I had solved this question by referring iOS Application Background tasks
and make some changes in .plist
file of our application..
Update
write this code in your controller’s view did load method like this
- (void)viewDidLoad
{
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"in-the-storm" ofType:@"mp3"]];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[audioPlayer play];
[super viewDidLoad];
}
