An XMPP Framework in Objective-C for Mac and iOS

I think the title is illustrating enough. I want XMPPFramework to work ( like a service ) in background and receive messages even when app is not in active state. I have set xmppStream.enableBackgroundingOnSocket = YES; But no progress here. The app goes to background, it still receives messages ( and shows notifications ) for a few seconds, but if it be inactive for a few seconds ( and idle also ( no incoming message ) ) it would no longer work in the background. I have trying logging and saw that the app is sending keep-alive packets, within a few seconds after receiving last message ( last activity ) , but if there be no activity for a few time, it stops sending keep-alives and the app wouldn't be notified and work anymore. Just in case it matters, I have set "keep alive sending interval" to 5 seconds.

I really appreciate any quick help. Thanks a lot

Apple recently announced that Starting June 1, 2016 all apps submitted to the App Store must support IPv6-only networking. I set up a network following Apple's documentation instructions in [https://developer.apple.com/library/mac/documentation/NetworkingInternetWeb/Conceptual/NetworkingOverview/UnderstandingandPreparingfortheIPv6Transition/UnderstandingandPreparingfortheIPv6Transition.html#//apple_ref/doc/uid/TP40010220-CH213-SW16], and when trying to use the library the GCDAsyncSocket socket fails to connect. After investigating a bit the issue seems to be that the XMPP server is returning both IPv4 and IPv6 addresses, but the socket is only trying to connect with the preferred one, which is IPv4. When it fails to connect, it does not retry with the IPv6 address.

I'm not really sure if this is an issue that should be fixed in the GCDAsyncSocket library or here in the XMPP one. A possible solution would be to set IPv6 as the preferred address, but right now that is not possible as the XMPPStream class is not exposing the socket as a property, nor does it provide a method to set this configuration.

Any help and guidance is really appreciated

I guys I found this issue when upgrading to the latest version of XMPPFramework. ClassName: DDXMLNode.h Module: KissXML

#if !(TARGET_IPHONE_SIMULATOR)
@import libxml;
#else
@import libxmlSimu;
#endif

Compiler mark line 4 with an error explaining: Module 'libxmlSimu' not found.

How can I solve this issue? Thanks a lot, Dario

I have added to the Bridging file XMPPLastActivity.h file and in Swift file I did the next:

let abc = XMPPLastActivity()
let a = abc.sendLastActivityQueryToJID(user.jid)
print("A is: \(a)")

but it returns me response like

 1686F740-C50C-477B-BAE2-02C897826B97

How can I return it in human readable format?

First, sorry for my bad English. I'm using XMPPFramework(version3.6) to write a ios program. As the title mentioned, the second time when i logged in, In the "xmppStreamDidDisconnect:withError:" delegate method, i got below error: error=[Error Domain=GCDAsyncSocketErrorDomain Code=4 "Read operation timed out" UserInfo=0x1c5e54a0 {NSLocalizedDescription=Read operation timed out}]

Note: it's not always happen, sometimes, i could log in again. But most of the time i got above errors.

in the program, what i'm doing is as below:

1. call oldSchoolSecureConnect method to login. ※Because i'm using 55223 as the port number.
2. call goOffline(send presence to unavailable), and then disconnectAfterSending to logout.
3. call oldSchoolSecureConnect method again to login.

the source code like below: ====================Initialization=======================

xmppStream = [XMPPStream alloc] init];
[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];

[xmppStream setHostName:@"xxxx"];
[xmppStream setHostPort:55223];

allowSelfSignedCertificates = YES;
allowSSLHostNameMismatch = YES;

====================connect/disconnect=======================

- (BOOL)connect
{
    if (![xmppStream isDisconnected]) return YES;

    [xmppStream setMyJID:[XMPPJID jidWithString:@"xxxx@xxxx"]];
    password = myPassword;

    NSError *error = nil;
    if (![xmppStream oldSchoolSecureConnect :&error])
    {
        //do something

        return NO;
    }

    return YES;
}

- (void)disconnect
{
        [self goOffline];
        [xmppStream disconnectAfterSending];
}

====================xmppstream delegate=======================

- (void)xmppStreamDidConnect:(XMPPStream *)sender
{
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);

    isXmppConnected = YES;

    NSError *error = nil;

    if (![[self xmppStream] authenticateWithPassword:password error:&error])
    {
        DDLogError(@"Error authenticating: %@", error);
    }
}

- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
{
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);

    [self goOnline];
}

- (void)xmppStreamDidDisconnect:(XMPPStream *)sender withError:(NSError *)error
{
    DDLogVerbose(@"%@: %@, error=[%@]", THIS_FILE, THIS_METHOD, error);

    if (!isXmppConnected)
    {
        DDLogError(@"Unable to connect to server. Check xmppStream.hostName");
    }
}

Could anyone help me to solve this problem? Thanks in advanced.

1. Separated XMPPStream internal Extension into the XMPPStreamInternal.h, which could be called from XMPPFeature;
2. Moved asyncSocket write/read data into a wrapper method -[XMPPStream write/readData ...], in which a registeredStreamPreprocessor could do preprocess (eg, XMPPCompression could deflate / inflate data);
3. Added XMPPFeature into calling procedure for XMPPStream;
4. Added XMPPCompression feature, which applies to XEP-0138 Stream Compression
5. Added XMPPCompression support into DesktopXMPP and iPhoneXMPP projects

Tested on OpenFire 3.8.2 and ejabbared 2.1.13

I accidently removed the branch and it caused this pull request closed. please add new comment to #563

After a period of inactivity, the stream disconnects with the following error:

Error Domain=GCDAsyncSocketErrorDomain Code=7 "Socket closed by remote peer" UserInfo=0x7ff222d0ce90 {NSLocalizedDescription=Socket closed by remote peer}, {
    NSLocalizedDescription = "Socket closed by remote peer";
}

The XMPPReconnect module reconnects to the server, but it goes into an infinite loop of periodically disconnecting (with the above error) and reconnecting, and even after reconnecting it doesn't receive any more data from the server until the stream is explicitly disconnected and connected again. I found some old discussion on this issue but wasn't sure if it was still relevant:

https://groups.google.com/forum/#!msg/xmppframework/6RZY3fN73_w/nv8fEGgJiQUJ

Thanks.

What is done:

• Basic acking scenario - acks and error handling
• Resumption
• XMPPStreamManagement module (but most logic done in XMPPStream.m, is it possible to move something in extension module?)
• XMPPRoster module modified not to reset roster on disconnect when stream management enabled
• Session data (Session ID and packet counters) saved and restored from NSUserDefaults (Will it make problems with multiple XMPPStreams application?)

TODO:

• Efficient acking scenario

Hi,

-I'm using XMPPFramework for chat messaging on IOS.

-I have problem when application waking more than 15 times in 300 seconds when iphone is locked.

-The application can only run on the background only if the iphone is not locked.

-Base on the log I found this message: ioq_select Attempting to replace UDP socket 9 ioq_select UDP has been replaced successfully!

-It seems that iphone reset the connection opened by XMPPFramework. -Does XMPPFramework support application running on the background while iphone is locked?

Appreciate if anyone can help on this.

Regards,

In iOS 9 all worked fine, after updating to iOS10, account becomes offline after the lock screen on iPhone.

self.xmppStream.enableBackgroundingOnSocket = YES;

I have tried to authenticate on secured openfire server from iOS using XMPP. It's connected successfully, but it did not get authenticate and i have received following error :

Error Domain=XMPPStreamErrorDomain Code=4 "No suitable authentication method found" UserInfo=0x79726370 {NSLocalizedDescription=No suitable authentication method found}

Is there any solution for it?

hello, XMPPFramework runs iOS16, crashes on Xcode14 device, the error is like a screenshot, please help to update and solve it, thank you very much, XMPPFramework is great！

Hi team, we are facing a crash when we upgraded to Xcode 14 and iOS 16 when we call the connection method

[xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]

it leads straight to the cocoa async socket dependency and crashes every time, attempted to make the connection.

we check with the latest version

• XMPPFramework/default (4.0.0):
  • CocoaAsyncSocket (~> 7.6)

but we're still getting the same crash.

Please provide us with your support, thanks.

We are using Openfire as our backend server and enabled with 5223 port for secure communication, What are the steps to enable 5223 communication ?

Thanks

Hi,

I can see multiple crashes in my organizer window for the XMPPStreamManagement.m class after enabling stream management. They aren't reproducible for me but these have been reported by different app users as well. I'm attaching the logs for the stack trace below:

In my Swift app i'm trying to connect with my server but in xmppStreamDidStartNegotiation i receive this error: "Document is empty". I think it's a connection problem but with this error description i can't suppose what is wrong.

Can you help me and give me any clue?

if i create one group and add members using inviteUser and add editPrivileges as a Member.

My question is I create one group and add members without member consent? @vitalyster
