title: Using x-apple-reminder:// to launch the Reminders app in iOS
body: <p>Seems simple but I can't make this work.. I want to launch the native Reminders app from my native app.</p>
  
  <p>From what I've read I need to use <code>x-apple-reminder://</code> URL scheme but it does not launch the Reminders app.</p>
  
  <p>Here's my code:</p>
  
  <pre><code>NSString* reminderUrl = @"x-apple-reminder://";
  NSURL *url = [NSURL URLWithString:reminderUrl];
  BOOL ok = [[UIApplication sharedApplication] openURL:url];
  </code></pre>
  
  <p><code>ok</code> is always <code>NO</code> and nothing happens. </p>
  
  <p>I also tried passing in the Reminder's id (my app created it), but that didn't work. (as in <code>x-apple-reminder://REMINDER_GUID</code>)</p>
  
  <p>I suspect that my problem is with the <code>openURL</code> call.. is there some other option?</p>
