获取NSMutableArray的ID

Question

我有一个名为timelineData的NSMutableArray

    override func tableView(tableView: UITableView?, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath?) {
    if editingStyle == .Delete {
        let idForDelete:AnyObject! = timelineData.objectAtIndex(indexPath!.row)
        println(idForDelete)
    }
}

当我在调试器中执行此代码时，我会收到：

<ClassName:gGYnstSagn:(null)> {
    content = "iosdfjgijdsiofgjisd oifg jiosdfgi sdfig j";
    title = ahgahahah;
    userid = "6rOBfCHtcu";
}

我如何获得ID＆＃34; gGYnstSagn＆＃34; ClassName？
