title: Create object from NSString of class name in Objective-C
body: <p>I was wondering if i could create a object of some class if i have the name of the class
  in a NSString.
  I know this is possible in other languages like ActionScript, C# and PHP...</p>
  
  <p>Something like this:</p>
  
  <pre><code>NSString *className = @"AwesomeViewController";
  UIViewController *object = [[className alloc] initWithNibName:className bundle:nil];
  </code></pre>
