I know that you can have some degree of control over the insert and delete animations of UICollectionViews by overriding the UICollectionViewLayoutmethods
initialLayoutAttributesForAppearingItemAtIndexPath: for insertions
finalLayoutAttributesForDisappearingItemAtIndexPath: for deletions
... but is there a way to change the animation's duration (e.g. to something much slower — 2 seconds or so?) or its animation curve?
