Listing All Files In A Directory

     NSFileManager *fileManager = [NSFileManager defaultManager];
     NSURL *bundleURL = [[NSBundle mainBundle] bundleURL];
     NSArray *contents = [fileManager contentsOfDirectoryAtURL:bundleURL
                           includingPropertiesForKeys:@[]
                                              options:NSDirectoryEnumerationSkipsHiddenFiles
                                                error:nil];

     NSPredicate *predicate = [NSPredicate predicateWithFormat:@"pathExtension ENDSWITH '.png'"];
     for (NSString *path in [contents filteredArrayUsingPredicate:predicate]) {
        // Enumerate each .png file in directory
     }

Recursively Enumerating Files In A Directory

      NSFileManager *fileManager = [NSFileManager defaultManager];
      NSURL *bundleURL = [[NSBundle mainBundle] bundleURL];
      NSDirectoryEnumerator *enumerator = [fileManager enumeratorAtURL:bundleURL
                                   includingPropertiesForKeys:@[NSURLNameKey, NSURLIsDirectoryKey]
                                                     options:NSDirectoryEnumerationSkipsHiddenFiles
                                                errorHandler:^BOOL(NSURL *url, NSError *error)
      {
         NSLog(@"[Error] %@ (%@)", error, url);
      }];

      NSMutableArray *mutableFileURLs = [NSMutableArray array];
      for (NSURL *fileURL in enumerator) {
      NSString *filename;
      [fileURL getResourceValue:&filename forKey:NSURLNameKey error:nil];

      NSNumber *isDirectory;
      [fileURL getResourceValue:&isDirectory forKey:NSURLIsDirectoryKey error:nil];

       // Skip directories with '_' prefix, for example
      if ([filename hasPrefix:@"_"] && [isDirectory boolValue]) {
         [enumerator skipDescendants];
         continue;
       }

      if (![isDirectory boolValue]) {
          [mutableFileURLs addObject:fileURL];
       }
     }
