against a public API point for that?
Probably because there’s no way to accurately know the physical screen size of
a device attached via AirPlay or HDMI cable. The API would break in such cases.

Dynamically at runtime, I'd like to put a fixed banner across the top of a

There’s a WWDC video from 2011 : “Advanced ScrollView Techniques” which
explains one way to do infinite scrolling. Look at 18:08 if it is what you want.

on opaque images, you won’t have the best rendering method possible if your

Hi,
I have to code a table visually like the UITableView on iOS, but with one
caveat : it should support some kind of animation in each cell, like the swipe
