Here's the slowest(?) approach:

NSFileManager * fileManager = [NSFileManager new];
NSArray * subpaths = [fileManager subpathsAtPath:path];

but that should at least point you to a more specialized implementation for your needs.

Slightly lower level abstractions which allow you to enumerate on demand include NSDirectoryEnumerator and CFURLEnumerator. Depending on the depth of the directory, these have the potential to save much unnecessary interactions with the filesystem, compared to -[NSFileManager subpathsAtPath:].
