Bug: Disappearing and flashing TableViewCells

[FramusRock]

Hey,

First of all thanks for this neat drag-to-reorder addition!
But I've got some issues with it: Sometimes when I start dragging my TableViewCell will simply disappear (so the overlay that you use to still show it is not visible). When the user drags around, he will see an invisible spot moving.

Another thing that happens often is that when releasing the reordering, the cell released flashes for a split second between two different contents. So it shows the content of another cell, then switching back to its actual (and right) content.

I was having a similar issue. I managed to fix it by implementing - (UITableViewCell*) cellIdenticalToCellAtIndexPath:(NSIndexPath *)indexPath forDragTableViewController:(ATSDragToReorderTableViewController *)dragTableViewController on my subclass. I think the problem was due to the fact that originally it would have just used a dequeued cell for the dragged cell under my setup, breaking the assumption that the view representing the dragged cell was separate from the cell supposedly under it at that index path (memory address comparison revealed them to be the same until I implemented that method).
