I was wondering if anyone had made any progress on this? I've tried subclassing Ext.Container and modifying the CSS to enable native scrolling for the container's content. I can get it to work on Chrome and Safari but not on iOS.
I've tested the native scrolling (in a simple static HTML file) with a huge grid of images (over 200 images ~15kb each) and the performance is perfect on my iPhone 4. The same layout with only 25 images using Sencha's scrolling is extremely choppy.
I've tried the following CSS on the container's "x-inner" element, but to no avail:
Any tips would be greatly appreciated.
