To ‘control’ the selection of a TableViewCell when ‘hovering’ over such an item you will have to call this method:

- (NSIndexPath *)indexPathForRowAtPoint:(CGPoint)point 

It’s a method from the UITableView Class and uses the local coordinate system of your tableView. As is mentioned in the Apple Doc: http://developer.apple.com/library/ios/#documentation/uikit/reference/UITableView_Class/Reference/Reference.html

When the method is called you will have a NSIndexPath returned. With it you can select the cell/item at that particular path.
Mind, selecting a path manually doesn’t call the didSelectRowAtIndexPath delegate-method so if you want a certain method called from that delegate you will have to do that manually as well!

This method is prolly called from the touchedDidMove method (where you also do the drag&drop) so getting the point needed for the method shouldn’t be a problem for you.

You will figure it out 🙂
Good luck.
