Apple 引入了灵活的方式来声明行操作，并带来巨大好处.

iOS 11.0

Swift

Apple introduced flexible way to declare row actions with great benefits.

extension ViewController: UITableViewDelegate {
  func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let askAction = UIContextualAction(style: .normal, title: nil) { action, view, complete in
      print("Ask!")
      complete(true)
    }

    // here set your image and background color
    askAction.image = IMAGE
    askAction.backgroundColor = .darkGray

    let blockAction = UIContextualAction(style: .destructive, title: "Block") { action, view, complete in
      print("Block")
      complete(true)
    }

    return UISwipeActionsConfiguration(actions: [blockAction, askAction])
  }

  func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    cell.textLabel?.text = "row: (indexPath.row)"
  }
}

示例:

需要将UIImage设置为row action的backgroundColor，具体通过:

You need to set UIImage to backgroundColor of row action, concretely by:

UIColor(patternImage: UIImage(named: "IMAGE_NAME"))

目标-C:

[UIColor colorWithPatternImage:[UIImage imageNamed:@"IMAGE_NAME"]];
