Setting minimum line spacing in collectionView

Question

I'm trying to set the minimum line spacing using swift in my collectionViewController, but i can't seem too find the method i need to use. I need this to be programmatically since i need to change this dynamically depending on the selectedSegmentedIndex. How can i change the minimum line spacing programmatically?

i've tried to add the UICollectionViewFlowLayout, but cant since it's a UICollectionViewController.

i guess i need to use something like.

collectionView:layout:minimumLineSpacingForSectionAtIndex:

Answer 1

Swift 4.2

  func collectionView(_ collectionView: UICollectionView, layout
        collectionViewLayout: UICollectionViewLayout,
                        minimumLineSpacingForSectionAt section: Int) -> CGFloat {

        return 10
    }

Answer 2

Make your UICollectionViewController conform to the protocol UICollectionViewDelegateFlowLayout.

The method you're looking for is:

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumLineSpacingForSectionAtIndex:(NSInteger)section;
