Question

我有两个XML网址。第一个网址在SongName上显示Table，第二个网址显示SongPath。当我点击表格上的SongName时，它会转到第二个网址中的SongPath。这是 table。您可以在代码中看到SongName网址。

这是XML：

<NewDataSet>
  <Table>
    <SongName>AYA LIV LIVOKIM PEL?STANKTV</SongName>
  </Table>
  <Table>
    <SongName>DîLAN PPP PELISTANK</SongName>
  </Table>
  <Table>
    <SongName>KARIN BAL DAGRIM</SongName>
  </Table>
  <Table>
    <SongName>RUKEN WERE CANE</SongName>
  </Table>
</NewDataSet>

这是SongPath的第二个网址：

这就是XML：

<NewDataSet>
  <Table>
    <SongPath>http://jo.sms2tv.com/PelistankApp/Songs/song1.mp3</SongPath>
  </Table>
  <Table>
    <SongPath>http://jo.sms2tv.com/PelistankApp/Songs/song2.mp3</SongPath>
  </Table>
  <Table>
    <SongPath>http://jo.sms2tv.com/PelistankApp/Songs/song3.mp3</SongPath>
  </Table>
  <Table>
    <SongPath>http://jo.sms2tv.com/PelistankApp/Songs/song4.mp3</SongPath>
  </Table>
</NewDataSet>

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/PelistankApp/default.aspx"))!)!
        parser.delegate = self
        parser.parse()

        tbData?.reloadData()
    }

请提出任何建议。我可以制作MP3播放器没问题，我只是想要它，这样当我点击表格中的一个单元格时，它将播放第二个XML URL中同一行的歌曲。

Answer 1

首先解析您的两个API并将歌曲名称和歌曲URL存储在一个数组中。并且只要你想要一次又一次地解析它，就可以访问它。

这个答案是使用SWXMLHash
进行解析

您可以使用Alamofire发出HTTP请求

let xml = SWXMLHash.parse(data!)
       for elem in xml["NewDataSet"]["Table"] {

            print(elem["SongName"].element?.text) //PRINT SONG NAME 
        }

有关XML解析的更多信息，我已经answered

//这是你想要的

    /////// 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

    }
