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()
    }

}

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;

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);
           }
}

- (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];
        [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
    }    
}

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let delete = UITableViewRowAction(style: .destructive, title: "delete") { (action, indexPath) in
        // delete item at indexPath
    tableView.deleteRows(at: [indexPath], with: .fade)

    }
    return [delete]
}
