pinch again during animation

[adriantofan]

Hello guys,

First of all thank you for this awesome library !

I have a crash in my app made after your pinch example. Basically if I pinch and let, there is a animation that continues until it stabilizes. If I pinch again during this animation I get an exception

2015-05-07 17:46:49.804 Tradee[4684:1227320] *** Assertion failure in -[UICollectionView _finishInteractiveTransitionShouldFinish:finalAnimation:], /SourceCache/UIKit/UIKit-3347.44/UICollectionView.m:2897
2015-05-07 17:47:03.124 Tradee[4684:1227320] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'the collection was not prepared for an interactive transition. see startInteractiveTransitionToCollectionViewLayout:completion:'

Any ideas on how to fix this ? Or maybe point me in the right direction ?

Thank you,
Adrian

Hello ,

I've disabled the pinch during the animation and reenalbled-it inside the competition block. Seems to fix the issue. Please let me know if you wish me to fix the demo.
