I am implementing a XMPP client for my iPhone App, I ahve completed all the things in (Chatting with other users , showing presence of other users , etc.)
But the one thing for which I am stuck is that , I am unable to get the new user registered from my App. I am using following snippet,
if ([appDelegate.xmppStream supportsInBandRegistration])
[appDelegate.xmppStream registerWithPassword:txt_Password.text error:nil];
But for this, supportsInBandRegistration method always returns NO and the registerWithPassword: method is never called.
Please provide some help regarding the same.
What server are you using? Some servers support in-band registration even thought they don't send the correct stream:feature according to XEP-0077. Most of them should give the feature in the disco results however.
In other words, try commenting out your if ([appDelegate.xmppStream supportsInBandRegistration]) and see if it works. If so, you'll need to complain either to your library developer or to your server developer or both.

I am new to the whole creation-process of Google Actions.
I created an Action with the new Action Console.
It has an fulfillment endpoint to my server (as example: www.mypage.com/api).
For testing purposes it has no authentification, so it generates a public API response.
Said API generates a simple JSON response based on a send event handler.
In short: Action onEnter sends handler to API, API queries SQL database and sends the response back to my Google Action that then "speaks" the SQL result.
The result with the Actions Console Simulator is:
Testing with "Smart Display device: everything works.
Testing with "Speaker (e.g. Google Home): everything works.
Testing with "Phone": main intent is invoked and text is shown but does not get spoken.
So i tested the command "Hey Google, talk to the unicorn app" directly on my smartphone.
Here **everything works fine ** as said smartphone has the same e-mail like the one on my Action Console account: it recognizes the main invocation command and when i ask by voice to get the data, the data is received from my server and spoken.
So something is wrong with the "Phone" device in the simulator. This has been confirmed by me from other users saying that they often have trouble with the simulator function correctly.
I then deployed my Action.
It was reviewed and approved.
A few seconds later i received an auto-email saying that there were too many errors with my app, asking me to check its health status. I did so and in the Health tab, i can see that it has an error but it does not show me what the error is.
THEN I CONTACTED A ACTIONS-ON-GOOGLE EXPERT
They helped me a lot into the right direction but could not go deeper into the problem as my connection (the endpoint API) is outside of their servers.
So i ended with their tip on checking the Google Cloud Logging Console.
As said Logging Console is also new for me, i learned on how to query my results but:
How can i query for the so called "is_health_check" flag?
I am asking this because the Google Expert recommended me to search for said flag but i do not know on how to query it.
Sorry for this ultra-long entry but i am trying to be as transparent to you as possible, as i have been trying this out for several days now.
Thanks in advance for your time, ppl!
So the error is simple once that you know how Google handles the external webhooks. Thanks to the help of 2 Actions-On-Google Experts i was informed that Google pings your external Webhook from time to time.
As soon as they get an error as result from said ping, the Action will be deactivated from the Assistant until a new ping response sends that everything is fine again.
My problem was that after deploying the action and while it was under reviews, i continued to work on the code on my server. While coding, the Google server pinged and received an error code.
My fault, but at least i learned the thing about pinging your action!
I'm developing my first iPhone app to make what is effectively an app version of a fantasy league I created for work colleagues.
I am using Parse for the backend of the app. I only want people to be able to register with their work email address ie only if their e-mail address is _#mycompany.com
I'm sure this would be quite easy to someone who knew what htey were doing but I'm kind of new to this so any advice would be much appreciated.
Thanks
You could do this in a number of ways. The easiest way would be to have the validation happen on-device - just check the e-mail address the user has put into the app, and only allow the registration to happen if it matches the domain you want to limit it to.
However, although this is very easy it's also open to abuse and it's not very flexible (if you want to add additional domains, you have to update the app).
Fortunately, Parse offers cloud code, which lets you validate data server-side. Cloud code is written in JavaScript, and you then upload it to Parse. There is full documentation on Parse's website, including examples for validating data.
Am trying to integrate Apple Push Notification in my app. I have studied the Apple Document and other tutorials for my understanding. But, still i have a doubt to create a server and store all Apple Push Notification devicetokens in the database. Am not going to work on Server side but, i need to explain the approach to my client. I need to understand to create a APNS server provider and save all the apple push notification device tokens and retrieve all devicetoken and retrieve a single devicetoken to send notificaions. Can you please suggest me any sample code to save all apn devicetokens and retrieve from the server? I suggest my client to create a server in C#.net platform is this correct? Thanks in advance.
Essentially, you just need to decide on a way for your app to let your servers know the device tokens. So, there are many ways to achieve this.
If your server side already involves a website, the easiest way would be to use HTTPS to do a POST request from your app. Then, the server-side code can be written as if it is handling form request from browsers. I can't really give you sample code since I don't know any C#, but this should be familiar to any web developer.
I've been trying to integrate Facebook Credit purchases into my app, but any call to the pay dialog results in the error message "The application you are using is not responding." To eliminate any application specific problems, I've downloaded the Credits API Example and am just trying to get that to work -- it results in the same error message.
I've been trying for a couple of days to pinpoint this error message, but with no luck. Here's what I know so far:
Clicking the "Pay with Facebook" button results in error code 1383008, but there's no error_message being displayed.
I'm running Apache 2.2 on Windows 7. As far as I can tell, Apache is configured to allow requests from any source.
The canvas page is configured to point at http://localhost:8080/facebook.../ while the callback page is configured to point at http://localhost:8080/facebook.../callback.php. However, I have verified that the callback page is not being accessed.
I'm not sure how to verify whether or not Facebook is receiving my data correctly or if it's passing anything back. Any help in this regard would also be appreciated!
Credits attempts to make a callback to a web accessible url (or IP). If Facebook's spider cannot fetch the information from the callback script, then it will continue to return errors, since Facebook expects you to send information like the cost, name, image, custom parameters in order to process the payment.
Have a look at the creating a callback section of the docs:
http://developers.facebook.com/docs/creditsapi/
Adding to Fancis' answer, what you can do is setup a hole in your firewall and connect it to a dynamic dns service such as http://dyn.com/. Then you will be able to test your credits code.
I have a receipt of a recorded transaction stored by the application when the transaction was done and I would like to ask apple's servers if this receipt is valid.
Is there a way to do this without using an external server?

Perhaps it's just me, but it seems like you are asking to contact a server without contacting a server, which is quite impossible I'm afraid.
As far as I know, there are few json service provided by Apple:
One for the In App sandbox (before the submission):
https://sandbox.itunes.apple.com/verifyReceipt
One for the App Store version:
https://buy.itunes.apple.com/verifyReceipt
You can call them sending your receipt:
{
"receipt-data" : "(actual receipt bytes here)"
}
And it returns the answer:
{
"status" : 0,
"receipt" : { ... }
}
I assume you can make a direct call to the service within your iPhone app OR you can call your own server script that work as a proxy to the Apple service. It depends on your app logic. If you need to check the receipt on your server (IE. to authorize a download) you should call your server script otherwise you can verify the receipt directly from the app.
Doc reference:
http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StoreKitGuide/VerifyingStoreReceipts/VerifyingStoreReceipts.html
this case is solved. It is possible to do that using just the iphone.
To clarify:
Only the Apple Server can give information about the validity of a
transaction receipt. Indeed you have to contact this server even just
to find out if a product is still active (or if the user has
cancelled the subscription).
On the web, you get the impression that
it is not at all, or at least not in any safe way, possible to
contact this Apple Server simply via HTTP-POST out of your app.
Everybody seems to be convinced you need to have a web server which
is contacted from your app, and that you should only contact Apple's
server from your web server.
Apple, however, even provides implementation code (I wish I had found that earlier) on how to contact the verification server safely without another web server in between:
http://developer.apple.com/library/ios/#releasenotes/StoreKit/IAP_ReceiptValidation/_index.html
This implementation is similar to what lomanf mentioned, just in more detail and with all the security needed to make it work even with iOS 5.x.
So the answer is most definitely: Yes.
