Hello, I have a 10.11+ NSCollectionView. I have two representations (subclasses of NSCollectionViewItem) of the data - one large and one small. When the view is resized to be narrower than the large representation, I’d like to swap the views to the smaller versions. Similarly, when the window is widened enough to accommodate at least a single of the larger views, I’d like the views to change again. I’ve not been able to make this work.
I have set up an NSViewBoundsDidChangeNotification so I know when the width of the view crosses the threshold. I’ve tried: - [collectionView reloadData] - [collectionView.collectionViewLayout invalidateLayout] (on the NSCollectionViewFlowLayout) I think I just want to invalidate all of the already created views and get the collection view to call makeItemWithIdentifier:forIndexPath: again. One option I haven’t explored is to handle the change within a single NSCollectionViewItem subclass (two views in the one .xib), but since the representations are sufficiently different (e.g different number of subviews) I’m worried about running into auto layout issues during the transition. Also it feels messier. Bonus points for how to accomplish this with animation!
