Ios 创建一个随机音频声音发生器

谢谢你的回复

我正试图制作一个程序，当我按下一次按钮时，两个随机的声音将播放。我可以让随机声音播放，如果我按下按钮，但我看，如果我按下按钮，随机声音将发挥不同的每一次

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var player: AVAudioPlayer = AVAudioPlayer()

    var sounds = ["sound1", "sound2", "sound3"]

    override func viewDidLoad() {
        super.viewDidLoad()  

    }

    override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {
        if event!.subtype == UIEventSubtype.motionShake {


            let randomNumber = Int(arc4random_uniform(UInt32(sounds.count)))
            let fileLocation = Bundle.main.path(forResource: sounds[randomNumber], ofType: "mp3")
            var error: NSError? = nil
            do { try player = AVAudioPlayer(contentsOf: URL(fileURLWithPath: fileLocation!))
            player.play()
            } catch {}           
        }
    }

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

我可以将这些声音粘贴在一起，按照我想要的顺序来听，但我希望swift生成这些声音

我想到了AVqueplayer，使其成为一个播放列表。我在想，这可以像一个比喻中的一对骰子。例如，如果我掷骰子，随机的声音就会出现

我还是一个新手，我试着自己解决这个问题，因为它看起来很简单，但我现在没有选择了

这是我到目前为止得到的。当我每次按下按钮时，这将播放随机声音

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var player: AVAudioPlayer = AVAudioPlayer()

    var sounds = ["sound1", "sound2", "sound3"]

    override func viewDidLoad() {
        super.viewDidLoad()  

    }

    override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {
        if event!.subtype == UIEventSubtype.motionShake {


            let randomNumber = Int(arc4random_uniform(UInt32(sounds.count)))
            let fileLocation = Bundle.main.path(forResource: sounds[randomNumber], ofType: "mp3")
            var error: NSError? = nil
            do { try player = AVAudioPlayer(contentsOf: URL(fileURLWithPath: fileLocation!))
            player.play()
            } catch {}           
        }
    }

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

使用相同的代码，并添加第二个具有匹配文件位置的随机数，将允许声音背靠背播放，两者都是随机的：

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var player: AVAudioPlayer = AVAudioPlayer()

    var sounds = ["sound1", "sound2", "sound3"]

    override func viewDidLoad() {
        super.viewDidLoad()  

    }

    override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {
        if event!.subtype == UIEventSubtype.motionShake {


            let randomNumber1 = Int(arc4random_uniform(UInt32(sounds.count)))
            let randomNumber2 = Int(arc4random_uniform(UInt32(sounds.count)))
            let fileLocation1 = Bundle.main.path(forResource: sounds[randomNumber1], ofType: "mp3")
            let fileLocation2 = Bundle.main.path(forResource: sounds[randomNumber2], ofType: "mp3")
            //var error: NSError? = nil
            do {
                try player = AVAudioPlayer(contentsOf: URL(fileURLWithPath: fileLocation1!))
                player.play()
                try player = AVAudioPlayer(contentsOf: URL(fileURLWithPath: fileLocation2!))
                player.play()
            } catch {}           
        }
    }

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