I see that you have already answered this question, but still want to share my experience.

I had the same problem.

In my case, the reason of this problem was the following function: collectionView.dequeueReusableCell(...).

The type of cells was the same in every case, but data was different:

• In some cases data for a specific cell contained an image.
• In some cases data for a specific cell did not contain an image, it was nil.

When image was nil I was not setting an image to the imageView. In such case collection view reuses an image of of other cell (Wrong image for a current cell).

Solution is very simple: Just set nil, if imageView does not contain an image.

Hope this will help you.
