FlexibleCollectionViewController

Swift library of generic collection view controller with external data processing of functionality, like determine cell's reuseIdentifier related to indexPath, configuration of requested cell for display and cell selection handler etc

Example

Initialisation with configuration

_flexibleCollectionVC =FlexibleCollectionViewController(collectionViewLayout:CustomFlowLayout(), configuration:CollectionConfiguration(userInteractionEnabled:true, showsHorizontalScrollIndicator:false, isScrollEnabled:true, multipleTouchEnabled:false, backgroundColor:.clear))

Cell and supplementary view registering

_flexibleCollectionVC.register(UICollectionViewCell.self, forCellWithReuseIdentifier:"UICollectionViewCell")
_flexibleCollectionVC.registerSupplementaryView(UIHeaderImageCollectionView.self, kind:.header, reuseIdentifier:UIHeaderImageCollectionView.reuseIdentifier)

Requesting indentifier of cell for specific indexPath

_flexibleCollectionVC.requestCellIdentifier ={ value inreturn"UICollectionViewCell"}

Requesting indentifier of supplementary view for specific indexPath

_flexibleCollectionVC.requestSupplementaryIdentifier ={ value inreturnUIHeaderImageCollectionView.reuseIdentifier
}

Configuration of input cell with related data to indexPath

_flexibleCollectionVC.configureCell ={(cell:UICollectionViewCell, data:CollectionImageCellData?, indexPath:IndexPath)inguardlet data = data else{returnfalse}
cell.backgroundColor = data.color
returntrue}

Configuration of supplementary view with related kind and data to indexPath

_flexibleCollectionVC.configureSupplementary ={(view:UICollectionReusableView, kind:SupplementaryKind, data:CollectionImageCellData?, indexPath:IndexPath)iniflet view = view as?UIHeaderImageCollectionView,let data = data {
view.text = data.category
returntrue}returnfalse}

Process cell selection to related indexPath

_flexibleCollectionVC.cellDidSelect ={ value inreturn(deselect:true, animate:true)}

Estimate cell size

_flexibleCollectionVC.estimateCellSize ={ value inguardlet layout = value.1as?UICollectionViewFlowLayoutelse{returnnil}letcol:CGFloat=3letwidth= value.0.bounds.width-(layout.sectionInset.left+layout.sectionInset.right)letside=round(width/col)-layout.minimumInteritemSpacing
returnCGSize(width: side, height: side)}

Put predefined cells in generated order related to ListGenerator

_flexibleCollectionVC.setData(getData())
