Feature Description
The class for the group member profile is V2TIMGroupMemberFullInfo, which contains the userID, custom information, role, and muting information of the group member.
Getting the Profile of Group Members
You can call getGroupMembersInfo (Android / iOS and macOS / Windows) to get the group member profile. This API supports passing in multiple userID values at a time to get group member profiles in batch and therefore improve the network transfer efficiency.
Sample code:
Android
iOS and macOS
Windows
List<String> userIDList = new ArrayList<>();
userIDList.add("userA");
userIDList.add("userB");
V2TIMManager.getGroupManager().getGroupMembersInfo("groupA", userIDList, new V2TIMValueCallback<List<V2TIMGroupMemberFullInfo>>() {
  @Override
  public void onSuccess(List<V2TIMGroupMemberFullInfo> v2TIMGroupMemberFullInfos) {
        // Obtained successfully
  }
﻿
  @Override
  public void onError(int code, String desc) {
        // Failed to obtain
  }
});
[[V2TIMManager sharedInstance] getGroupMembersInfo:@"groupA" memberList:@[@"user1"] succ:^(NSArray<V2TIMGroupMemberFullInfo *> *memberList) {
    // Obtained successfully
} fail:^(int code, NSString *desc) {
    // Failed to obtain
}];
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 (success_callback_) {
            success_callback_(value);
        }
    }
    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 groupID = "groupA";
V2TIMStringVector memberList;
memberList.PushBack("userA");
memberList.PushBack("userB");
﻿
auto callback = new ValueCallback<V2TIMGroupInfoVector>{};
callback->SetCallback(
    [=](const V2TIMGroupMemberFullInfoVector& groupMemberFullInfoList) {
        // Obtained successfully
        delete callback;
    },
    [=](int error_code, const V2TIMString& error_message) {
        // Failed to obtain
        delete callback;
    });
﻿
V2TIMManager::GetInstance()->GetGroupManager()->GetGroupMembersInfo(groupID, memberList, callback);
Modifying Group Member Profiles
The group owner or admin can call the setGroupMemberInfo API (Android / iOS and macOS / Windows) to modify the group name card (nameCard), custom field (customInfo), and other information of a group member.
Ordinary group members can call setGroupMemberInfo to set their group name card (nameCard) and custom field (customInfo).
To modify a custom group member field, you must configure it in advance in the Console. Configuration path: Applications > Your App > Chat > Configuration > Group Configuration > Custom Group Member Field.
Note
1. Audio-video group (AVChatRoom) doesn't store group member information, the name card of a group member cannot be set.
2. You can set up to five custom group member fields, which cannot be deleted and whose name and type cannot be changed.
Sample code:
Android
iOS and macOS
Windows
V2TIMGroupMemberFullInfo memberFullInfo = new V2TIMGroupMemberFullInfo();
// Specify a group member
memberFullInfo.setUserID("userA");
// Set the `nameCard` value to be modified
memberFullInfo.setNameCard("userA_namecard");
// Set a group member custom field
Map<String, byte[]> customMap = new HashMap<>();
customMap.put("member_key1", "value1".getBytes());
memberFullInfo.setCustomInfo(customMap);
V2TIMManager.getGroupManager().setGroupMemberInfo("groupA", memberFullInfo, new V2TIMCallback() {
  @Override
  public void onSuccess() {
        // Modified successfully
  }
﻿
  @Override
  public void onError(int code, String desc) {
        // Failed to modify
  }
});
V2TIMGroupMemberFullInfo *memberFullInfo = [[V2TIMGroupMemberFullInfo alloc] init];
// Specify a group member
memberFullInfo.userID = @"user1";
// Set the `nameCard` value to be modified
memberFullInfo.nameCard = @"user1_namecard";
// Set a group member custom field
memberFullInfo.customInfo = @{@"member_key1" : [@"value1" dataUsingEncoding:NSUTF8StringEncoding]};
[[V2TIMManager sharedInstance] setGroupMemberInfo:@"groupA" info:memberFullInfo succ:^{
    // Modified successfully
} fail:^(int code, NSString *desc) {
    // Failed to modify
}];
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_;
};
﻿
// Specify a group member
V2TIMGroupMemberFullInfo info;
info.userID = "userA";
// Set the `nameCard` value to be modified
info.nameCard = "userA_namecard";
info.modifyFlag = V2TIMGroupMemberInfoModifyFlag::V2TIM_GROUP_MEMBER_INFO_MODIFY_FLAG_NAME_CARD;
// Set a group member custom field
V2TIMCustomInfo customInfo;
std::string str{u8"value1"};
customInfo.Insert("member_key1", {reinterpret_cast<const uint8_t*>(str.data()), str.size()});
info.customInfo = customInfo;
info.modifyFlag |= V2TIMGroupMemberInfoModifyFlag::V2TIM_GROUP_MEMBER_INFO_MODIFY_FLAG_CUSTOM_INFO;
﻿
auto callback = new Callback;
callback->SetCallback(
    [=]() {
        // Modified successfully
        delete callback;
    },
    [=](int error_code, const V2TIMString& error_message) {
        // Failed to modify
