-presentationLayer is generated by Core Animation but you can -addAnimation: to it seemingly without ill effect; I was once told that this is an approach akin to using the UIViewAnimationOptionBeginFromCurrentState on iOS, but as I said this is somewhat speculative and from second-hand experience. In any event, it sounds like I misunderstood your problem. I thought the layer was moving because you had added an animation to it, which made me think the problem might be the divergence between the layer and its presentationLayer. This doesn't sound like what you are actually doing, so my idea (valid or not) doesn't really apply here anyway. -- Conrad Shultz Synthetiq Solutions www.synthetiqsolutions.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
