Hi can anyone let me know which control they have used for doing the scrolling.
I like that control very much.

Help me out.
Control is inside: Schedule Tab in the application
Thanks in advance.

Most likely that video is just a UIScrollView. While it shares a lot of the properties of a UITableView
you may notice that a UITableView
is a subclass of a UIScrollView
.
There are a number of ways to create that functionality. I recommend looking at the documentation for UIScrollView
. You may be able to find some glue between a UITableView
and a UIScrollView
. If you decide to write your own UIScrollView
subclass keep in mind memory issues. You will have to unload the "not visible" portions of the view if you are displaying a lot of data.
The UIScrollViewDelegate
protocol has the scrollViewDidScroll:
method that you can use to do custom view layout as the view scrolls.
You can use the contentOffset
property to get the position of what is being displayed in the larger scrollview.
I think you will find its not that hard, once you experiment with UIScrollView. Especially if you aren't planning on do any zooming.
