body: <p>I am creating an iPhone app where the user browse and download iTunes podcasts. </p>
  
  <p>I am trying to find out how to play an audio podcast. This is what I have tried:</p>
  
  <pre><code>-(IBAction)play
  {
      NSURL *urli=[NSURL URLWithString:@"https://itunes.apple.com/sa/podcast/mwq-alqary-bdalrhmn-bn-jmal/id539157991?mt=2#"];
      p = [[MPMoviePlayerController alloc] initWithContentURL:urli];
  
      [p play];
  }
  </code></pre>
  
  <p>but I don't hear any sound.</p>
