CAShapeLayer with Path from PointA to PointB
In this method, I used a CAShapeLayer with the correct color and a

For moves, I created another path representing the new position and

CGRectZero is the rectangle at point (0, 0) with zero size. For an
empty rectangle that will work correctly with CGRectUnion you need to
use CGRectNull instead.

Hi,
This sounds like a framework bug. Please file a bug report so we can
make sure it gets fixed (if possible including a test case showing the
issue). thanks,

Hi,
the best way to address this kind of thing is by drawing the shadow
into the layer bitmap. You can do that by subclassing CATextLayer and
adding a drawInContext: method something like:
- (void)drawInContext:(CGContextRef)ctx
{
CGContextSetShadow (ctx, CGSizeMake (0, -4), 2);

Hi,
If you have a fixed set of images you're repeatedly flipping through
you can have CoreAnimation do the animation for you, something like
this:
CAKeyframeAnimation *anim;
NSMutableArray *images;
CGImageRef im;
int i;
images = [NSMutableArray array];

When I implement this, I get the wrong results. It looks like the
pieces do get rotated, but then they're projected flat onto the

flat but with distorted pieces drawn on it.

if you think you've found a memory leak inside of CoreAnimation,
please file a radar (bugreporter.apple.com) with a project showing the

No, there's no way to do that right now, CATiledLayer doesn't even
know when tiles are evicted from the cache. Probably the best thing to
do is to give your cache a maximum size and remove items after they've
been idle for some time…

It means that CA is detecting an OpenGL error while rendering, there's
not much you can do to debug it unfortunately. The best thing would be
