如何滑动删除表格单元格以进行解析？

Question

I am able to delete the row in my tableview. But I would like to do the same for the information on parse.com. any suggestions as to how I could go about this?

override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {


    if editingStyle == UITableViewCellEditingStyle.Delete {
        // Delete the row from the data source
        tableView.beginUpdates()
        usernames.removeAtIndex(indexPath.row)
        tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
        tableView.endUpdates()
    } else if editingStyle == .Insert {
        // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
    }    
}

假设usernames是PFObject（也许是PFUser）的数组，那么您只需要在tableView.beginUpdates()之后添加usernames[indexPath.row].deleteInBackground() tableView.beginUpdates()
