How to center a UICollectionView when it is tapped?

Question

I have a UICollectionView and it has quite a lot of UICollectionViewCells on it. I want to scroll the cell to the centre of the UICollectionView<

Answer 1

It seems that this bug is caused by a bad interaction between the scroll view's contentInset and UICollectionViewFlowLayout. In my testing, setting layout.sectionInset rather than collectionView.contentInset eliminated the problem.

Based on the accepted answer above, I would eliminate the workaround, and change:

[collectionView setContentInset:UIEdgeInsetsMake(collectionViewHeight / 2, 0, collectionViewHeight / 2, 0)];

to

[layout setSectionInset:UIEdgeInsetsMake(collectionViewHeight / 2, 0, collectionViewHeight / 2, 0)];
