InfiniteScroller
Microlibrary which simplifies implementation of infinite scroll in UIScrollView.
Motivation
Well in my apps I always deal with the same things again. Every scrolling screen which displays paged data needs to load next page some time. To save some time I created this microlibrary which should deal with everything that is necessary. Every time when user reaches a treshold, the caller is notified and can perform e.g. a network request which fetches new page of data.
Usage
Usage is very simple. Just create an instance of InfiniteScroller with the scrollView you want paged.
let infiniteScroller = InfiniteScroll(scrollView: scrollView)
Add the next page callback.
infiniteScroller.nextPageAction = { [weak self] completion in
loadNextPage { completion() }
}
If you've done all of that then just start the scroller.
infiniteScroller.start()
Then later if your reach last items of your stream, you can stop the scroller by calling stop() method.
Remember to call the completion callback when loading next page finishes
And that's all. Remember that if you loose any reference to the InfiniteScroller instance, it will get deallocated and you will not receive any callbacks so you have to keep strong reference somewhere (e.g. in the view controller).
