UICollectionView scrolls when a cell is selected

Question

I am having problems when I try to select an element inside a UICollectionView, because when I click on it, it scrolls a bit.

I know that calledSelectItemAtIndexPath is called, but I want to prevent scrolling when selected. I just want the collection view to be viewed when the user scrolls, but if the user just clicks on a cell, he should not move. Only need to choose.

I hope you can help me, since I do not know how to prevent this problem.

Any help would be really appreciated.
