NSDirectoryEnumerator And Subfolders

Question

I have an iPhone app that searches a folder, collates an an array of all the audio files, and lets them be played back. The problem is that if there is a subfolder within the folder I am searching, it will just skip over it/not go into its contents.

My code is as follows:

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
 NSString *documentsDirectory = [paths objectAtIndex:0];
 NSDirectoryEnumerator *direnum = [[NSFileManager defaultManager] enumeratorAtPath:documentsDirectory];

 NSString *pname;

 while (pname = [direnum nextObject])
{
      [musicArray addObject:[pname stringByDeletingPathExtension]];
}

What I want to do is continue to search its subfolders, how would I go about doing that?

Answer 1

It does it automatically. From the documentation:

An enumeration is recursive, including the files of all subdirectories, and crosses device boundaries. An enumeration does not resolve symbolic links, or attempt to traverse symbolic links that point to directories.
