Question

I have to task to develop an application which plays sound after user blow candles and than the sound should play. For blowing candle I have used AVAudioRecorder that catch user blow and than its starts animation of stopped candles and than it should start to play the song but its not playing the song. I have stored song locally.(in my application)

for AVAudioRecorder

    NSURL *url1 = [NSURL fileURLWithPath:@"/dev/null"];

    NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:
        [NSNumber numberWithFloat: 44100.0], AVSampleRateKey,
        [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey,
        [NSNumber numberWithInt: 1], AVNumberOfChannelsKey,
        [NSNumber numberWithInt: AVAudioQualityMax],  AVEncoderAudioQualityKey,
        nil];
    NSError *error1;

    recorder = [[AVAudioRecorder alloc] initWithURL:url1 settings:settings error:&error1];

animation images starts and after that song should be play.

imageView1.animationImages= [NSArray arrayWithObjects:
    [UIImage imageNamed:@"can6.png"],
    [UIImage imageNamed:@"can7.png"],
    [UIImage imageNamed:@"can8.png"],
    [UIImage imageNamed:@"can9.png"],
    [UIImage imageNamed:@"can10.png"],nil];
    [imageView1 setAnimationRepeatCount:1];
    imageView1.animationDuration=0.7;
    [imageView1 startAnimating];
    [recorder stop];
    player = [[AVAudioPlayer alloc] 
              initWithContentsOfURL:[NSURL fileURLWithPath:
             [[NSBundle mainBundle] pathForResource:xyz song ofType:nil]]
             error:nil];
    NSLog(@"music play-%@",xyz song);
    [player prepareToPlay];
    [player play];

All codes are working properly only sound is not playing.
I get candle stop animation starts but I can’t here the song. Although the above sound play code works in another view perfectly and its plays the song but it’s not playing the song here. Please help me.

Answer 1

Check that the result of [[NSBundle mainBundle] pathForResource:xyz song ofType:nil] is not nil. I think the problem might be passing nil for type. For example, if your song is HappyBirthday.mp3, you should call

[[NSBundle mainBundle] pathForResource:@"HappyBirthday" ofType:@"mp3"];
