UICollectionView doesn't update all cells properly via cellForItemAt

QUESTION

UICollectionView doesn't update all cells properly via cellForItemAt

Asked 2020-Mar-02 at 20:40

I have the following setup: a UICollectionView with a custom cell, where the user can select multiple cells and then perform some heavy image operation. Now I try to update the selected cells which the user selected with the result of that operation, which will be produced by a function of the subclassed custom cell. For all visible cells, the function is called on button press by the user and for all other cells, this happens via cellForItemAt in order to be most efficient.

However, I face the problem now, that the visible cells are all updated but then after scrolling the cells right behind or before the visible cells do not get updated via cellForItemAt but only when scrolling forth and back. Please see the attached video.

For demonstration purposes I just show a green UIView for the image operation. Because that operation is resource heavy, I cannot use any of the UICollectionView reloadData or similar, as they would deselect the selected cells, and manual re-selection will cause flickering.

UICollectionView defaults to prefetchingEnabled == YES, which means that the collection view will request cells before it needs to display them. If the app's state changes such that the cells that have already been fetched need to be displayed differently, you can implement the collectionView:willDisplayCell:forItemAtIndexPath: method to update the cell.

It looks like this is exactly your problem... you turn on a feature that should change the way the cells look, but the cells that have been fetched but which aren't visible don't get updated. Implementing collectionView:willDisplayCell:forItemAtIndexPath: should solve the problem.
