Reordering of NSTableview Rows in View based Table

问题:

As per apple documentation drag and drop NSTableView delegate methods are called only for cell based TableViews not for View based. So there is no way to do reordering of rows using drag & drop for view based NSTableView?

回答1:

I have created a small sample project which has an NSOutlineView where you can add and remove items as well as reorder them. This is not an NSTableView but the implementation of the Drag & Drop protocol is basically identical.

I implemented drag and Drop in one go so it's best to look at this commit.

Drag and drop delegate methods get called fine in a view based NSTableView. There is a great presentation from WWDC '11 on view based table views, and it includes a lengthy discussion about drag and drop. Worth watching.
