I've got a blog post in the editing phase describing all the things we
do to get NSScrollViews working, but the only other thing we do that I
can think of is to swizzle -[NSClipView scrollToPoint:] to look like
the following:
- (void)scrollToPoint:(NSPoint)newOrigin {
originalScrollToPoint(self, _cmd, newOrigin);
[self fixLayerGeometry];
[[self subviews] makeObjectsPerformSelector:@selector(fixLayerGeometry)];
}
-[NSView(LayerBackedFix) fixLayerGeometry] is defined like this:
- (void)fixLayerGeometry {
if (![self layer])
return;
[CATransaction begin];
[CATransaction setDisableActions:YES];
for (NSView *subview in [self subviews]) {
CALayer *layer = [subview layer];
CGPoint layerPosition = NSPointToCGPoint([self
convertPointToBase:[subview frame].origin]); // note: on Lion, we want
to use -convertPointToBacking: instead.
layer.position = layerPosition;
}
[CATransaction commit];
}
Pay attention to that note, since on Lion base coordinate systems
don't mean the same thing as backing coordinate systems.
I'm going to CC this to the list, since it's helpful information.
Hope that helps!
