I am using a UIDynamicAnimator's UISnapBehavior to animate these circles between two states: http://cl.ly/image/1G3p1B2x2v14/Image%202013.09.24%2011%3A35%3A43%20AM.png
That works great. However, I then put this inside a UIScrollView. When I scroll before the UISnapBehavior animation has "settled" (there seems to be a delay after it looks like it finishes and when it actually finishes), the circles lose their relative positioning to the scroll container: http://cl.ly/image/1E0I3l460J1V/Image%202013.09.24%2011%3A32%3A10%20AM.png
When I scroll after waiting a few seconds after the animation has "settled", the circles do not lose their relative positioning
I'm assuming this is because UISnapBehavior animates things with fixed positions, and then reverts back to relative positioning after it finishes, but I'm not sure if that's true.
