I am using a spinner in bottom of tableView to show the spinner when data is reloading.

var sneakers: [sneakerModel] = 

I stored all my data in sneakers and returning the count on numberOfRowsInSection method.

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return self.sneakers.count

}

And now I am using willDisplay method to show the spinner in bottom.

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {



let lastSectionIndex = tableView.numberOfSections - 1

let lastRowIndex = tableView.numberOfRows(inSection: lastSectionIndex) - 1



if indexPath.row == self.sneakers.count - 1 && !didPageEnd {

    pageNo += 1

    getSneakerSearch()

 }



    if (indexPath.row == self.sneakers.count) {

       self.tableView.tableFooterView?.isHidden = true

    } else {



    if indexPath.section ==  lastSectionIndex && indexPath.row == lastRowIndex {

     let spinner = UIActivityIndicatorView(activityIndicatorStyle: .gray)

     spinner.activityIndicatorViewStyle = .whiteLarge

     spinner.color = .red

     spinner.startAnimating()

     spinner.frame = CGRect(x: CGFloat(0), y: CGFloat(5), width: tableView.bounds.width, height: CGFloat(44))



     self.tableView.tableFooterView = spinner

     self.tableView.tableFooterView?.isHidden = false

        }



    }



}

But it is not working. How can I stop spinner when no more data is loading. Please help?

Getting the data from api.

func getSneakerSearch() {



   let param: [String:Any] = [ "search_term" :  searchText ?? "","page": pageNo, "token": commonClass.sharedInstance.userToken ?? ""]



    if self.pageNo == 0{

        commonClass.sharedInstance.startLoading()

    }

    Alamofire.request(Constants.API.url("search"), method: .post, parameters: param, encoding: URLEncoding.httpBody, headers: nil).responseJSON {

        (response:DataResponse<Any>) in



        commonClass.sharedInstance.stopLoading()



        guard let json = response.result.value as? [String:Any] else {return}

        printD(json)



        guard let status = json["status"] as? Int else {return}

        printD(status)





        if status == 1 {



            guard let data = json["data"] as? [[String:Any]] else { return}

            printD(data)

            if self.pageNo == 0 {

                self.sneakers.removeAll()

            }

            for item in data {

                guard let description =  item["description"] as? String else { return}

                printD(description)

                self.sneakers.append(sneakerModel(response: item))

            }

            self.didPageEnd = data.count < limitPerPage



        }

        DispatchQueue.main.async {

            self.reloadData()

        }

    }

}

Create loadingview in viewdidload

override func viewDidLoad() {

    super.viewDidLoad()

    let spinner = UIActivityIndicatorView(activityIndicatorStyle: .gray)

    spinner.activityIndicatorViewStyle = .whiteLarge

    spinner.color = .red

    spinner.startAnimating()

    spinner.frame = CGRect(x: CGFloat(0), y: CGFloat(5), width: tableView.bounds.width, height: CGFloat(44))



    self.tableView.tableFooterView = spinner

    self.tableView.tableFooterView?.isHidden = true

}

and update willDisplay cell

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {



    let lastSectionIndex = tableView.numberOfSections - 1

    let lastRowIndex = tableView.numberOfRows(inSection: lastSectionIndex) - 1



    if indexPath.row == self.sneakers.count - 1 && !didPageEnd {

        pageNo += 1

        getSneakerSearch()

    }

}

Update getSnackerSearch func:

...

    if self.pageNo == 0{

        commonClass.sharedInstance.startLoading()

    }else{

        self.tableView.tableFooterView?.isHidden = false

    }

    Alamofire.request(Constants.API.url("search"), method: .post, parameters: param, encoding: URLEncoding.httpBody, headers: nil).responseJSON {

        (response:DataResponse<Any>) in



        if self.pageNo == 0{

            commonClass.sharedInstance.stopLoading()

        }else{

            self.tableView.tableFooterView?.isHidden = true

        }



    }

   ...

For center of you spinner to tableview you can follow these steps to do it. You don't need to provide height and width for spinner.

    let spinner = UIActivityIndicatorView(activityIndicatorStyle: .gray)

    spinner.activityIndicatorViewStyle = .whiteLarge

    spinner.color = .red

    spinner.startAnimating()



    let topBarHeight = UIApplication.shared.statusBarFrame.size.height +

        (self.navigationController?.navigationBar.frame.height ?? 0.0)



    spinner.center=CGPointMake(self.tableView.center.x, self.tableView.center.y- topBarHeight);
