I've been trying to figure out a way to do this. The best answer I could find is this one:
UICollectionView horizontal paging with 3 items
However, there are a few issues with it. I am not trying to do exactly what he is doing. Instead I want 3 cells on screen, evenly spaced vertically and horizontally. When I swipe left, I want to see the next 3 cells with the same layout, and so forth. (So, horizontal scrolling only.)
Simply enabling paging leads to the cells not being centered.
I'm aware I can subclass UICollectionViewFlowLayout, but I'm looking for a simpler solution. Enabling paging almost gets what I want, but not quite. Any suggestions?
