Horizontal UIScrollView and hundreds of thumbnail images in iOS?

You can add all the thumbnails programatically to your scrollview and use the setContentSize method of UIScrollView. you have to pass 2 values in contentOffset. 1 for width and 1 for height. Please follow link to explore more on this. If you need further help please leave a comment.

Hope it helps.

Please consider Following example.

- (void)setupHorizontalScrollView{scrollView.delegate = self;[self.scrollView setBackgroundColor:[UIColor blackColor]];[scrollView setCanCancelContentTouches:NO];scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;scrollView.clipsToBounds = NO;scrollView.scrollEnabled = YES;scrollView.pagingEnabled = YES;NSUInteger nimages = 0;NSInteger tot=0;CGFloat cx = 0;for (; ; nimages++) {    NSString *imageName = [NSString stringWithFormat:@"image%d.jpg", (nimages + 1)];    UIImage *image = [UIImage imageNamed:imageName];    if (tot==15) {        break;    }    if (4==nimages) {        nimages=0;    }    UIImageView *imageView = [[UIImageView alloc] initWithImage:image];    CGRect rect = imageView.frame;    rect.size.height = 40;    rect.size.width = 40;    rect.origin.x = cx;    rect.origin.y = 0;    imageView.frame = rect;    [scrollView addSubview:imageView];    [imageView release];    cx += imageView.frame.size.width+5;    tot++;}self.pageControl.numberOfPages = nimages;[scrollView setContentSize:CGSizeMake(cx, [scrollView bounds].size.height)];}

I suggest you to look at nimbus

Check out bjhomer's HSImageSidebarView project. It lets you load a scrollview horizontally or vertically and load in the images. Super easy to implement.
