Have you thought about representing your images as cells in a UITableView? If
so, you could use something like BBTableView
(https://github.com/bharath2020/UITableViewTricks). It's a subclass of
UITableView lays out cells along an arc but it also has support for infinite
scrolling, so you could just use the relevant pieces. Plus UITableView will
handle putting the right image in the right vertical location, based on your
data source.
