title: How to remove a directory and its contents using NSFileManager
body: <p>New to Objective C. I have created a few directories which contain pdf files for an iPhone app. How can I delete a directory and its contents using NSFileManager?</p>
  
  <p>Do I need to loop through and remove the contents first? Any code samples would be much appreciated.</p>
  
  <p>Thanks in advance.</p>
