Swift 2：AVAudioPlayers一次播放多个声音

嘿.嘿

我一直在寻找,试图找到解决这个问题的方法,但基本上没有解决方案.

我迫切需要一种方法来实例化并随时播放声音,而不会切断任何其他声音.我知道AVAudioPlayer一次只能播放一个声音,所以我想弄清楚如何制作AVAudioPlayers的动态数组,我可以在需要播放声音的任何时候添加它.我在本网站上从不同的答案得到的当前代码是：

func Sound(sound: String) {
    do {
        if let bundle = NSBundle.mainBundle().pathForResource(sound,ofType: "wav") {
            let alertSound = NSURL(fileURLWithPath: bundle)
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient)
            try AVAudioSession.sharedInstance().setActive(true)
            try audioPlayer = AVAudioPlayer(contentsOfURL: alertSound)
            audioPlayer.preparetoPlay()
            audioPlayer.play()
        }
    } catch {
        print(error)
    }


}

遗憾的是,这不起作用.它播放声音,但停止播放任何其他声音.

I’ve also tried the code from here,but I’m having the same problem the asker is having,and there’s no solution.

基本上,我只需要一个与Swift 2同步的代码片段,这样我就可以播放声音,而不会删除正在播放的任何其他声音.即使两次声音效果相同.

解决方法

这个问题听起来更像是你对Swift数据结构并不十分了解,但这里有一个简单的片段可以帮助你：

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var arrayOfPlayers = [AVAudioPlayer]()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view,typically from a nib.
        sound("tester")
        let delayTime = dispatch_time(disPATCH_TIME_Now,Int64(2 * Double(NSEC_PER_SEC)))
        dispatch_after(delayTime,dispatch_get_main_queue()) {
            self.sound("tester")
        }

    }

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

    func sound(sound: String) {
        do {
            if let bundle = NSBundle.mainBundle().pathForResource(sound,ofType: "wav") {
                let alertSound = NSURL(fileURLWithPath: bundle)
                try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient)
                try AVAudioSession.sharedInstance().setActive(true)
                let audioPlayer = try AVAudioPlayer(contentsOfURL: alertSound)
                arrayOfPlayers.append(audioPlayer)
                arrayOfPlayers.last?.preparetoPlay()
                arrayOfPlayers.last?.play()
            }
        } catch {
            print(error)
        }


    }

}
