Without knowing much about what you're trying to do, two thoughts come
to mind: make your view rectangle smaller than the window frame, or
make the background of your content transparent.
I don't know much of Core Animation, so to the extent that CA is
causing your problem I'm useless to you.

Hi, I have a custom view that takes up the whole frame of my textured
window. Normally, the corners of a textured window are rounded.
However,
since my custom view is rectangular, it draws over the rounded
corners. I am
using Core Animation to draw in the view. I think what I need to do
is clip
my drawing so the corners are transparent, but I haven't been
successful.
What I've tried so far is drawing a rectangle with rounded corners
that
approximates the window's rounded corners using
CGContextAddArcToPoint. Then
I call CGContextClip. But it's not working, all I'm seeing is
garbage at the
window corners, not transparency. Any suggestions?
Thanks,
Dan
