I have not used a UIScrollView before, and I just wanted to know how I could use paging in a UIScrollView, where there would be a different image on each page, and depending on the page currently selected I would set the image on that page to a separate UIImageView's image.
So if anyone could tell me how to do this that would be great.
The Snipplr reference here gives you a great barebones look into how to set this up.

You need to make use of UIScrollView with paging enabled in order to implement your requirements.
the following link provides example for the same.

In my carousel view after 7 images next image shows the first image , the other one shows the second image although they are different images. I mean after 7 images they start repeat images. I am sure it is coming different images. My images are buttons. When i click them they show detail view. In detail view they show correct images but in carousel not. Do you have any idea what causes that. Thank you.
It sounds like you are using the reusingView feature wrongly.
You can fix it by increasing numberOfVisibleItems, but that's not actually the right way to do it since it uses up more memory and slows down the carousel.
Paste your carousel:viewForItemAtIndex:reusingView: method into the question and I'll check it for you.
I have an app with a few pictures. If the user clicks on one of them, I want him to be able to zoom, pan, scale and so on. I don't need something like Three20. First of all, I'm loading the images from file inside the app, second I don't need the "library" feature (that displays all the images in a grid > like the Photos.app). So I only need the part in the left picture...
How can I do that? Is there any "sample class" or tutorial?
Thanks a lot in advance!
The UIScrollView supports not only scrolling, but also zooming in and out, in fact, it's the super class of things like webViews and tableViews.
It's a matter of fitting an UIImageView inside an UIScrollView and make the contentSize match, and enable zooming (maximum/minimum zooming is 1.0 by default, setting it to something else allows zooming).
check out the Nibmus Project, they have a nice photos controller http://jverkoey.github.com/nimbus/group___nimbus_photos.html, which sounds to be exactly what you're looking for.
i want to display many images and button on each image in a scroll view. and i want the images loaded which are only visible if the user scrolls i want do load the images dynamically. so can i use the Three20 code how to see the actual code for making tiles
in Three20
Yes, Three20 can do that. If I remember correctly, you need to subclass TTPhotoSource and implement code to load the image on-demand from the server.
Interesting classes regarding internet-aware TableViews are TTTableViewDataSource and TTTableViewController Sorry, can't post links for these. New users like me are limited to one link per post.
You find them on Github too. Just look at the "/src/Three20UI/Headers/"-directory
