Xmppstream delegate methods not getting in my custom class

Question

I started with xmppframework recently, but I am stuck in a problem. I can connect to my server on my local network, but the xmppstreamdelegate methods do not receive a call in my user class, but work fine on the appdelegate class. Can anyone help me on this. Or did the delegate only support the appdelegate class?

Title:

@interface XmppClass : NSObject<XMPPStreamDelegate>{ XMPPStream *xmppStream; Login * loginDetail; BOOL allowSelfSignedCertificates; BOOL allowSSLHostNameMismatch; } @property (nonatomic, strong, readonly) XMPPStream *xmppStream; @property (nonatomic, strong) Login *loginDetail; - (id)initWithLogin:(Login *) loginrefernce; - (BOOL)connect; - (void)disconnect; - (void)setupStream; @end 

Implementation:

 @implementation XmppClass @synthesize xmppStream; @synthesize loginDetail; - (id)initWithLogin:(Login *) loginrefernce { self = [super init]; if (self) { self.loginDetail=loginrefernce; [DDLog addLogger:[DDTTYLogger sharedInstance]]; [self setupStream]; [self connect]; } return self; } - (void)setupStream { NSAssert(xmppStream == nil, @"Method setupStream invoked multiple times"); // Setup xmpp stream // // The XMPPStream is the base class for all activity. // Everything else plugs into the xmppStream, such as modules/extensions and delegates. xmppStream = [[XMPPStream alloc] init]; #if !TARGET_IPHONE_SIMULATOR { // Want xmpp to run in the background? // // PS - The simulator doesn't support backgrounding yet. // When you try to set the associated property on the simulator, it simply fails. // And when you background an app on the simulator, // it just queues network traffic til the app is foregrounded again. // We are patiently waiting for a fix from Apple. // If you do enableBackgroundingOnSocket on the simulator, // you will simply see an error message from the xmpp stack when it fails to set the property. xmppStream.enableBackgroundingOnSocket = YES; } #endif NSLog(@"setup stream"); [xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()]; [xmppStream setHostName:@"10.68.202.123"]; //[xmppStream setHostPort:8070]; allowSelfSignedCertificates = NO; allowSSLHostNameMismatch = NO; // You may need to alter these settings depending on the server you're connecting to } - (BOOL)connect { NSLog(@"connect"); if (![xmppStream isDisconnected]) { return YES; } // // If you don't want to use the Settings view to set the JID, // uncomment the section below to hard code a JID and password. // // myJID = @" [e-mail] /xmppframework"; // myPassword = @""; if (self.loginDetail.emailId == nil || self.loginDetail.password == nil) { return NO; } [xmppStream setMyJID:[XMPPJID jidWithString:[self.loginDetail.emailId stringByAppendingString:@"/pc"]]]; NSError *error = nil; if (![xmppStream connect:&error]) { NSLog(@"Error connecting: %@", error); return NO; } return YES; } - (void)disconnect { [xmppStream disconnect]; } - (void)xmppStream:(XMPPStream *)sender socketDidConnect:(GCDAsyncSocket *)socket { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); } - (void)xmppStream:(XMPPStream *)sender willSecureWithSettings:(NSMutableDictionary *)settings { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); NSLog(@"some security thing"); if (allowSelfSignedCertificates) { [settings setObject:[NSNumber numberWithBool:YES] forKey:(NSString *)kCFStreamSSLAllowsAnyRoot]; } if (allowSSLHostNameMismatch) { [settings setObject:[NSNull null] forKey:(NSString *)kCFStreamSSLPeerName]; } else { // Google does things incorrectly (does not conform to RFC). // Because so many people ask questions about this (assume xmpp framework is broken), // I've explicitly added code that shows how other xmpp clients "do the right thing" // when connecting to a google server (gmail, or google apps for domains). NSString *expectedCertName = nil; NSString *serverDomain = xmppStream.hostName; NSString *virtualDomain = [xmppStream.myJID domain]; if ([serverDomain isEqualToString:@"talk.google.com"]) { if ([virtualDomain isEqualToString:@"gmail.com"]) { expectedCertName = virtualDomain; } else { expectedCertName = serverDomain; } } else if (serverDomain == nil) { expectedCertName = virtualDomain; } else { expectedCertName = serverDomain; } if (expectedCertName) { [settings setObject:expectedCertName forKey:(NSString *)kCFStreamSSLPeerName]; } } 

}

 - (void)xmppStreamDidSecure:(XMPPStream *)sender { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); } - (void)xmppStreamDidConnect:(XMPPStream *)sender { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); NSLog(@"connected"); NSError *error = nil; if (![[self xmppStream] authenticateWithPassword:self.loginDetail.password error:&error]) { DDLogError(@"Error authenticating: %@", error); } } - (void)xmppStreamDidAuthenticate:(XMPPStream *)sender { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); NSLog(@"authenticated"); } - (void)xmppStream:(XMPPStream *)sender didNotAuthenticate:(NSXMLElement *)error { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); NSLog(@"did not authenticate"); } - (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); return NO; } - (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); // A simple example of inbound message handling. } - (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence { DDLogVerbose(@"%@: %@ - %@", THIS_FILE, THIS_METHOD, [presence fromStr]); } - (void)xmppStream:(XMPPStream *)sender didReceiveError:(id)error { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); } - (void)xmppStreamDidDisconnect:(XMPPStream *)sender withError:(NSError *)error { DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD); NSLog(@"%@",error); } @end 

Answer 1

Most likely, the problem is that your class instance, which is the delegate for your XMPPStream, is freed before the delegate method is called. Make it more persistent by making this class a property variable or an instance of another class, or using dispatch_once. For example,

Edit

 YourClass *instance = [[YourClass alloc] init]; instance.xmppStream = .... 

 @property(nonatomic, strong) YourClass *instance; self.instance = [[YourClass alloc] init]; self.instance.xmppStream = .... 

Here YourClass contains an XMPPStream and is a delegate for it.

I wrote a great blog post on this issue. This is a fairly common situation. http://blog.alwawee.com/2013/07/31/on-xmppframework-delegate-method-not-being-called/

Answer 2

you can use multicast for example

 [[self appDelegate].xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()]; 

Answer 3

I had the same problem ... it helped me. Hope this works for you, just make the following changes to your code.

 Static XmppClass *selfRef = nil; @implementation XmppClass @synthesize xmppStream; - (void)setupStream { // Setup xmpp stream selfRef = [[XmppClass alloc] init]; xmppStream = [[XMPPStream alloc] init]; [xmppStream addDelegate:selfRef delegateQueue:dispatch_get_main_queue()];
