(Tutorial Ios) Pull To Refresh With Uirefreshcontrol

Hello guys, pada kesempatan sebelumnya aku sudah menjelaskan wacana bagaimana menciptakan custom tableview di ios. Bisa dilihat di sini https://andronut.blogspot.com//search?q=tutorial-ios-custom-uitableviewcell-in.

Tutorial kali ini intinya meneruskan tutorial yang sebelumnya yakni dengan menambahkan Pull to Refresh. Untuk menciptakan pull to refresh di iOS sanggup memakai widget yang dinamakan UIRefreshControl. Implementasinya cukup sederhana yakni dengan menempakannya ke dalam table view yang kita buat.

Oke, eksklusif aja ke TKP.

Pertama, deklarasikan variabel UIRefreshControl berikut.

let pullRefresh = UIRefreshControl() 

Buat function untuk menghandle refresh control. Di sini lah kawasan menghandle network request. Untuk sementara aku memakai thread biasa.

func pullRefresh(_ refreshControl: UIRefreshControl) {     // do network request here              DispatchQueue.main.asyncAfter(deadline: .now() + 3) {         self.tableView.reloadData()         refreshControl.endRefreshing()     } } 

Lalu atur properties-nya (warna, text, dll) sesuai keinginan.

// Refresh Control Properties pullRefresh.addTarget(self, action: #selector(ViewController.pullRefresh(_:)), for: UIControlEvents.valueChanged)          pullRefresh.tintColor = UIColor.red pullRefresh.attributedTitle = NSAttributedString(string: "Please wait ...") 

Kemudian tambakan ke dalam tableview sebagai subview.

// Add to Table View if #available(iOS 10.0, *) {     tableView.refreshControl = pullRefresh } else {     tableView.addSubview(pullRefresh) } 

Berikut source code lengkapnya :

import UIKit  class ViewController: UITableViewController {           var foods = [Food(thumb: "rendang", name: "Rendang", country: "Indonesia"),                  Food(thumb: "nasi_goreng", name: "Nasi Goreng", country: "Indonesia"),                  Food(thumb: "sushi", name: "Sushi", country: "Japan"),                  Food(thumb: "tom_yum_goong", name: "Tom Yum Goong", country: "Thailand"),                  Food(thumb: "pad_thai", name: "Pad Thai", country: "Thailand"),                  Food(thumb: "som_tam", name: "Som Tam", country: "Thailand"),                  Food(thumb: "dim_sum", name: "Dim Sum", country: "Hongkong"),                  Food(thumb: "ramen", name: "Ramen", country: "Japan"),                  Food(thumb: "peking_duck", name: "Peking Duck", country: "China"),                  Food(thumb: "massaman_curry", name: "Massaman Curry", country: "Thailand")]          let pullRefresh = UIRefreshControl()          override func viewDidLoad() {         super.viewDidLoad()         // Do any additional setup after loading the view, typically from a nib.                  // Refresh Control Properties         pullRefresh.addTarget(self, action: #selector(ViewController.pullRefresh(_:)), for: UIControlEvents.valueChanged)                  pullRefresh.tintColor = UIColor.red         pullRefresh.attributedTitle = NSAttributedString(string: "Please wait ...")                  // Add to Table View         if #available(iOS 10.0, *) {             tableView.refreshControl = pullRefresh         } else {             tableView.addSubview(pullRefresh)         }      }      override func didReceiveMemoryWarning() {         super.didReceiveMemoryWarning()         // Dispose of any resources that can be recreated.     }      func pullRefresh(_ refreshControl: UIRefreshControl) {         // do network request here                  DispatchQueue.main.asyncAfter(deadline: .now() + 3) {             self.tableView.reloadData()             refreshControl.endRefreshing()         }     }  }  struct Food {     var thumb = String()     var name = String()     var country = String() }  class CustomCell: UITableViewCell {          @IBOutlet weak var thumbImageView: UIImageView!     @IBOutlet weak var nameLabel: UILabel!     @IBOutlet weak var countryLabel: UILabel!      }  extension ViewController {     override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {         return foods.count     }          override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {                  let food = foods[indexPath.row]                  let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell                  cell.thumbImageView.image = UIImage(named: food.thumb)                  cell.nameLabel?.text = food.name         cell.countryLabel.text = food.country                  return cell              }  } 

Build dan run, maka balasannya sebagai berikut :
