Currently i am working on app in which i want to play continues sound when app receives push notification. as i know apple allow to play custom sound of length of 30 sec here is link..
but in well known app it plays continues sound in driver side when app is in back ground and driver receives order.
and another issue is of when my app is in back ground and receives push notification Rather clicking on notification if i open app by pressing app icon it does not show me data of push. it is not possible to load data when press on app icon here is link
iOS Push notification issue
but same thing is done in well known app
With iOS 7+, use application:didReceiveRemoteNotification:fetchCompletionHandler:, which is called even if your app is in the background. iOS will even launch your app in the background if it's not already running, but if the user force quits the app, it will not be re-launched. If you enable the remote-notification background mode, you can run app code when the notification arrives. If you include the audio background mode, you could initiate a sound that continues to play while app is in background.
For second question, typically, your app should query a server for updates if it's launched directly. However, you could leverage a remote notification as above, which you'd get in most cases (except if the app were force quit).

I'm working on an app in which, upon receiving a push notification while in the background, should play a continuous sound until the app is opened.
Also, if the app is opened by clicking on the app icon, it should load push data.
How can I do this?
My application currently uses the application:didReceiveRemoteNotification:fetchCompletionHandler and application:didFinishLaunchingWithOptions: delegate methods to handle background remote notifications. Intermittently, a push notification will appear, and I will not receive a log that says that it has called either of my application delegate methods. I have tested for suspended, active, background, and suspended states, and they all seem to be working correctly. About 1 in every 30 pushes I get a 'dead' push notification.
****NOTE: This case only happens when I do NOT enter by touching the push notification, and happens unpredictably.**
The error came from an iOS 8 "feature" in Apple's docs. If an iPhone has less than great cellular or wifi signal, low battery, or is not plugged into a charger, the phone will receive the notification on the lock screen, but will not launch the app into a suspended state. Therefore, background events such as application:didReceiveRemoteNotification:fetchCompletionHandler will not be fired IF you do not enter directly into the application by swiping the notification itself.
This was offset in testing by the fact that the device was always plugged into my development machine during debugging with a strong wifi signal, so I would never be put into a bad state.
This is extremely specific, but crucial if your app relies heavily on push notifications for background functionality.
In my application iam using UILocalNotifications, and for that notification iam setting 30 sec audio file.
Notification fired if device is UnLock state and my app is in background mode then if i click on notification bar then my app is open and notification sound is stopping. This scanario is fine.
Notification fired if device is locke state and my app is in background mode then if i drag the notification then my app is open and notification sound is not stopping. In this scanario notification sound is continuesly playing upto 30 sec.
I need to stop the notification sound when app is open.
Please help me for implementing this functionality.
Thanks in advance.
You can't, since the sound is played by iOS and not your app. Thus you have no control over it.
I am detecting for iBeacon in background. When my device comes in a particular region application should comes to foreground.
It cannot be done without user interaction. The only option is you can generate a push notification to tell the user to bring the application to foreground.
This is from the Apple documentation about this issue:
When the operating system delivers push notification (iOS or OS X)
and the target application is not running in the foreground, it
presents the notification (alert, icon badge number, sound). If there
is a notification alert and the user taps or clicks the action button
(or moves the action slider), the application launches and calls a
method to pass in the local-notification object or remote-notification
payload. If the application is running in the foreground when the
notification is delivered, the application delegate receives a local
or push notification.
To answer to some comments about WhatsApp, with it, when you receive a classic vocal call, IOS use CallKit to display your call and wake up your phone, but it's not inside app. I try to make a video call with WhatsApp, and in this case, there is a notification. Press notification open app and answer to the call.
Conclusion : It's impossible to wake up app from background to foreground in IOS, but it's not really a problem because you can use notification to display what you want and get the user to your app after a touch on your notification. All of iPhone users are familiar with this kind of interaction, it's better to deal with it.
I implemented Push notifications in iOS. I want my application to play a music (about 15sec) when I send a push message. I am currently getting the push message, and the music is being played only if the app is in the foreground.
If the app is in the background, it shows up a notification, and when i tap it, it then plays the music.
But how do I get the functionality of automatically playing the music? I think this can be done because, in iOS, Audio apps can run in the background. So I just want the music to be played when the app goes to background, and it receives a push.
Can anyone help me with this please?
Thanks,

Yes, there are two ways to do this.
The traditional way before iOS 7 is to register for audio playing background mode and play a silent sound forever, this will keep your app running in the background for a long time until the user kills it, or it is killed due to low memory.
This way has many drawbacks, the user must launch your app once so that you can start playing the sound and every time the iPhone is shut off, the user need to relaunch your app when he turn on the iPhone.
Also this will consume a lot of battery. 20%-30% a day for an iPhone 5.
The new way after iOS 7.0 is to exploit background fetch and remote notification, you can play your sound while performing a background fetch, which has a 30 seconds running time. Also you can trigger a background fetch with a push notification.
