Answer 1

Try this:

- (ViewController *) init {
    if (self = [super init]) self.title = @"Text Files";

    // get the list of all files and directories
    NSFileManager *fM = [NSFileManager defaultManager];
    fileList = [[fM directoryContentsAtPath:DOCUMENTS_FOLDER] retain];
    NSMutableArray *directoryList = [[NSMutableArray alloc] init];
    for(NSString *file in fileList) {
        NSString *path = [DOCUMENTS_FOLDER stringByAppendingPathComponent:file];
        BOOL isDir = NO;
        [fM fileExistsAtPath:path isDirectory:(&isDir)];
        if(isDir) {
            [directoryList addObject:file];
        }
    }

    NSLog(@"%@", directoryList);

    return self;
}

Mrueg wrote it all but one thing that

fileList = [[fM directoryContentsAtPath:DOCUMENTS_FOLDER];

Replace by

fileList = [fileManager contentsOfDirectoryAtPath:filePath error:nil];
