dropOperation()
Returns the current drop operation.
Declaration
func dropOperation() -> IKImageBrowserDropOperationReturn Value
IKImageBrowserDropOn if the drop occurs on an item, otherwise IKImageBrowserDropBefore.
Discussion
The returned value is valid when a drop occurred and until next drop.
For example, given a browser with N cells , a cell of N-1 and operation of IKImageBrowserDropOn would specify a drop on the last cell. To specify a drop after the last cell, one would use an index of N and IKImageBrowserDropBefore for the operation.
