I have a custom view that pretty much shows an ordered list of items
in a grid ( kindof like iPhoto ). This custom view exposes a content
binding. Items in this grid can be reordered by drag n drop. Then this
occurs, i have an NSIndexSet of selected indexes and a drop index
where i need to move all the items to. Whats the best way to do this?
If i just had a normal array, it would be easy just by removing and
adding them back in the right place. But with the array controller, if
i remove then add back in i get two content changes which could
possibly make the view flickr since on content changes, there is some
fade in and moving animations. Am i missing something obvious like a
moveObjectsAtIndexes:toIndex: ?
thx
AC
