Subclass UICollectionViewFlowLayout to get custom functionality such as animating cells that are added.
After completing part 17, the program seems to work as described, but noticed that the section count does not get updated if we add a new item to a section currently on screen. If I force the section off screen, then bring that section back on, the count is updated. I know we can’t call reloaddata, so what would be fix for this? Should we add a call to update the section count when we add an item?
I’m not understanding. Why do we check for item.representedElementKind == nil before doing the code that follows? Saying it out loud, it’s saying if the represent element kind is nothing, then set it’s frame. Why do we then assume it’s a cell? What else could it be?
Thanks.
@catie Can you please help with this when you get a chance? Thank you - much appreciated! :]
