Question

Problem : I am creating an iOS chat app using the XMPPFramework and an Openfire Server. However, I cannot connect to the server. I can however log in with GTalk or Facebook accounts. Furthermore, I can log in to the account on my own server using another Jabber client such as Spark.

Code : The base of my code is from the following tutorial : http://mobile.tutsplus.com/tutorials/iphone/building-a-jabber-client-for-ios-server-setup/

Here is where it connects :

- (void)setupStream {
    xmppStream = [[XMPPStream alloc] init];
    [xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
}

- (BOOL)connect {
    [self setupStream];

    NSString *jabberID = [[NSUserDefaults standardUserDefaults] stringForKey:@"userID"];
    NSString *myPassword = [[NSUserDefaults standardUserDefaults] stringForKey:@"userPassword"];

    if (![xmppStream isDisconnected]) {
        return YES;
    }

    if (jabberID == nil || myPassword == nil) { 
        return NO;
    }

    [xmppStream setMyJID:[XMPPJID jidWithString:jabberID]];
    password = myPassword;

    NSError *error = nil;
    if (![xmppStream connect:&error])
    {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" 
                                                            message:[NSString stringWithFormat:@"Can't connect to server %@", [error localizedDescription]]  
                                                           delegate:nil 
                                                  cancelButtonTitle:@"Ok" 
                                                  otherButtonTitles:nil];
        [alertView show];
        [alertView release];

        return NO;
    }

    return YES;
}

Update 19 March : NSError is never populated so it was difficult to see what the error was. However, I have debugged through the code, and found an error in QueryRecordCallback of XMPPSRVResolver. The error code is -65554. After a google for this, I have discovered this …

kDNSServiceErr_NoSuchRecord = -65554,

However, I am still unsure how to resolve this ‘NoSuchRecord’ issue.
Furthermore, the logging on the OpenFire Server implies that we are not even getting to the OpenFire Server.

The problem is likely to be your Openfire server not being on a public domain. Assuming your Openfire server is running on a private LAN server, the global DNS records will not be able to point to it.

If you have access to a publicly accessible domain, try putting the Openfire server on the machine that serves this IP.

From reading the documentation for XMPPFramework, this shouldn’t cause a problem, but it did with me!
