Hi,
This has been bugging me for a while and today, I've managed to grab some time
in order to try and get it working.
I based my class on the Street Scroller Sample App from Apple. The main
methods that are important in Street Scroller are:
- (void)recenterIfNecessary
{
CGPoint
Hi,
Got it working! The problem was partly due to tiredness and partly due to a
misunderstanding about when layoutSubviews gets called.
If you look at the Street Scroller sample, you'll see that it has its content
in-built, in fact it generate new content on the fly. The problem I had was

Thanks Kyle,
That's what I was trying to figure out, whether I needed to re-layout the
views based on the positions or whether I could just do it by keeping an
Array of the image views separately and rotating this as it

I finally managed to get back on this! I've got it working when scrolling from
left to right and can detect when the user scrolls past the last item, however,
I can't seem to find a way to detect when the user scrolls to before the first
item.
I get -0 for offset X

Does (scrollView.contentOffset.x = 0) not work? How are you testing for it now?

Well, it never goes less than -0 whatever that means so the is redundant
and 0 is a valid offset, I need to detect a scroll to *before* 0, which I never
get.
Thanks

Hi,
Spoke too soon!
I just can't seem to get my head around this. I can make it work, but I'm
getting into an infinite loop because updating the scroll view is causing the
delegates to fire again (AFAICT). I'm not sure what to put in layoutSubviews
and what to put in the delegate methods.
Did you check the StreetScroller sample?
https://developer.apple.com/library/ios/samplecode/StreetScroller/Introduction/Intro.html#//apple_ref/doc/uid/DTS40011102
it is the same code that was demonstrated in the WWDC 2011 I told you before.

Hi,
Yes, I took a look, but it's not what I want to do. I have a number of variable
width images, not fixed width and all the examples I've seen use pagingEnabled
and have a fixed width.
Also the Street Scroller sample, just creates a label view on demand, which,
again isn't what I want. I
Hi Dave,
What about if you have some repetition of the images? Say the following is a
container UIView that has all of your UIImageViews stacked horizontally and the
width of the following view is far smaller than that of the UIScrollView it's
contained in. The gray areas are duplicated image
Hi,
I'd like to be able to Scroll Infinitely in a Scroll, e.g. when the scrolling
is past the last item in the Scroll start displaying the first and when
scrolling before the first item, starting displaying the last. The items in
this case are UIImageViews and they have a fixed height and a
There’s a WWDC video from 2011 : “Advanced ScrollView Techniques” which
explains one way to do infinite scrolling. Look at 18:08 if it is what you want.

Have you thought about representing your images as cells in a UITableView? If
so, you could use something like BBTableView
(https://github.com/bharath2020/UITableViewTricks). It's a subclass of
UITableView lays out cells along an arc but it also has support for infinite
scrolling, so you could
Hi,
I don't think that will work for me in this case as I need the images to be
scrolled smoothly without gaps and AFAIK, using a table view cell will cause a
gap - you can add a fragment of an image.
Thanks anyway
All the Best

Does it not work to set the row height to the height of each of the images and
then use a custom UITableViewCell that contains a UIImageView that fills the
cell? The other benefit is that you don't have to have more images in memory
than are visible within the table view's frame. (This may not
