title: Using NSPredicate to match against a list of integers
body: <p>I have a table with an integer field. I want to select all rows where that field contains any of a few different values.</p>
  
  <p>I'm using this:</p>
  
  <pre><code>[NSPredicate predicateWithFormat:@"myIntValue IN {1,2,3,4}"]
  </code></pre>
  
  <p>but this only returns rows where <code>myIntValue</code> is 1.</p>
  
  <p>What am I doing wrong?</p>
