Is anyone aware of a way with JS to detect interaction with the native UI in mobile Safari. An example event would be a click on the URL bar or the bookmarks icon. I'd like to be able to trigger a change on the page with JS on these events.

Any ideas?

No, JavaScript does not have access to these events. You would need to use a plug-in.

Your best hope is to detect the mouse leaving the browser pane.
