deleteGroupAttributes (Java / Swift / Objective-C / C++) 接口可以删除指定群属性，如果 keys 字段填 null/nil ，则会清空所有的群属性。List<String> keyList = new ArrayList<>();keyList.add("key1");V2TIMManager.getGroupManager().deleteGroupAttributes("groupA", keyList, new V2TIMCallback() {@Overridepublic void onSuccess() {// 删除成功}@Overridepublic void onError(int code, String desc) {// 删除失败}});

getGroupAttributes (Java / Swift / Objective-C / C++) 接口可以获取指定群属性，如果 keys 字段填 null/nil ，则会获取所有的群属性。getGroupAttributes 接口 SDK 限制为单个登录用户 5 秒 20 次。V2TIMManager.getGroupManager().getGroupAttributes("groupA", null, new V2TIMValueCallback<Map<String, String>>() {@Overridepublic void onSuccess(Map<String, String> stringStringMap) {// 获取成功}@Overridepublic void onError(int code, String desc) {// 获取失败}});

addGroupListener 添加了群组事件监听器，群属性有任何的更新变化，都会通过 onGroupAttributeChanged (Java / Swift / Objective-C / C++) 回调出来所有的群属性字段。V2TIMManager.getInstance().addGroupListener(new V2TIMGroupListener() {@Overridepublic void onGroupAttributeChanged(String groupID, Map<String, String> groupAttributeMap) {// 群属性变更通知}});

initGroupAttributes、setGroupAttributes、deleteGroupAttributes 接口合并计算，SDK 限制为单个登录用户 5 秒 10 次，超过后回调 8511 错误码；后台限制单个登录用户 1 秒 5 次，超过后返回 10049 错误码。getGroupAttributes 接口 SDK 限制为单个登录用户 5 秒 20 次。피드백
