UICollectionView leaves blank cells while scrolling

Question

I have built a uicollectionview that shows the thumbnails of images. Every thing works fine until.

I delete a photo from the end of the collection view and scroll to top.

So the problem is when i scroll from bottom back to top it leaves these blank cells. But if i delete from top of collection view and scroll to bottom then it doesnt leave these blank cells.

I dont know what is causing it. I am very sure that the UICollectionViewDataSource are updated properly.

Please help me with this.

Answer 1

To answer my own question. Its a bug. Reducing the cell size fixed the problem. I just reduced the cell width and the problem is fixed.
