Swift tableView Pagination

Question

I have success working tableview with json parsing codes.But may have 1000 more item so need pagination when scrolling bottom side. I dont know how can i do this my codes un

Answer 1

I've tried an approach with willDisplayCell. But it produces unwanted stops during scrolling which makes the user experience not good. I think a better way is to do it in scrollViewDidEndDecelerating delegate method. It calls when the scroll finishes and only then new data comes. User sees that there is new content and scroll again if he wants. I've taken the answer here but instead of scrollViewDidEndDragging I use scrollViewDidEndDecelerating. It looks just better in my case. Here is some code from my project.

func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
    guard scrollView == tableView,
        (scrollView.contentOffset.y + scrollView.frame.size.height) >= scrollView.contentSize.height,
        !viewModel.isLastPeriodicsPage else { return }

    viewModel.paginatePeriodics(tableView.getLastIndexPath())
}
