You can use NSDirectoryEnumerator via NSFileManager.enumeratorAtPath

From the docs:

NSString *docsDir = [NSHomeDirectory() stringByAppendingPathComponent:  @"Documents"];
NSFileManager *localFileManager=[[NSFileManager alloc] init];
NSDirectoryEnumerator *dirEnum =
    [localFileManager enumeratorAtPath:docsDir];

NSString *file;
while ((file = [dirEnum nextObject])) {
    if ([[file pathExtension] isEqualToString: @"doc"]) {
        // process the document
        [self scanDocument: [docsDir stringByAppendingPathComponent:file]];
    }
}
