No, it's not solved. This works, because it always gives me the same rectangle. As far as I can see this call is broken. As soon as a user drags the scrollbar freely, the numbers go all bunkers as if the visible rectangle had an origin which was a hundred miles down the screen. As a result rowsInRect for tableview doesn't work neither and returns also useless results. Stupid. Is this normal and a known bug, or am I missing something?
