title: Cast a BOOL to id in Objective-C
body: <p>This is my code:</p>
  
  <pre><code>[delegate performSelectorOnMainThread:@selector(setVariablePremierAffichage:) withObject:TRUE waitUntilDone:NO];
  </code></pre>
  
  <p>The problem is that the argument "withObject" only takes an "id" type, so, how can I cast my value "TRUE" to an id type? I also use ARC memory management in Xcode for iOS 5.</p>
