tvOS app doesn't play audio file

Question

I have a tvOS app which attempts to play an audio file like this:

#import "NameViewController.h"
#import <AVFoundation/AVFoundation.h>

@interface NameViewController ()

@end

@implementation NameViewController
- (void)viewDidLoad {
    [super viewDidLoad];

    NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"intro" ofType:@"mp3"];
    NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
    AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL fileTypeHint:AVFileTypeMPEGLayer3 error:nil];
    player.numberOfLoops = -1; //infinite

    [player play];


}

If I put a breakpoint after [player play]; it starts playing for a few seconds. If I don't have the breakpoint, no audio ever plays.

What am I doing wrong?

Answer 1

This worked by calling play in viewWillAppear:

#import "NameViewController.h"
#import <AVFoundation/AVFoundation.h>

@interface NameViewController ()
@property (strong, nonatomic) AVAudioPlayer *player;
@end

@implementation NameViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    [self createAndStartAudioPlayer];


}

- (void) viewWillAppear:(BOOL)animated{

    [self.player play];
}

- (void) createAndStartAudioPlayer {
    NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"intro" ofType:@"mp3"];
    NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
    self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL fileTypeHint:AVFileTypeMPEGLayer3 error:nil];
    self.player.numberOfLoops = -1; //infinite


}
