title: Objective-C: How to call performSelector with a BOOL typed parameter?
body: <p>Is there any way to send a <code>BOOL</code> in selector ?</p>
  <pre><code>[self performSelector:@selector(doSomething:) withObject:YES afterDelay:1.5];
  </code></pre>
  <p>Or I should use <code>NSInvocation</code>? Could somebody write a sample please ?</p>
