그룹 검색

Overview

Only locally stored groups can be searched for, such as the list of joined groups and group profiles that have been pulled.
Note:
The local group search feature is supported only by Enhanced SDK v5.4.666 or later.
The local group search feature is only available on the IM Pro edition 、Pro Plus edition、Enterprise edition. To use it, purchase the Pro edition 、Pro Plus edition、Enterprise edition.

Searching a Local Group

Call the searchGroups API (Java / Swift / Objective-C / C++) to search a local group.
You can set the search keyword keywordList and specify the search scope to set whether to search by the groupID and groupName fields of a group.
Sample code:
Java
Swift
Objective-C
C++
V2TIMGroupSearchParam searchParam = new V2TIMGroupSearchParam();
searchParam.setKeywordList(keywordList);
searchParam.setSearchGroupID(true);
searchParam.setSearchGroupName(true);

V2TIMManager.getGroupManager().searchGroups(searchParam, new V2TIMValueCallback<List<V2TIMGroupInfo>>() {
  @Override
  public void onSuccess(List<V2TIMGroupInfo> v2TIMGroupInfos) {
        // Group found successfully
  }

  @Override
  public void onError(int code, String desc) {
      // Failed to find the group
  }
});
let param = V2TIMGroupSearchParam()
param.keywordList = ["2", "key2"]
param.isSearchGroupID = true
param.isSearchGroupName = true

V2TIMManager.shared.searchGroups(searchParam: param) { groupList in
    groupList.forEach { item in
        print( item.description)
    }
} fail: { code, desc in
    print( "searchGroups fail, \(code), \(desc)")
}
V2TIMGroupSearchParam *searchParam = [[V2TIMGroupSearchParam alloc] init];
searchParam.keywordList = @[@"keyword1", @"keyword2"];
searchParam.isSearchGroupID = YES;
searchParam.isSearchGroupName = YES;
[[V2TIMManager sharedInstance] searchGroups:searchParam succ:^(NSArray<V2TIMGroupInfo *> *groupList) {
        // Group found successfully
} fail:^(int code, NSString *desc) {
      // Failed to find the group
}];
