I have manually uploaded mp3 files in PFFile object,

class: Songlist:

          1)songTitle(string)     2)song(PFFile)

I am using code below:

 - (void)viewDidLoad {
    [super viewDidLoad];
    isPlaying = NO;
     PFQuery *query = [PFQuery queryWithClassName:@"Songlist"];
    [query whereKey:@"songTitle" equalTo:@"Kamli"];
     NSLog(@"QUERY %@",query);

     PFObject *songObj= [query getFirstObject];
         NSLog(@"get Whole song file %@",[query getFirstObject]);

     PFFile *roomAudio = [songObj objectForKey:@"song"];

         NSLog(@"PFfile %@ :",roomAudio);

       NSURL url1 = [NSURL URLWithString:roomAudio.url]; NSData audioData = [NSData   dataWithContentsOfURL:url1];

          NSLog(@"Song  :%lul", audioData.length);

      self.player= [[AVAudioPlayer alloc] initWithData:audioData error:nil];

       self.player.numberOfLoops = -1;
       [self.player prepareToPlay];

   }

-(IBAction)playSong:(id)sender

  {

   if(isPlaying==NO)

    {
      NSLog(@"player should play");
    [player play];
     isPlaying =YES;

     }
       else
        {
         [player pause];
         isPlaying = NO;

        }

 }

I am getting song length "Song :3811456l", so why its not playing it?? please help me find error,Thanks

1)

You don't know what problem your audio player is having because you are not looking at the error returned by this line in your code:

self.player= [[AVAudioPlayer alloc] initWithData:audioData error:nil];

Change it to:

NSError *error;
self.player= [[AVAudioPlayer alloc] initWithData:audioData error:&error];
if(!self.player)
{
    NSLog(@"error opening AVAudioPlayer - %@", [error localizedDescription]);
}

2)

In your "playSong" IBAction, you should be referring to your "self.player" property.

  • and are you still getting a reasonable looking size number for your audio data? what is the URL you are trying to load? is it a URL or is it a string that contains a URL? – Michael Dautermann May 20 '14 at 20:02
