title: How to use iPhone Custom URL schemes
body: <p>I've got an app that I want to be able to use Custom URL schemes for. I want users to be able to open Tweetie using the Custom URL protocol however I need to populate the tweet with dynamic website link which I get using currentItem.link.</p>
  
  <p>I found this code which launches Tweetie and populates a message with static information:</p>
  
  <pre><code>NSString *shortened_url = @"http://your.url.com";
  NSString *stringURL = [NSString stringWithFormat:@"tweetie://%@", shortened_url];
  NSURL *url = [NSURL URLWithString:stringURL];
  [[UIApplication sharedApplication] openURL:url];
  </code></pre>
  
  <p>So using the above code how would I populate the message with currentItem.link information?</p>
  
  <p>Thanks.</p>
