cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
//I dont know what put here for display from sqlite
NSUInteger row = [indexPath row];
cell.textLabel.text = [array1 objectAtIndex:row];
//cell.detailTextLabel.text = [array2 objectAtIndex:row];
NSString *b = [array2 objectAtIndex:row];
NSLog(#"b=%#",b);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(#"%#",paths);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSError *error = nil;
NSArray *imageFileNames = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:[documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#",b]] error:&error];
NSLog(#"file=%#",imageFileNames);
NSMutableArray *images = [[NSMutableArray alloc ] init];
for (int i = 0; i < [imageFileNames count]; i++)
{
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#/%d.png",b, i]];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
[images addObject:img];
NSLog(#"%#",getImagePath);
}
NSLog(#"images=%#",images);
cell.imageView.image=[imageFileNames objectAtIndex:0];
//NSLog(#"row=%u",row);
return cell;
}

I think what you are looking at is something like this (please modify to your liking):
NSString *documents = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
self.contents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documents error:NULL];
...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.fileLabel.text = [self.contents objectAtIndex:indexPath.row];
// Build Documents Path with Folder Name
NSString *documents = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *directory = [documents stringByAppendingPathComponent:[self.contents objectAtIndex:indexPath.row]];
NSFileManager *fM = [NSFileManager defaultManager];
// Get Attributes
NSDictionary *fileAttributes = [fM attributesOfItemAtPath:directory error:NULL];
// Check if it's a directory
if ([fileAttributes objectForKey:NSFileType] == NSFileTypeDirectory) {
// Get contents of directory
NSArray *insideDirectory = [fM contentsOfDirectoryAtPath:directory error:NULL];
cell.folderImageView.image = nil;
// Loop through folder contents
for (NSString *file in insideDirectory) {
if ([[[file pathExtension] uppercaseString] isEqualToString:#"PNG"]) {
NSString *imagePath = [directory stringByAppendingPathComponent:file];
UIImage *image = [UIImage imageWithContentsOfFile:imagePath];
cell.imageView.image = image;
break;
}
}
}
return cell;
}

You can directly use [UIImage imageNamed:#""] for images rather than imageWithContentsOfFile
