FUIStandardAutoSizingColumnFlowLayout

@MainActor
open class FUIStandardAutoSizingColumnFlowLayout : FUIBaseCollectionViewLayout<FUIStandardAutoSizingColumnSectionLayoutManager>

The FUIStandardAutoSizingColumnFlowLayout resizes collection view cell items, to lay them out according to a specified number of columns. All items per row are top-aligned, though the cell item height may vary, based upon the AutoLayout system’s height calculation for the cell.

Code usage

1. Assign an instance of FUIStandardAutoSizingColumnFlowLayout to your collection view.

   self.collectionView.collectionViewLayout = FUICollectionViewLayout.autosizingColumnFlow
   

2. Implement collectionView(_:cellForItemAt:) dataSource.

   public func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
   let cell = collectionView.dequeueReusableCell(withReuseIdentifier: FUIObjectCollectionViewCell.reuseIdentifier, for: indexPath) as! FUIObjectCollectionViewCell
   //configue cell here
   //...
   return cell
   }
   

3. Implement following methods if you need section header/footer. You can also set headerReferenceHeight/footerReferenceHeight to apply same height for all headers/footers.

   func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -> UICollectionReusableView {
   let view = collectionView.dequeueReusableSupplementaryView(ofKind: UICollectionElementKindSectionHeader, withReuseIdentifier: "Header", for: indexPath) as! FUICollectionSectionHeaderFooterView
   //configue header/footer view here
   //...
   return view
   }
   }
   

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, referenceSizeForHeaderInSection section: Int) -> CGSize { switch section { case 0: return CGSize(width: 40, height: 40) default: return CGSize(width: 60, height: 60) }

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, referenceSizeForFooterInSection section: Int) -> CGSize { switch section { case 0: return CGSize(width: 40, height: 40) default: return CGSize(width: 60, height: 60) }
