title: How can I stop a stream when using STTWitter
body: <p>On iOS (but I think this would be just the same on OSX) I'm using <a href="https://github.com/nst/STTwitter" rel="nofollow">STTWitter</a>.</p>
  
  <p>Among other things, I want to use it to stream the main public timeline.</p>
  
  <p>I've successfully used <code>getStatusesSampleDelimited:stallWarnings:progressBlock:stallWarningBlock:errorBlock:</code> to start streaming tweets.</p>
  
  <p>How can I stop the stream once I've got enough, or want to switch to a different stream (e.g. streaming a search)?</p>
  
  <p>I've tried destroying the <code>STTWitterAPI</code> object - with no effect. I can't see a method on the object to stop streaming, and I've traced the source code through and don't see any way I can stop a stream once it's started.</p>
  
  <p>What have I missed?</p>
