UICollectionView reloadSections with animation

Question

I'd like to reload UICollectionView with some interesting animation. In UITableView there's a method called reloadSections:withRowAnimation. But in UICollectionView there's just reloadSections.

How can I customize reloadSections animation? I definitely saw this in apps on the App Store.

Answer 1

Just do it like that:

[self.collectionView performBatchUpdates:^{
    [self.collectionView reloadSections:[NSIndexSet indexSetWithIndex:0]];
} completion:nil];
