Je travaille sur le client de chat iOS. Quelqu'un peut-il m'aider s'il vous plaît avec le chat multi-utilisateurs?
J'ai implémenté le cadre XMPPFramework de Robbiehanson.
Quelqu'un peut-il me dire comment obtenir la liste des groupes et créer un groupe sur le serveur avec ce cadre?
Merci d'avance.
pour obtenir une liste de salles:
NSString* server = @"chat.shakespeare.lit"; //or whatever the server address for muc is
XMPPJID *servrJID = [XMPPJID jidWithString:server];
XMPPIQ *iq = [XMPPIQ iqWithType:@"get" to:servJID];
[iq addAttributeWithName:@"from" stringValue:[xmppStream myJID].full];
NSXMLElement *query = [NSXMLElement elementWithName:@"query"];
[query addAttributeWithName:@"xmlns" stringValue:@"http://Jabber.org/protocol/disco#items"];
[iq addChild:query];
[xmppStream sendElement:iq];
recherche la réponse dans la méthode déléguée:
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq{
DDLogVerbose(@"%@", [iq description]);
return NO;
}
pour rejoindre ou créer une salle
XMPPRoomMemoryStorage * _roomMemory = [[XMPPRoomMemoryStorage alloc]init];
NSString* roomID = @"[email protected]";
XMPPJID * roomJID = [XMPPJID jidWithString:roomID];
XMPPRoom* xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:_roomMemory
jid:roomJID
dispatchQueue:dispatch_get_main_queue()];
[xmppRoom activate:self.xmppStream];
[xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppRoom joinRoomUsingNickname:@"myNickname"
history:nil
password:nil];
recherche la réponse dans les méthodes de délégation XMPPRoom:
- (void)xmppRoomDidCreate:(XMPPRoom *)sender{
DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
}
- (void)xmppRoomDidJoin:(XMPPRoom *)sender{
DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
}
pour configurer une pièce:
après:
[xmppRoom joinRoomUsingNickname:self.xmppStream.myJID.user
history:history
password:nil];
ajouter:
[xmppRoom fetchConfigurationForm];
et vérifiez la réponse dans:
- (void)xmppRoom:(XMPPRoom *)sender didFetchConfigurationForm:(NSXMLElement *)configForm{
DDLogVerbose(@"%@: %@ -> %@", THIS_FILE, THIS_METHOD, sender.roomJID.user);
}
Passez en revue l'objet configForm
et modifiez-le si nécessaire, puis envoyez-le avec [sender configureRoomUsingOptions:newConfig];
exemple: pour changer la configuration afin de rendre la pièce persistante, vous pouvez ajouter quelque chose comme:
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"]];
}
}
[sender configureRoomUsingOptions:newConfig];
(Je ne connais pas NSXMLElement, alors il existe peut-être un meilleur moyen de changer la valeur)
Voici une version de Swift:
func joinRoom(with jidString: String, delegate: XMPPRoomDelegate) -> XMPPRoom {
let roomJID = XMPPJID(string: jidString)
let roomStorage = XMPPRoomCoreDataStorage.sharedInstance()
let room = XMPPRoom(roomStorage: roomStorage, jid: roomJID, dispatchQueue: DispatchQueue.main)!
room.activate(xmppStream)
room.addDelegate(delegate, delegateQueue: DispatchQueue.main)
// If the room is not existing, server will create one.
room.join(usingNickname: xmppStream.myJID.user, history: nil)
return room
}
// MUCRoomDelegate
public func xmppRoomDidCreate(_ sender: XMPPRoom!) {
print("xmppRoomDidCreate")
// I prefer configure right after created
sender.fetchConfigurationForm()
}
public func xmppRoomDidJoin(_ sender: XMPPRoom!) {
print("xmppRoomDidJoin")
}
public func xmppRoom(_ sender: XMPPRoom!, didFetchConfigurationForm configForm: DDXMLElement!) {
print("didFetchConfigurationForm")
let newForm = configForm.copy() as! DDXMLElement
for field in newForm.elements(forName: "field") {
if let _var = field.attributeStringValue(forName: "var") {
switch _var {
case "muc#roomconfig_persistentroom":
field.remove(forName: "value")
field.addChild(DDXMLElement(name: "value", numberValue: 1))
case "muc#roomconfig_membersonly":
field.remove(forName: "value")
field.addChild(DDXMLElement(name: "value", numberValue: 1))
// other configures
default:
break
}
}
}
sender.configureRoom(usingOptions: newForm)
}
public func xmppRoom(_ sender: XMPPRoom!, didConfigure iqResult: XMPPIQ!) {
print("didConfigure")
}
+(void)getGroupRooms{
NSError *error = nil;
NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns='http://Jabber.org/protocol/disco#items'/>" error:&error];
XMPPIQ *iq = [XMPPIQ iqWithType:@"get" to:[XMPPJID jidWithString:Jabber_groupChat_Domain_server] elementID:[[[PXMPPManager sharedInstance] xmppStream] generateUUID] child:query];
[iq addAttributeWithName:@"from" stringValue:[[[PXMPPManager sharedInstance] xmppStream] myJID].full];
[[[PXMPPManager sharedInstance] xmppStream] sendElement:iq];
