HTKDynamicResizingCell

Subclassed UITableView/UICollectionView cells that will auto calculate their size so long as AutoLayout constraints are applied correctly. For iOS 7+. Works similar to how iOS 8's auto sizing of cells work.

HTKDragAndDropCollectionViewLayout

UICollectionViewLayout subclass that works together with a custom UICollectionViewCell to provide drag and drop for a UICollectionView. Works just like UITableView drag and drop. What's unique about this approach is that it does not need to create a "ghost" or "dummy" cell to provide the drag and drop functionality.
