UICollectionReusableView

I have 

UICollectionView
(Multiple selection is allowed) inside 
UICollectionReusableView
. When I select any cell of 
UICollectionView
it changes 
backgroundColor = .blue
and this selection is handled by 
overriding isSelected
property of 
UICollectionCell
. Problem is When I do the scrolling selection is removed and it shows selection in other 
UICollectionReusableView
.

its your duty to tell the cell if its been selecetd when you get it from the resued cell pool、which means you know each cell's selction state and must update each cell when they are reused.
