AvAudioSession won't work in iOS7?

Question

#import "SctreamAudioViewController.h"
#import <AVFoundation/AVFoundation.h>
#import "SecondViewController.h"

@interface SctreamAudioViewController ()
@property (nonatomic, strong) AVPlayer *player;
@end

@implementation SctreamAudioViewController

#define STREAM @"http://localhost/audio.mp3"

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayAndRecord withOptions:AVAudioSessionCategoryOptionDefaultToSpeaker error:nil];
[audioSession setActive:YES error:nil];
NSURL *url = [[NSURL alloc] initWithString:STREAM];
self.player = [[AVPlayer alloc] initWithURL:url];
}

- (IBAction)play:(id)sender {

[self.player play];
}

I do quite a lot of researches on the net and I think this should be the right way to play audio in background. However, it just doesn't work out. I have no idea where it goes wrong. Please help. Thanks.

Are you sure http://localhost is reachable? Are you running a http server? Did you configured and started it correctly? — Samet DEDE, Feb 26 '14 at 14:39

[[AVAudioSession sharedInstance] setActive:NO error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback withOptions:AVAudioSessionCategoryOptionMixWithOthers error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];

if you want to play audio when app is in the background, you should use category Playback instead of playAndRecord. Also, you need to check Audio and airPlay in project-> target-> Capabilities-> backgroundMode

Look up UIBackgroundModes. You need to tell the system that your app is going to play sound in the background.

By how? You mean add "App plays audio" under "required background modes" in this plist? – Newbie Dec 04 '13 at 03:58

#define STREAM @"http://"

I believe http is not right in your #define. Try giving it as

#define STREAM (@"file://")
