使用AVFoundation随机播放mp3

Question

    override func viewDidAppear(animated: Bool) {

    let fileLocation = NSBundle.mainBundle().pathForResource(self.navigationItem.title, ofType: "mp3", inDirectory: "Story")!

    try! player = AVAudioPlayer(contentsOfURL: NSURL (string: fileLocation as String)!)

    player.play()

I have a folder with 4 MP3s, and a cell list accessing each one of those 4 MP3s. Why is it playing the same MP3 again and again for each of those cells?

It is not even the first one from that folder, it is the last one!

Answer 1

我想您的导航项目标题是一个常量值。

Answer 2

Is this in a UITableView? If so, try doing it through the didselectviewatindexPath from UITableViewDelegate. Find the indexPath that is clicked and use that to play the mp3 for each cell.
