title: Objective C Boolean Array
body: <p>I need to utilize an array of booleans in objective-c. I've got it mostly set up, but the compiler throws a warning at the following statement:</p>
  
  <pre><code>[updated_users replaceObjectAtIndex:index withObject:YES];
  </code></pre>
  
  <p>This is, I'm sure, because YES is simply not an object; it's a primitive. Regardless, I need to do this, and would greatly appreciate advice on how to accomplish it.</p>
  
  <p>Thanks.</p>
