iOS 进入程序获取群组id

EMTextMessageBody *body = [[EMTextMessageBody alloc] initWithText:@"要发送的消息"];

NSString *from = [[EMClient sharedClient] currentUsername];

 

//生成Message

EMMessage *message = [[EMMessage alloc] initWithConversationID:@"groupID" from:from to:@"

groupID" body:body ext:nil];

message.chatType = EMChatTypeGroupChat;//设置为群聊消息

消息构造正确吗?

有一个更简单的方法获取群id。
EMError *error=nil;

    NSArray *myGroups=[[EMClient sharedClient].groupManager getMyGroupsFromServerWithError:&error];

    _idArray=[NSMutableArray array];

    for (EMGroup *group in myGroups)

    {

        [_idArray addObject:group.groupId];

    }
