title: How can you determine if a file exists within the app bundle?
body: <p>Sorry, dumb question number 2 today.  Is it possible to determine if a file is contained within the App Bundle?  I can access files no problem, i.e.,</p>
  
  <pre><code>NSString *pathAndFileName = [[NSBundle mainBundle] pathForResource:fileName ofType:@"plist"];
  </code></pre>
  
  <p>But can't figure out how to check if the file exists there in the first place.</p>
  
  <p>Regards</p>
