我有这个XML By URL：

<NewDataSet>
  <Table>
    <ID>1</ID>
    <SongName>AYA LIV LIVOKIM PEL?STANKTV</SongName>
    <SongPath>http://jo.sms2tv.com/PelistankApp/Songs/song1.mp3</SongPath>

    <SongImagePath>http:\\jo.sms2tv.com\PelistankApp\Images\logo4.png</SongImagePath>
  </Table>
</NewDataSet>

我想在表格中显示歌曲名称，我没问题，现在我想要当我点击桌子上的一个单元格给我歌曲路径并把它放入NSURL，因为我想用它来播放歌曲。 1 - 我在表中显示SongName没问题。 2 - 我知道如何让AVPlayer播放歌曲只是我想点击CELL时给我一个SongPath并把它放在NSURL

中

这是我的Swift代码：

class ViewController: UIViewController, NSXMLParserDelegate, UITableViewDataSource, UITableViewDelegate
{

    @IBOutlet var tbData : UITableView?

    var parser = NSXMLParser()
    var posts = NSMutableArray()
    var elements = NSMutableDictionary()
    var element = NSString()
    var title1 = NSMutableString()
    var date = NSMutableString()

    override func viewDidLoad()
    {
     // Do any additional setup after loading the view, typically from a nib.
        super.viewDidLoad()
        self.beginParsing()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    func beginParsing()
    {

        posts = []
        parser = NSXMLParser(contentsOfURL:(NSURL(string:"http://jo.sms2tv.com/PelistankApp2/getsongs.aspx"))!)!
        parser.delegate = self
        parser.parse()

        tbData?.reloadData()
    }

对此问题的任何建议谢谢

Answer 1

这是您想要的，它可以轻点打印URL。

    /////// Table Action ( Cell clicked ) ///////

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
    {
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

        let row = indexPath.row
        print("Row: \(row)")

        print(posts.objectAtIndex(indexPath.row).valueForKey("date") as! NSString as String) //Prints the song url

    }
