how to get last cells and load more data from api

Question

I have a problem with how the last cell appears in the table as well as loading more cells through the API

I would also like to add the Gray Activity Indicator At the bottom of the cells in the queue while loading the cells

Use Alamofire library Swift 5

We can achieve this using the tableview delegate method

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath;

This delegate method is called before tableview uses cell to draw a row which allows us to customise the cell before being displayed. In this override method we get indexPath which can be used to check if the cell is the last one.

For Gray Activity Indicator At the bottom add a custom cell with a Activity indicator along with a label stating "fetching more..........." or else show like below

To Add Activity indicator in tableview

func showIndicator() {
    let spinner = UIActivityIndicatorView(activityIndicatorStyle: .gray)

    spinner.startAnimating()
    tableView.backgroundView = spinner
}

To get last cells and load more data from api

override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
         if yourArr.count-1 == indexPath.row{
            getMoreImages(page)
         }
 }

    func getMoreImages(page:Int){ 
       //hit api
       if api_success == true {
           if self.page == 0 {
              self.yourArr.removeAll()
           }
       self.yourArr.appendContentsOf(api_data)
       self.tableView.reloadData()
       self.page = self.page + 1
       }
    }
