UITableViewRowAction image for title

Question

I made a custom UITableViewRowAction. Now I\'d like to add an image instead of the text. I know that it\'s possible but don\'t know how to do it. Does someone of you knows

Answer 1

I made this simple UITableViewRowAction category, in order to set the icon for my actions. You can set the image, the background color, the cell height (to manage dynamic cells) and the icon size in percentage.

extension UITableViewRowAction {

  func setIcon(iconImage: UIImage, backColor: UIColor, cellHeight: CGFloat, iconSizePercentage: CGFloat)
  {
    let iconHeight = cellHeight * iconSizePercentage
    let margin = (cellHeight - iconHeight) / 2 as CGFloat

    UIGraphicsBeginImageContextWithOptions(CGSize(width: cellHeight, height: cellHeight), false, 0)
    let context = UIGraphicsGetCurrentContext()

    backColor.setFill()
    context!.fill(CGRect(x:0, y:0, width:cellHeight, height:cellHeight))

    iconImage.draw(in: CGRect(x: margin, y: margin, width: iconHeight, height: iconHeight))

    let actionImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    self.backgroundColor = UIColor.init(patternImage: actionImage!)
  }
}
