AVAudioPlayer does not play when app goes to background - ios

Question

I am trying out the AVFoundationFramework.
Presently I am able to run the AVAudioPlayer in the foreground.
When the app goes to the background, the AVAudioPlayer does not continue to play.
The exact steps of implementation are:
Adding Background Tasks to the .plist
Setting up AVAudioPlayer
self.objAVAudioPlayer = [[AVAudioPlayer alloc]initWithData:mp3Data error:&error];
self.objAVAudioPlayer.delegate = self;
Setting up AVAudioSession
if([self.objAVAudioPlayer prepareToPlay])
{
AVAudioSession *objAVAudioSession = [AVAudioSession sharedInstance];
[objAVAudioSession setCategory:AVAudioSessionCategoryPlayback error:&error];
[objAVAudioSession setActive:YES
error:nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[self.objAVAudioPlayer play];
}
When the app is resumed, it starts from the exact same place where it resigned.
The base SDK is iOS 7.0.
Any idea as to what I am missing? Any help will be appreciated.

For playing audio in background mode you should set up AVAudioSession and add this code
UIBackgroundTaskIdentifier backgroundTask = [application beginBackgroundTaskWithExpirationHandler:^{
[application endBackgroundTask:backgroundTask]; //Tell the system that we are done with the tasks
backgroundTask = UIBackgroundTaskInvalid; //Set the task to be invalid
}];
into your AppDelegate.m class in method
- (void)applicationDidEnterBackground:(UIApplication *)application {
//Some code
}
