How to change space between cells in UICollectionView?

I want to reduce the size between cells in row.
Now it looks like:

enter image description here

I'm trying this, for reduce the size between them:

let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 20, left: 2, bottom: 10, right: 2)
layout.minimumInteritemSpacing = 0
layout.minimumLineSpacing = 0


but it doesn't help me. What I do wrong?

Answer
//Objective c
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
        return CGSizeMake((collectionView.frame.size.width/3)-20, 100);
    }


// Swift

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
    return CGSizeMake((collectionView.frame.size.width / 3) - 20, 100)
}
