Unable to connect XMPPFramework to Openfire server in iOS - ios

I am working on an iOS chat app where user login to app. I've downloaded XMPPFramework from GitHub XMPPFramework. I am trying to connect XMPP framework with Openfire server by following this tutorial. Here is my code to connect XMPP to openfire.
- (BOOL)connect {
[self setupStream];
[xmppStream setHostName:#"192.168.1.5"];
[xmppStream setHostPort:5222];
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 isConnected])
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error"
message:[NSString stringWithFormat:#"Can't connect to server %#", [error localizedDescription]]
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alertView show];
return NO;
}
return YES;
}
The problem is when I run the app, it shows the alert can't connect to server. I have checked many questions on StackOverflow and tried googling but couldn't find any relevant solution. How to connect it to the Openfire serve? If I am doing anything wrong in my code please suggest me with a snippet of code or a tutorial to make this happen.

A host of possibilities.
Try adding break points at xmppStreamDidConnect and xmppStreamDidAuthenticate.
If xmppStreamDidConnect isn't reached, the connection is not established; you've to rectify your hostName.
If xmppStreamDidAuthenticate isn't reached, the user is not authenticated; you've to rectify your credentials i.e. username and/or password.
One common mistake is omitting of #domainname at the back of username i.e. username#domainname e.g. keithoys#openfireserver where domain name is openfireserver.

Hope this still relevant, if not, hopefully it will help others.
There are some issues with your code:
I don't see the call to connect, you should add something like this:
NSError *error = nil;
if (![_xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error connecting"
message:#"Msg"
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alertView show];
}
Most of the XMPP API is asynchronous.
You have to set the stream delegate in order to receive events.
Check out XMPPStreamDelegate and XMPPStream#addDelegate
If you don't want to go through the code yourself XMPPStream.h
, you can implement all methods of XMPPStreamDelegate and log the events. This will help you understand how the framework works.
Hope this helps, Yaron

How can manage openfire connection on 2G network?

I created messaging application like whatsApp and hike. Its working on 3G,4G and Wifi network. when user switch to 2G network my app connection is interrupted but whatsApp and hike working perfectly. I posting code where i manage app connection ::
#pragma mark - connect to the server
- (BOOL)connect {
if (!self.xmppStream) {
[self setupStream];
}
NSString *jabberID = [[NSUserDefaults standardUserDefaults] stringForKey:kUserName];
if (![self.xmppStream isDisconnected]) {
return YES;
}
if (jabberID == nil || kXMPPPassword == nil) {
return NO;
}
[self.xmppStream setMyJID:[XMPPJID jidWithString:jabberID]];
[self.xmppStream setHostName:kXMPPHost];
NSError *error = nil;
if (![self.xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&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];
NSLog(#"errorerrorerrorerrorerrorerror :- %#", error);
return NO;
}
return YES;}
- (void)connectThenSignIn {
if ([_xmppStream isConnecting]) { // Connection error, connection is being established
return ;
}
if ([_xmppStream isDisconnected]) { // If disconnected, a server connection is established
[self connect];
_goToRegisterAfterConnected = NO;
} else if ([_xmppStream isConnected]) {
[self doSignIn];
} }
Please suggest me best way to manage openfire connection on every network (2G, 3G, 4G and wifi).
Those applications are probably using push notifications to receive updates while on unreliable IP networks (like 2G). This allows them to appear online without maintaining a constant connection to a server.
This is difficult to accomplish with XMPP -- the protocol was written with the assumption that users only need to be reachable while they are connected to the server. Some XEP extensions have added partial workarounds, but the protocol as a whole is poorly suited to mobile clients. (This has been a well-known limitation since at least 2014.) You may want to consider alternatives.

How to Integrate payment using Authorize.Net for iOS

I have integrated authorize.net into my iOS application. I did steps in this tutorial
https://developer.authorize.net/integration/fifteenminutes/ios/
- (void) loginToGateway {
MobileDeviceLoginRequest *mobileDeviceLoginRequest =
[MobileDeviceLoginRequest mobileDeviceLoginRequest];
mobileDeviceLoginRequest.anetApiRequest.merchantAuthentication.name = <USERNAME>;
mobileDeviceLoginRequest.anetApiRequest.merchantAuthentication.password = <PASSWORD>;
mobileDeviceLoginRequest.anetApiRequest.merchantAuthentication.mobileDeviceId =
[[[UIDevice currentDevice] uniqueIdentifier]
stringByReplacingOccurrencesOfString:#"-" withString:#"_"];
AuthNet *an = [AuthNet getInstance];
[an setDelegate:self];
[an mobileDeviceLoginRequest: mobileDeviceLoginRequest];
}
But request responsive:
- (void) requestFailed:(AuthNetResponse *)response{
NSLog(#"ViewController : requestFailed - %#",response);
[_activityIndicator stopAnimating];
UIAlertView *infoAlertView = [[UIAlertView alloc] initWithTitle:#"Login Error" message:INFORMATION_MESSAGE delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[infoAlertView show];
}
What's to fill in here?
mobileDeviceLoginRequest.anetApiRequest.merchantAuthentication.name = <USERNAME>;
mobileDeviceLoginRequest.anetApiRequest.merchantAuthentication.password = <PASSWORD>;
The Name and Password are the Login ID and Password for a user created in the Merchant Interface. If you specified the test environment and are connecting to the sandbox, this would be the username and password you use to login to https://sandbox.authorize.net

Parse - Sign Up and Login at the same time

Using Parse (iOS framework), I am able to sign up and login successfully using two API.
When user log in, it will cache the user and so accessing "currentUser" will return appropriate object. But sign up API is not caching.
Is there any way that sign up itself will cache the user and avoid separate log in functionality?
It should automatically log you in as well. For example, if in your completion block in signUpInBackground, you have a segue to your main screen and in your main screen, it is supposed to show information related to the user, then it will because [PFUser currentUser] is set to the user that registered.
here is an example
[user signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:[[error userInfo] objectForKey:#"error"] message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:#"Ok", nil];
[alertView show];
// Bring the keyboard back up, because they'll probably need to change something.
[_usernameField becomeFirstResponder];
}
else{
// Success!
[self performSegueWithIdentifier:#"goToMain" sender:self];
}
}];

Authenticate Anonymously using XMPP framework in iOS

I want to connect to openfire server anonymously using xmpp framework in iOS. I can connect to open fire by providing the JID and PW. However when I tried to connect anonymously it says "The server doesn't support anonymous authentication".
I'm using a button in xib file. When its clicked below code executes:
- (IBAction)login:(id)sender {
[[self appDelegate]connect];
NSError *authenticationError = nil;
[self.xmppStream authenticateAnonymously:&authenticationError];
}
and below is the code for connect method:
- (BOOL)connect {
[self setupStream];
xmppStream.hostName = #"abc.xyz.com";
//xmppStream.hostName = #"Virtuals-MacBook-Pro.local ";
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 connectWithTimeout:XMPPStreamTimeoutNone error:&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;
}
Steps for anonymous authentication:
1- First of all connect the xmpp-stream, then authenticate anonymously.
[[self xmppStream] authenticateAnonymously:&error];
then you will be authenticated anonymously. but a very important thing. before authenticating, get the username and password of a registered user and connect to the xmpp-stream
The accepted answer is almost right but is mixing things (connection and authentication)
What you are facing is probably a server side configuration problem, if your server does not allow you to log in anonymously you cannot, period.
Anyway you can still try to connect anonymously and handle the fact that you are not allow, for that you need to:
1) Set your JabberID to anonymous#domain (were domain is your server domain)
[self.xmppStream setMyJID:[XMPPJID jidWithString:#"anonymous#domain"]];
2) With that in place you can connect to the server (you do not need a valid user as the accepted answer pointed out)
[self.xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]
3) Once you get response from the sever your XMPP delegate method didConnect will be called, in there you check if the server configuration supports anonymous authentication and if so try to authenticate anonymously
- (void)xmppStreamDidConnect:(XMPPStream*)sender
{
self.isXmppConnected = YES;
if ([self.xmppStream supportsAnonymousAuthentication]) {
NSError* error = nil;
//the server does support anonymous auth
[self.xmppStream authenticateAnonymously:&error];
}
else {
NSLog(#"The server does not support anonymous authentication");
}
}
4) You handle however you want the situations were the server does not support anonymous auth (maybe trie with a well know user or display a warning to the user) or you get an error authenticating (network issues)

When should I renew an ACAccount? Or, how to check if the credential is expired. (Facebook)

Recently I was assigned to survey how to use iOS framework ACAccount and Social to implement facebook post function. It is quite simple to gain access of the account configured in setting.
if(!_accountStore)
_accountStore = [[ACAccountStore alloc] init];
ACAccountType *facebookTypeAccount = [_accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
// Check if there is any faceboook account
NSArray *accounts = [_accountStore accountsWithAccountType:facebookTypeAccount];
if (![accounts count]) {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"alert" message:#"No facebook account configured in setting." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
return;
}
[_accountStore requestAccessToAccountsWithType:facebookTypeAccount
options:#{ACFacebookAppIdKey: #"FACEBOOK-APP-ID", ACFacebookPermissionsKey: #[#"email"]}
completion:^(BOOL granted, NSError *error) {
if(granted){
NSArray *accounts = [_accountStore accountsWithAccountType:facebookTypeAccount];
_facebookAccount = [accounts lastObject];
NSLog(#"Success");
}else{
// ouch
NSLog(#"Failed, Error: %#", error);
dispatch_async(dispatch_get_main_queue(), ^{
NSString *message = [NSString stringWithFormat:#"App access denied, please grant access in Setting->Facebook. Error message::%#", error];
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Alert" message:message delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
});
}
}];
Once the app gain access to facebook, it can post message by using SLComposeViewController:
- (IBAction)postButtonPressed:(id)sender {
if (!_facebookAccount) {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"alert" message:#"login first" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
return;
}
SLComposeViewController *fbController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result){
[fbController dismissViewControllerAnimated:YES completion:nil];
switch(result){
case SLComposeViewControllerResultCancelled:
default:
{
NSLog(#"Cancelled.....");
}
break;
case SLComposeViewControllerResultDone:
{
NSLog(#"Posted....");
}
break;
}};
[fbController setInitialText:#"Test message"];
[fbController setCompletionHandler:completionHandler];
[self presentViewController:fbController animated:YES completion:nil];
} else {
NSLog(#"no facebook setup");
}
Here comes my question. I found that there is a method in ACAccountStore which is used to renew expired credential of an ACAccount:
- (void)renewCredentialsForAccount:(ACAccount *)account completion:(ACAccountStoreCredentialRenewalHandler)completionHandler;
But I don't even know how to check whether the credential is expired so that I can renew it. Anyone got an idea about this?
Oh, by the way, we just want to use the native Social framework to do simple work such as post some message or picture. So, if not needed, we are not going to use the facebook SDK.
If you know anything about how to check the credential is valid or not, please leave a comment or submit an answer, thank you:)
Updates 2013.11.20 11:10 AM
I learn something from my experiments to this issue..
One is not able to get certain type of accounts from account store before he gains access to them, so I should not check account count before request for access.
Renew notification called when the app using ACAccount is in background after facebook account changed. Currently, I only saw changes of access right triggers the notification.
If the user changes password, the system will pop out an alert when the user attempt to post something, which ask the user to change password.
I think monitor notifications of account change is enough to handle the changes. I'll accept the first answer.
You should renew the user acc everytime it is out of sync. This may happen if the user has changed his password or when the acc session has expired.
Yo can know you are in that scenario using the following notification:
ACAccountStoreDidChangeNotification
I don't think there is active way , best is to write renew function and call
renewCredentialsForAccount of the framework
