title: How to play audio file on websites on iPhone?
body: <p>I want to play an audio file which is posted on a website. I'm trying to use AVAudioPlayer and set the url to its website link. But the bgPlayer turns out to be nil. I think I can download this audio file and play it afterwards, but is there any way to play it while I'm downloading it?</p>
  
  <pre><code>NSURL *bgURL = [NSURL URLWithString:@"http://www.radioslots.com/iphone/test/tmp/1.mp3"];
  bgPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:bgURL error:nil];
  bgPlayer.numberOfLoops = -1;
  if (bgPlayer) {
      [bgPlayer play];
  }
  </code></pre>
