title: Link to app manage subscriptions in app store
body: <p>Currently with In app purchase the only way to cancel an auto-renewing subscription is to do the following with the device: </p>
  
  <p>Settings > Store > View my account > Manage my subscription</p>
  
  <p>Is it possible programmatically to link directly to the Manage my subscription page in the app store?  I know I can open the app store via something like </p>
  
  <pre><code>NSURL *url = [NSURL URLWithString:@"itms-apps://itunes.apple.com"];
  [[UIApplication sharedApplication] openURL:url];
  </code></pre>
  
  <p>I have seen other apps do this but I can't seem to figure out how.</p>
