Push notification problem - iphone

Im developing an iphone app with push notification service, the problem that when i sent an non English language notification the notification dose not appear on iphone screen but the Badge Number appear on the app icon and the sound for push notification played, on the other hand when i sent an English notification every thing going good.
i sent the notification via php service and the php can understand the non English language so where are the problem ?!!!
any help :)

I can confirm that non-English characters can be sent via APNS. I would focus on the php framework you are using.
Maybe this SO post can help: Push Notification in non english languages. Essentially, the payload length could be calculated incorrectly.

https://www.elecfreaks.com/store/blog/how-to-send-temperature-threshold-value-alarm-email-via-ifttt.html
I made some relook and found out that problem was on my side. Meaning the naming conversion was on the lower case instead of Upper Case. E.g temp_critical(name of my webhook and reactapp) instead of Temp_Critical(name of my webhook and email/reactapp, thinghttp). I was able to get an notification if my temperature was critical.

How does WhatsApp know if the user gets the push notification even if the app is runnng in the background and is not open?

I have already asked related question:
any option to know if apple app get the push notification?
And I got an answer that it is not possible to know if push notification comes to the iPhone when application is in the background and the user does not have it opened...
But I found something interesting:
I take 2 iPhones with WhatsApp. I open, in the first iPhone, WhatsApp and exit it (the WhatsApp is in the background now), then with the second iPhone, I send WhatsApp massage to the first iPhone.
When the push notification of WhatsApp reaches first iPhone I can see two "V" (symbols) near to the message (and I don't open the Push notification). After this I close the Internet & 3G in the first iPhone and again send WhatsApp message with the second iPhone to the first one. - and I can see only one "V" near to the massage (not read - not get push notification).
Now after re-enabling the Internet on the first iPhone and after I get the push notification I can see two "V" (again - I don't open the push notification).
How does it work? How does WhatsApp know whether the iPhone gets the push notification or not while the WhatsApp works in the background?
Let us call the iPhone with WhatsApp application closed - the receiver and the other iPhone you send messages with - the sender, and let us use generic term application instead of WhatsApp
The application at the sender is not able to learn that push notification has reached the receiver. It is by the nature of push notifications.
However, the sender is possible to send another - not a push notification, but prioprietary protocol - message to the application at the receiver which it (the receiver) is welcome to acknowledge to the sender in any application-specific way it wants.
So, I would guess (I don't know - I'm not affiliated with WhatsApp in anyway) that the double-v icon you get is when application message reaches the application at the receiver - and has nothing to do with push notification.
What you mean is just the basics of push-technology :
The whatsapp software runs in the background listening on a specific port
for incoming messages. It does this continuously.
BTW :
One V = message delivered from your mobile to the whatsapp server
Two V's = message pushed from whatsapp server to recipient mobile
Blue V's indicate message has been read
Whatsapp doesn't show if the person reads the message or not. It just informs when the message has been sent to the whatsapp servers(one V) and when it has been sent the person phone (2 V's). The double does not mean the message was read it just means that whatsapp connected to the phone and was able to pass on the message.
After receiving a push notification the receiver can download data from a URL that you include in the payload of your push notification. By requesting that URL the server knows that the receiver received the push notification and can pass this status on to your sender application.
Like so:
Add a specific URL in your push notification payload
Implement the application:didReceiveRemoteNotification:fetchCompletionHandler: method in your app delegate and in that method call the URL from the payload.
Implement a logic on your server that recognizes the URL call as a received notification
Let your sender application continuously get the current notification status from the server.
The above posters are all correct. Just to add one more thing. If Whatsapp has recently been closed, it is still running in the background and can still receive the message (hence the return receipt). However, after the app is left unused for a while (or other apps have higher priority) Whatsapp is terminated, then it will no longer receive incoming messages and will not return receipt.
Of course the observant person would notice a small lag between opening the app and the new messages being displayed which seems to suggest the messages are not downloaded in the background but only downloaded upon opening the app. So why does it return receipt while running in the background?

Send SMS programmatically, without the SMS composer window

Until yesterday I thought that it was not possible to send background SMS without using the IOS SMS interface (Which many people here assure also). However, today I downloaded a new app called SmartSender, which schedules your SMS and then sends it automatically.
I tested it and the SMS is not actually sent on background, but a local notification appears and when you click on it to bring app to foreground, the SMS is sent automatically.
How could this be achieved?
Maybe Apple approved the app because the interface is very clear on what you are doing and what you are sending, but how can you send SMS without showing the interface?
Update: The scheduled SMS appear on my phone Messages app as sent, so I don't think that they are using another service to send SMS, also the receiver phone is indicated that the SMS was sent from my phone.
Update 2: OK I'm using and watching the app doing this, so IT IS POSSIBLE without showing the default interface, I'm not asking whether this can be done or not. I am using it with all internet connections turned OFF, and the message is sent from MY PHONE so it appears on the MESSAGES APP. So the app is not using any third party service.
Update 3: I will accept my own answer, in fact it is not possible; however it was when the question was answered. The App in question has now specified in its description that it won't work in iOS 6, so I think Apple patched some bug that could be exploited to achieve this functionality.
Having tried the app, I can verify that it does send SMS programmatically, without showing the SMS interface. And it clearly doesn't happen through a third-party service, since the message gets sent as an iMessage when possible.
It's also clear from all the other answers that there aren't any public APIs for sending SMS programmatically, so the developer must have used a private API and yet somehow snuck this app through the approval process.
Specifically, it seems he used the CoreTelephony API. This post on SO describes the procedure. Apparently you'll also need to get your hands on the CoreTelephony header files somewhere.
I've been looking into the SMS send/receive limitation on iOS for a few days, using iOS 6 and XCode 4.5 (latest as of writing). I was curious about this SmartSender application so I purchased it.
I don't know if it's because I only tried it on iOS 6, but I get the standard message controller (MFMessageComposeViewController) to send messages. I have tried delayed send - I get the message controller at prescribed time and have to manually click on Send. I have tried immediate send - that pops up the controller and I also have to manually click on Send. If I click on Cancel, the app actually loops me back into the message controller (I can't cancel unless I kill the app!)
So true, this allows entering messages from a custom UI, but then the message itself is copied into the MFMessageComposeViewController and that is what sends the SMS. So App Store approved, but nothing like what we're all looking for!
You can not send SMS programmatically in background, you can use following third party API to send the text message (SMS).

http://www.nexmo.com/

I would suggest nexmo, its easy to use and support international messages also.
In fact it is not possible; however it was when the question was answered.
The App in question has now specified in its description that it won't work under IOS 6, so I think apple patched some bug that could be exploited to achieve this functionality.
You can use:
[[UIApplication sharedApplication] openURL: #"sms:+3912345678"];
it doesn't work on simulator... and you cannot send programmatically sms!
Tested on iOS < 6.
There is no way to send SMS programmatically. You may want to investigate a 3rd party service service for sending SMS like Twilio.
