Duplicated Cell Animation During Batch Update

问题

I have set up a collectionView to have custom reordering behavior via the solution here

However, when a cell is quickly dragged to a new row, the animation shows the dragged cell animate from its original position again (see below):

I am wondering how I could have it just drop the dragged cell at the row it's been dragged to, rather than showing it animate from its original cell again.

回答1:

I have solved this well by increasing the setting the dragged cell's layer.speed property when the interactive movement begins, and then setting it back to 1 when the batchUpdates are completed.
