Cell spacing in UICollectionView

Question

How do I set cell spacing in a section of UICollectionView? I know there is a property minimumInteritemSpacing I have set it to 5.0 still the spaci

Answer 1

Remember, it is minimum line space, not minimum inter item spacing or cell space. Because your collectionView's scroll direction is HORIZONTAL.

If it is vertical then you need to set cell space or inter item space for horizontal space between cells and line spacing for vertical space between cells.

Objective-C version

- (CGFloat)collectionView:(UICollectionView *)collectionView
                       layout:(UICollectionViewLayout*)collectionViewLayout
    minimumLineSpacingForSectionAtIndex:(NSInteger)section
    {
        return 20;
    }

Swift version:

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
    return 20
}
