Get directory contents in date modified order

Question

Is there an method to get the contents of a folder in a particular order? I\'d like an array of file attribute dictionaries (or just file names) ordered by date modified.

How about this:

// Application documents directory
NSURL *documentsURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];

NSArray *directoryContent = [[NSFileManager defaultManager] contentsOfDirectoryAtURL:documentsURL
                                                          includingPropertiesForKeys:@[NSURLContentModificationDateKey]
                                                                             options:NSDirectoryEnumerationSkipsHiddenFiles
                                                                               error:nil];

NSArray *sortedContent = [directoryContent sortedArrayUsingComparator:
                        ^(NSURL *file1, NSURL *file2)
                        {
                            // compare
                            NSDate *file1Date;
                            [file1 getResourceValue:&file1Date forKey:NSURLContentModificationDateKey error:nil];

                            NSDate *file2Date;
                            [file2 getResourceValue:&file2Date forKey:NSURLContentModificationDateKey error:nil];

                            // Ascending:
                            return [file1Date compare: file2Date];
                            // Descending:
                            //return [file2Date compare: file1Date];
                        }];
