你所要做的就是启用这两个功能:

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {

    return true

}

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

    if editingStyle == UITableViewCellEditingStyle.delete {
        tableView.reloadData()
    }

}

同样，这也可以通过以下方法在SWIFT中实现

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    if (editingStyle == UITableViewCellEditingStyle.Delete){
        testArray.removeAtIndex(indexPath.row)
        goalsTableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Automatic)
    }
}

对于Swift，只需要写这段代码

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if editingStyle == .Delete {
            print("Delete Hit")
        }
}

对于Objective C，只需编写以下代码

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
       if (editingStyle == UITableViewCellEditingStyleDelete) {           
            NSLog(@"index: %@",indexPath.row);
           }
}

要在滑动中删除单元格，UITableView有两个内置的方法。把这个方法写在TableView dataSource扩展中。

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
  let delete = deleteProperty(at: indexPath)
  return UISwipeActionsConfiguration(actions: [delete])
}

// Declare this method in UIViewController Main and modify according to your need

func deleteProperty(at indexpath: IndexPath) -> UIContextualAction {
  let action = UIContextualAction(style: .destructive, title: "Delete") { (action, view, completon) in
    self.yourArray.remove(at: indexpath) // Removing from array at selected index

    completon(true)
    action.backgroundColor = .red //cell background color
  }
  return action
}

SWIFT 5:适用于iOS 13+

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
        return true
  }
    
    
 func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let deleteAction = UIContextualAction(style: .destructive, title: "Delete") {  (contextualAction, view, boolValue) in
            //Code I want to do here
        }
        
        let editAction = UIContextualAction(style: .destructive, title: "Edit") {  (contextualAction, view, boolValue) in
            //Code I want to do here
        }
        
        let swipeActions = UISwipeActionsConfiguration(actions: [deleteAction, editAction])
        
        return swipeActions
    }
