Use TableView in MVVM structure

TableView in MVVM structure

• Create object of table view

• Set your table view data source and delegates to your view model class object
  
  fileprivate let homeViewModelObject = HomeViewModel() HomeTableView.delegate = homeViewModelObject HomeTableView.dataSource = homeViewModelObject

  fileprivate let homeViewModelObject = HomeViewModel() HomeTableView.delegate = homeViewModelObject HomeTableView.dataSource = homeViewModelObject

• Create extension of your view model and define data source and delegates of table view
  
  extension HomeViewModel : UITableViewDelegate , UITableViewDataSource { }

  extension HomeViewModel : UITableViewDelegate ,  UITableViewDataSource  {   }

• Implement table view functions
  
  func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return items.count } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: HomeProductTableViewCell.identifier) as! HomeProductTableViewCell return cell }

  func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {         return items.count }   func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {     let cell = tableView.dequeueReusableCell(withIdentifier: HomeProductTableViewCell.identifier) as! HomeProductTableViewCell     return cell }

• After getting data in items array you can use callback or Notification to tell your controller to reload the table view.Define notification in your view model class
  
  NotificationCenter.default.post(name: NSNotification.Name(rawValue: "load"), object: nil)

  1	NotificationCenter.default.post(name: NSNotification.Name(rawValue: "load"), object: nil)

• Use Notification in your controller class
  
  NotificationCenter.default.addObserver(self, selector: #selector(loadList), name: NSNotification.Name(rawValue: "load"), object: nil) func loadList(notification: NSNotification){ self.HomeTableView.reloadData() }

  NotificationCenter.default.addObserver(self, selector: #selector(loadList), name: NSNotification.Name(rawValue: "load"), object: nil)      func loadList(notification: NSNotification){      self.HomeTableView.reloadData()   }
