Objective-C Question

Members cannot get member list in a muc room

I'm using IOS XMPPFramework for our chat application and I'm creating the group and adding the selected member with the below code, and receipants succesfully joins the group.
And if I query the member list of that group admins succesfully retrieve the group's members but members cannot get the same list and instead they are receiving the below error:

<iq xmlns="jabber:client" from="250034370263@conference.chat.meeapps.com.tr" to="16503312600@chat.meeapps.com.tr/15323458207749806891286" id="FF691FF5-D12B-4BAA-AB19-84E7A2B945D4" type="error"><query xmlns="http://jabber.org/protocol/muc#admin"><item affiliation="member"/></query><error code="403" type="auth"><forbidden xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/><text xmlns="urn:ietf:params:xml:ns:xmpp-stanzas">Administrator privileges required</text></error></iq>


You can find the create and invite codes below:

- (void)xmppRoom:(XMPPRoom*)sender didFetchMembersList:(NSArray *)items
{
CLS_LOG(@"Received MemberList: %@",items);
if (sender.inviteMemberList) {
if ([sender.inviteMemberList count]) {

for (NSString *user in sender.inviteMemberList) {
[sender inviteUser:[XMPPJID jidWithString:user] withMessage:nil];
}


CLS_LOG(@"Adding Members To Group %@",sender.inviteMemberList);
XMPPIQ *addMemberIQ = [XMPPIQ addMembersToGroup:sender.inviteMemberList withElementId:[self generateMessageID] andNick:sender.nickName andGroupJid:[sender.roomJID bare]];
CLS_LOG(@"Sending IQ To Add Member: %@",addMemberIQ);
[xmppStream sendElement:addMemberIQ];
sender.inviteMemberList = nil;
}
}


}

+ (nonnull instancetype) addMembersToGroup:(NSArray *)memberList withElementId:(NSString*)elementId andNick:(NSString*)nick andGroupJid:(NSString*)groupJid
{
NSXMLElement *queryElement = [self elementWithName:@"query" xmlns:XMPPMUCAdminNamespace];

for (NSString *member in memberList) {
NSXMLElement *itemElement = [self elementWithName:@"item"];
[itemElement addAttributeWithName:@"affiliation" stringValue:@"member"];
[itemElement addAttributeWithName:@"jid" stringValue:member];

[queryElement addChild:itemElement];
}


return [self iqWithType:@"set" to:[XMPPJID jidWithString:groupJid] elementID:elementId child:queryElement];
}


[EDIT]
You can also find my room config in the below xml:

Can you help me with that problem?

[EDIT 2:]
I've changed my code like in the below code. And I also made the configuration same with you, But still the same result. Am I missing something in server side ?

- (void)xmppRoom:(XMPPRoom *)sender didFetchConfigurationForm:(NSXMLElement *)configForm{

NSXMLElement *newConfig = [configForm copy];
NSArray* fields = [newConfig elementsForName:@"field"];
for (NSXMLElement *field in fields) {
NSString *var = [field attributeStringValueForName:@"var"];

if ([var isEqualToString:@"muc#roomconfig_persistentroom"]) {
[field removeChildAtIndex:0];
[field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];

}else if ([var isEqualToString:@"muc#roomconfig_roomname"]){
[field removeChildAtIndex:0];
[field addChild:[NSXMLElement elementWithName:@"value" stringValue:sender.groupName]];

}
else if ([var isEqualToString:@"muc#roomconfig_publicroom"]){
[field removeChildAtIndex:0];
[field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"0"]];
}
else if ([var isEqualToString:@"muc#roomconfig_whois"]) {
[field removeChildAtIndex:0];
[field insertChild:[NSXMLElement elementWithName:@"value" stringValue:@"anyone"] atIndex:0];
}
else if ([var isEqualToString:@"muc#roomconfig_allow_subscription"]) {
[field removeChildAtIndex:0];
[field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
}
else if ([var isEqualToString:@"muc#roomconfig_membersonly"]){
[field removeChildAtIndex:0];
[field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
}
else if ([var isEqualToString:@"public_list"]){
[field removeChildAtIndex:0];
[field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
}
else if ([var isEqualToString:@"muc#roomconfig_allowinvites"]){
[field removeChildAtIndex:0];
[field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
}
}
CLS_LOG(@"Sending Configuration: %@",newConfig);
[sender configureRoomUsingOptions:newConfig];


if (sender.inviteMemberList) {
CLS_LOG(@"Adding Members To Group %@",sender.inviteMemberList);
XMPPIQ *addMemberIQ = [XMPPIQ addMembersToGroup:sender.inviteMemberList withElementId:[self generateMessageID] andNick:sender.nickName andGroupJid:[sender.roomJID bare]];
CLS_LOG(@"Sending IQ To Add Member: %@",addMemberIQ);
[xmppStream sendElement:addMemberIQ];
[sender fetchMembersList];

}

}

- (void)xmppRoom:(XMPPRoom*)sender didFetchMembersList:(NSArray *)items{

CLS_LOG(@"Fetched Members: %@",items);

if (sender.inviteMemberList) {
if ([sender.inviteMemberList count]) {

for (NSString *user in sender.inviteMemberList) {
[sender inviteUser:[XMPPJID jidWithString:user] withMessage:nil];
}


sender.inviteMemberList = nil;
}
}

}

Answer

Make sure you set the muc#roomconfig_whois to anyone when configuring the room.

 <field
          label='Who May Discover Real JIDs?'
          type='list-single'
          var='muc#roomconfig_whois'>
        <option label='Moderators Only'>
          <value>moderators</value>
        </option>
        <option label='Anyone'>
          <value>anyone</value>
        </option>
  </field>

[Edited 2]:

I guess I kinna figure out what was wrong. From your code, you invited users first, then add them to members.

Could you try reverse the flow. Add all to members first, and then invite. Otherwise when a user gets the invitation, the members might not be set on Xmpp Server yet.

Here is what I did:

  • Join a room, (if the room is not existing, server will create it).
  • In xmppRoomDidCreate, fetch config form.
  • Send the config form, and Add All Members right after.
  • In didConfigure, send invitations.

The flow is kind of slow, I suggest you add the settings as default settings in mod_muc. Just make sure add members before send invitation.

As you can see, there is some differences on the items:

  • muc#roomconfig_publicroom
  • public_list
  • muc#roomconfig_moderatedroom
  • muc#roomconfig_allowinvites

I tried set the "muc#roomconfig_moderatedroom" to 1, still all members can get the members list. Not sure what happened on your side.
