title: How can i stop my tableView cell from reusing the button inside it?
body: <p>I have a function inside a protocol that takes a TableViewcell as an argument.  </p>
  
  <pre><code>protocol GoingButtonDelegate {
      func goingButtonPressed(cell: TableViewCell)
  }
  
  class TableViewCell: UITableViewCell {
      // Outlets
      @IBOutlet weak var goingButton: UIButton!
  
      var delegate: GoingButtonDelegate?
  
      @IBAction func goingButtonTapped(_ sender: Any) {
          delegate?.goingButtonPressed(cell: self)  
      }
  </code></pre>
  
  <p>I then go over to my ViewController and implement the delegate and it's function, which is to change the image of a button when tapped. The "goingSelected" is a green image and the "goingDeselected" is a red image.</p>
  
  <p>This all works out fine, when tapped the button of a cell goes from red to green and vice versa. However, when the cell gets reused, the button state of the cell persists and gets reused for the new row that enters view. Is there any way to stop this from happening?</p>
  
  <pre><code> extension ViewController: GoingButtonDelegate {
      func goingButtonPressed(cell: TableViewCell) {
          cell.goingButton.isSelected = !cell.goingButton.isSelected
  
          if cell.goingButton.isSelected == true {
              cell.goingButton.setImage(UIImage(named: "goingSelected"), for: UIControlState.selected)
          } else if cell.goingButton.isSelected == false {
              cell.goingButton.setImage(UIImage(named: "goingDeselected"), for: UIControlState.normal)
          }
      }
  }
  </code></pre>
