UICollectionView Flow layout no fixed row height

问题

How to modify the flow layout, so that there is the same vertical spacing between the smaller and larger cells (eg. there is no fixed row height / the row height is not fixed to the maximal size)?

I want to look it like this

The solution was using UICollectionViewWaterfallLayout

Follow the setup from the website, and you can setup it like this

- (void)viewDidLoad
{
    [super viewDidLoad];

    UICollectionViewWaterfallLayout * layout = (UICollectionViewWaterfallLayout *)self.collectionView.collectionViewLayout;
    layout.delegate = self;
    layout.columnCount = 2;
    layout.itemWidth = 150.f;
    layout.sectionInset = UIEdgeInsetsZero;

    ...
}
