I propose the follow in replace of 'exchange' and 'append':
- First, the coordinator checks whether we're dropping on a specific index path, and if so, whether the data source implements
[can]dropFrom:(NSIndexPath *)from inCollection:(UIView<I3Collection> *)fromCollection to:(NSIndexPath *)to inCollection(UIView<I3Collection> *)toCollection
- If it does implement these methods and explicitly allows to drop on the given index path, we drop
- If it does implement these methods and explicitly disallows to drop on the given index path, we snap back
- Iff it does not implement these methods, then we check for
[can]dropFrom:(NSIndexPath *)from inCollection:(UIView<I3Collection> *)fromCollection toPoint:(CGPoint)to inCollection(UIView<I3Collection> *)toCollection
(this replaces append)
from between-kit.
To summarise this is the new alg:
- If data source says delete at this drop origin
- Delete
- Else if stop drag on collection && if drag stopped on same collection as origin && valid item at drop origin && data source says rearrangeable
- Rearrange
- Else if drag stopped on different collection
- If data source implements drop on index selectors
- If data source allows drop on index
- Drops on index
- Else
- Reset
- If data source allows drop on index
- Else if data source implements drop on point selectors && can drop on point
- Drops on point
- Else
- Reset
- If data source implements drop on index selectors
- Else
- Reset
