I previously mentioned a UICollectionView extension that allows you to add drag and drop reordering to a UICollectionView grid called LXReorderableCollectionViewFlowLayout.
If youd prefer not to go the UICollectionView route, or dont need reordering heres an open source library that allows you to easily enable drag and drop between any UIViews, even UIPopover views called OBDragDrop from Oblong Industries.
As the readme states:
- Drag and drop between any UIViews
Any view can be draggable, and any view can be a drop target
Visuals exists on a UIWindow that sits on top of the app
Various events for different stages of a drag and drop gesture
Included is an example demonstrating the drag and drop functionality between views including popovers.
You can find OBDragDrop on Github here.
A nice easy way to implement drag and drop functionality between UIViews.
