UICollectionView animate items after reloadItemsAtIndexPaths is called (fade animation).

Is there a way to avoid this animation?

iOS 6

It's worth noting that if you're targeting iOS 7 and above, you can use the new UIView method performWithoutAnimation:. I suspect that under the hood this is doing much the same as the other answers here (temporarily disabling UIView animations / Core Animation actions), but the syntax is nice and clean.

So for this question in particular...

Objective-C:

[UIView performWithoutAnimation:^{
    [self.collectionView reloadItemsAtIndexPaths:indexPaths];
}];


Swift:

UIView.performWithoutAnimation {
    self.collectionView.reloadItemsAtIndexPaths(indexPaths)
}


Of course this principle can be applied for any situation that you want to ensure a change is not animated.
