Hi Cesar,
I had more luck getting rid of the scroll layer and using a 'normal
layer'.

Has a full example of doing the tiled layer stuff with a PDF.
My book has an example on doing the tiled layer stuff with tiled jpg
files;

Good luck!

I have set up a CAScrollLayer with one sublayer, in this case a
CATiledLayer. The documentation say's that CATiledLayer will call
drawLayer:(CALayer*)layer inContext:(CGContextRef) ref as the layer
is needed to be drawn. I cannot see this method being called
currently. My CAScrollLayer, the superlayer has
setNeedsDisplayOnBoundsChange set to YES and a delegate set to draw
the content. The delegate method drawLayer inContext for the scroll
layer is being called. Do i need to do something special to make it
redraw CATiledLayer's layer?
Thanks,
Cesar
