在iOS 8和Swift 2.0中，请尝试这个，

override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
   // let the controller to know that able to edit tableView's row 
   return true
}

override func tableView(tableView: UITableView, commitEdittingStyle editingStyle UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath)  {
   // if you want to apply with iOS 8 or earlier version you must add this function too. (just left in blank code)
}

override func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]?  {
   // add the action button you want to show when swiping on tableView's cell , in this case add the delete button.
   let deleteAction = UITableViewRowAction(style: .Default, title: "Delete", handler: { (action , indexPath) -> Void in

   // Your delete code here.....
   .........
   .........
   })

   // You can set its properties like normal button
   deleteAction.backgroundColor = UIColor.redColor()

   return [deleteAction]
}

这段代码展示了如何实现删除。

#pragma mark - UITableViewDataSource

// Swipe to delete.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [_chats removeObjectAtIndex:indexPath.row];
        [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
    }
}

可选地，在初始化覆盖中，添加下面的行来显示Edit按钮项:

self.navigationItem.leftBarButtonItem = self.editButtonItem;

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
    }

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);
           }
}

对于swift4代码，首先启用编辑:

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

然后你添加删除操作到编辑委托:

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let action = UITableViewRowAction(style: .destructive, title: "Delete") { (_, index) in
        // delete model object at the index
        self.models[index.row]
        // then delete the cell
        tableView.beginUpdates()
        tableView.deleteRows(at: [index], with: .automatic)
        tableView.endUpdates()

    }
    return [action]
}

下面UITableViewDataSource将帮助你滑动删除

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    // Return YES if you want the specified item to be editable.
    return YES;
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [arrYears removeObjectAtIndex:indexPath.row];
        [tableView reloadData];
    }
}

arrayyears是一个NSMutableArray然后重新加载tableView

斯威夫特

 func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
            return true
        }

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    if editingStyle == UITableViewCellEditingStyleDelete {
        arrYears.removeObjectAtIndex(indexPath.row)
        tableView.reloadData()
    }
}
