UITableViewCell checkmark to be toggled on and off when tapped

Question

I'm working on a tableview

I want to be able to tap on each cell and when tapped, it displays a checkmark on the cell

Now I have some code that makes this work:

// checkmarks when tapped  func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {     let section = indexPath.section     let numberOfRows = tableView.numberOfRowsInSection(section)     for row in 0..<numberOfRows {         if let cell = tableView.cellForRowAtIndexPath(NSIndexPath(forRow: row, inSection: section)) {             cell.accessoryType = row == indexPath.row ? .Checkmark : .None         }     } } 

but this code only selects 1 cell inside a section (I have 5 sections)

I need it to select any cell anywhere

Also when I drag my screen up and down I lose by checkmark

viewcontroller.swift

Swift > 3.0

func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {     if let cell = tableView.cellForRow(at: indexPath) {         cell.accessoryType = .none     } } func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {     if let cell = tableView.cellForRow(at: indexPath) {         cell.accessoryType = .checkmark      } } 

I solved by using two Swift functions: the didSelectRowAtIndexPath and the didDeselectRowAtIndexPath.

override func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {     if let cell = tableView.cellForRowAtIndexPath(indexPath) {         cell.accessoryType = .None     } } override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {     if let cell = tableView.cellForRowAtIndexPath(indexPath) {         cell.accessoryType = .Checkmark      } } 

To make this work properly, add a line of code to your cellForRowAtIndexPath function to select a row when the table view is drawn on the screen, otherwise the didDeselectRowAtIndexPath will not be called the first time you select another row. Like so:

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {     let cell = tableView.dequeueReusableCellWithIdentifier("cellData", forIndexPath: indexPath)      if (some condition to initially checkmark a row)         cell.accessoryType = .Checkmark         tableView.selectRowAtIndexPath(indexPath, animated: false, scrollPosition: UITableViewScrollPosition.Bottom)     } else {         cell.accessoryType = .None     }      return cell }
