title: Suppressing Class Method Not Found Warnings in Xcode
body: <p>I have a class whose methods are determined at runtime, as indicated in my question <a href="https://stackoverflow.com/questions/7185122/dynamic-method-creation-in-objective-c">here</a>.  This works great, but now I have a bunch of warnings that look like the following littering my code:</p>
  
  <pre><code>Class method '+objectIsNotNil:' not found (return type defaults to 'id')
  </code></pre>
  
  <p>While these warnings don't actually affect the build process, they're very annoying and make it harder to spot relevant warnings.  Is there some way to disable them, but only for the <code>Assert</code> class (maybe some kind of macro)?  If this isn't possible, then is there some way to turn them off for the entire build?</p>
