UICollectionView effective drag and drop

Question

I am currently trying to implement the UITableView reordering behavior using UICollectionView.

Let\'s call a UItableView TV and a UICollectionVi

Answer 1

Here is another approach:

Key difference is that this solution does not require a "ghost" or "dummy" cell to provide the drag and drop functionality. It simply uses the cell itself. Animations are in line with UITableView. It works by adjusting the collection view layout's private datasource while moving around. Once you let go, it will tell your controller that you can commit the change to your own datasource.

I believe it's a bit simpler to work with for most use cases. Still a work in progress, but yet another way to accomplish this. Most should find this pretty easy to incorporate into their own custom UICollectionViewLayouts.
