Ya i also thought that way but the problem is that between two rss
feed there should be a separator image. So if i use scroll layer then
it can be a problem of drawing the image.

Is this the right approach to do it.
In Core Animation if you want to scroll something, then you move its
layer. There is no need to continuously update the content of the
layer, which is what you are proposing with the CAOpenGLLayer
solution. Additionally, your basically just using a GL layer to draw
a bitmap that is continuously updating without any other reason to
use GL, its a waste of resources.
I would highly recommend that you read the Core Animation
Programming Guide before you continue much further, as it may give
you some bigger insights into what is available and how you might
use it. You can find it here: <http://developer.apple.com/documentation/Cocoa/Conceptual/CoreAnimation_guide/Introduction/Introduction.html
