UICollectionView: Get indexPath of Cell that is not visible

I have a UICollectionView with several cells – there are always some of them outside the viewport, so there are cells being reused.

When an event occurs I want to take a specific cell and move it to the front of the UICollectionView. In order to make moveItemAtIndexPath() work I need to know the current indexPath of the Cell that I want to move.

When I initialize the Cells in the CollectionViewDelegate with the cellForItemAtIndexPath method I save its indexPath into a variable of the Object that is the model of the Cell (not it’s actual Object, just the model). Then I look at this variable when I want to move the cell.

This is working fine as long as the cell was visible once – it seems like it only initiated then, even though it is part of the CollectionViewData all the time.

How can I make sure my CollectionViewCell has an indexPath, even when it is not visible or has not been visible yet?

If you know what data (cell) you want to present at the front (I assume top) of your UICollectionView, why don't you just update your dataSource and reload your UICollectionView?
