    // Failed to create the conversation group
}];
template <class T>
class ValueCallback final : public V2TIMValueCallback<T> {
public:
    using SuccessCallback = std::function<void(const T&)>;
    using ErrorCallback = std::function<void(int, const V2TIMString&)>;

    ValueCallback() = default;
    ~ValueCallback() override = default;

    void SetCallback(SuccessCallback success_callback, ErrorCallback error_callback) {
        success_callback_ = std::move(success_callback);
        error_callback_ = std::move(error_callback);
    }

    void OnSuccess(const T& value) override {

If the target conversation group doesn't exist, the 51009 error will be reported.
Sample code:
Android
iOS and macOS
Windows
V2TIMManager.getConversationManager().deleteConversationGroup("conversation_group", new V2TIMCallback() {
    @Override
    public void onSuccess() {
        // Deleted the conversation group successfully
    }

    @Override
    public void onError(int code, String desc) {
        // Failed to delete the conversation group
    }
});
// Delete the conversation group
[[V2TIMManager sharedInstance] deleteConversationGroup:@"conversation_group" succ:^{
        // Deleted the conversation group successfully
} fail:^(int code, NSString *desc) {
        // Failed to delete the conversation group
}];
class Callback final : public V2TIMCallback {
public:
    using SuccessCallback = std::function<void()>;
    using ErrorCallback = std::function<void(int, const V2TIMString&)>;

    Callback() = default;

// Rename a conversation group
[[V2TIMManager sharedInstance] renameConversationGroup:@"conversation_group" newName:@"conversation_group_rename" succ:^{
        // Renamed the conversation group successfully
} fail:^(int code, NSString *desc) {
        // Failed to rename the conversation group
}];
class Callback final : public V2TIMCallback {
public:
    using SuccessCallback = std::function<void()>;
    using ErrorCallback = std::function<void(int, const V2TIMString&)>;

    Callback() = default;
    ~Callback() override = default;

    void SetCallback(SuccessCallback success_callback, ErrorCallback error_callback) {
        success_callback_ = std::move(success_callback);
        error_callback_ = std::move(error_callback);
    }

    void OnSuccess() override {
        if (success_callback_) {
            success_callback_();
        }
    }
    void OnError(int error_code, const V2TIMString& error_message) override {
        if (error_callback_) {
            error_callback_(error_code, error_message);
        }
    }

private:
    SuccessCallback success_callback_;
    ErrorCallback error_callback_;
};

V2TIMString oldName = u8"conversation_group";
V2TIMString newName = u8"conversation_group_rename";

auto callback = new Callback;
callback->SetCallback(
    [=]() {
        // Renamed the conversation group successfully
        delete callback;
    },
    [=](int error_code, const V2TIMString& error_message) {
        // Failed to rename the conversation group
        delete callback;
    });

V2TIMManager::GetInstance()->GetConversationManager()->RenameConversationGroup(oldName, newName, callback);

Getting the List of Conversation Groups

Call the getConversationGroupList API (Android / iOS and macOS / Windows) to get the list of conversation groups.
Sample code:

    @Override
    public void onSuccess(List<String> strings) {
        // Obtained the group list successfully
    }

    @Override
    public void onError(int code, String desc) {

        delete callback;
    },
    [=](int error_code, const V2TIMString& error_message) {
        // Failed to obtain the group list
        delete callback;
    });

V2TIMManager::GetInstance()->GetConversationManager()->GetConversationGroupList(callback);
Call the getConversationListByFilter API (Android / iOS and macOS / Windows) to get the list of conversations in a group.

    }

    @Override
    public void onError(int code, String desc) {
        // Failed to obtain the conversation list
    }
});
// Pull a specified marked conversation
V2TIMConversationListFilter *filter = [[V2TIMConversationListFilter alloc] init];
filter.groupName = @"conversation_group";
filter.count = 50;
filter.nextSeq = 0;
[[V2TIMManager sharedInstance] getConversationListByFilter:filter succ:^(NSArray<V2TIMConversation *> *list, uint64_t nextSeq, BOOL isFinished) {
   // Obtained the conversation list successfully. `list` is the conversation list.

class ValueCallback final : public V2TIMValueCallback<T> {
public:
    using SuccessCallback = std::function<void(const T&)>;
    using ErrorCallback = std::function<void(int, const V2TIMString&)>;

    ValueCallback() = default;
    ~ValueCallback() override = default;

    void SetCallback(SuccessCallback success_callback, ErrorCallback error_callback) {
        success_callback_ = std::move(success_callback);
        error_callback_ = std::move(error_callback);
    }

    void OnSuccess(const T& value) override {
        if (success_callback_) {
            success_callback_(value);
        }
    }
    void OnError(int error_code, const V2TIMString& error_message) override {
        if (error_callback_) {
            error_callback_(error_code, error_message);

public:
    using SuccessCallback = std::function<void(const T&)>;
    using ErrorCallback = std::function<void(int, const V2TIMString&)>;

    ValueCallback() = default;
    ~ValueCallback() override = default;

    void SetCallback(SuccessCallback success_callback, ErrorCallback error_callback) {
        success_callback_ = std::move(success_callback);
        error_callback_ = std::move(error_callback);
    }

    void OnSuccess(const T& value) override {
