hello everyone.
i'm totally new to the mac platform but already feel comfortable with the
cocoa frameworks.
i am developing an ipad app which offers a full screen UIScrollView which
itself has several subviews, representing the pages the user can flip
through.
problem is: every subview renders a pdf page and does so on-demand, lazy,
when it slides into view.
i would like the subview right and left from the currently visible view
being pre-rendered (like facebook's app does in galleries) so that the user
doesn't see all the CATiledLayers be fading in.
i experimented with -setNeedsDisplay and -setNeedsLayout but have had no
success.
is there something someone can point me to?
been crawling through the docs and google for over a week now...
thanks in advance,
martin
