A common task when developing iOS apps is to register custom cell subclasses for both UITableView
and UICollectionView
. Well, that is if you don’t use Storyboards, of course.
Both UITableView
and UICollectionView
offer a similar API to register custom cell classes:
public func registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)
