There is another option. Using GCD (Grand Central Dispatch).

Example Code :

// Get the filename to load.
    NSString *imageFilename = [imageArray objectAtIndex:[indexPath row]];
    NSString *imagePath = [imageFolder stringByAppendingPathComponent:imageFilename];

    [[cell textLabel] setText:imageFilename];

    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);

    dispatch_async(queue, ^{
        UIImage *image = [UIImage imageWithContentsOfFile:imagePath];

        dispatch_sync(dispatch_get_main_queue(), ^{
            [[cell imageView] setImage:image];
            [cell setNeedsLayout];
        });
    });

Use the same for showing multiple images. Using this will increase the performance of loading tableview definitely.

Refer this to know more about GCD

Try this code. SDWebImage. It downloads image from server and save it to device cache. Also if you don't want save it to cache then you might have a look at AFNetworking.
