title: How do I use C++ STL containers in My iPhone App?
body: <p>I'd like to use an STL set in my iPhone app (which is written in Objective-C in XCode).  How do I include set and/or use the standard namespace?</p>
  
  <p>In C++ I'd do this:</p>
  
  <pre><code>#include&lt;set&gt;
  using namespace std;
  
  // use the set&lt;T&gt; somewhere down here...
  </code></pre>
  
  <p>How can I do this in Objective-C?</p>
