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
    }

当你移除tableview的一个单元格时，你也必须移除索引x处的数组对象。

我认为你可以用滑动手势来移除它。 表视图将调用委托:

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        //add code here for when you hit delete
        [dataSourceArray removeObjectAtIndex:indexPath.row];
    }    
}

移除物体后。你需要重新加载tableview。 在代码中添加以下代码行:

[tableView reloadData];

之后，就成功删除了该行。当您重新加载视图或向DataSource添加数据时，对象将不再存在。

对于所有其他的，库尔茨的答案是正确的。

我只是想提醒你，如果你想从DataSource数组中删除对象，委托函数是不够的。

我希望我对你有所帮助。

我知道这是一个老问题，但是@Kurbz的答案只需要Xcode 6.3.2和SDK 8.3

我需要添加[tableView beginUpdates]和[tableView endpdates](感谢@bay。phillips)

// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle: (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    // Open "Transaction"
    [tableView beginUpdates];

    if (editingStyle == UITableViewCellEditingStyleDelete) {
        // your code goes here
        //add code here for when you hit delete
        [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
     }

    // Close "Transaction"
    [tableView endUpdates];
}

Swift 2.2:

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

override func tableView(tableView: UITableView,
    editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
    let delete = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "DELETE"){(UITableViewRowAction,NSIndexPath) -> Void in

    print("Your action when user pressed delete")
}
let edit = UITableViewRowAction(style: UITableViewRowActionStyle.Normal, title: "EDIT"){(UITableViewRowAction,NSIndexPath) -> Void in

    print("Your action when user pressed edit")
}
    return [delete, block]
}

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)
    }
}

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]
}
