我想用Swift播放一个声音。
我的代码在Swift 1.0中工作，但现在在Swift 2或更新版本中不再工作。
override func viewDidLoad() {
super.viewDidLoad()
let url:NSURL = NSBundle.mainBundle().URLForResource("soundName", withExtension: "mp3")!
do {
player = try AVAudioPlayer(contentsOfURL: url, fileTypeHint: nil)
} catch _{
return
}
bgMusic.numberOfLoops = 1
bgMusic.prepareToPlay()
if (Data.backgroundMenuPlayed == 0){
player.play()
Data.backgroundMenuPlayed = 1
}
}

这很简单，而且可以完成工作!
import AVFoundation
var player: AVAudioPlayer!
let url = Bundle.main.url(forResource: "sound_name", withExtension: "mp3")
player = try! AVAudioPlayer(contentsOf: url!)
player.play()

player.play()
如果代码没有产生任何错误，但你听不到声音-创建播放器作为一个实例:
static var player: AVAudioPlayer!
对我来说，当我做这个改变时，第一个解决方案起作用了:)
import AVFoundation
import AudioToolbox
public final class MP3Player : NSObject {
// Singleton class
static let shared:MP3Player = MP3Player()
private var player: AVAudioPlayer? = nil
// Play only mp3 which are stored in the local
public func playLocalFile(name:String) {
guard let url = Bundle.main.url(forResource: name, withExtension: "mp3") else { return }
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)
guard let player = player else { return }
player.play()
}catch let error{
print(error.localizedDescription)
}
}
}
调用这个函数
MP3Player.shared.playLocalFile(name: "JungleBook")
import AVFoundation
var player:AVAudioPlayer!
func Play(){
guard let path = Bundle.main.path(forResource: "KurdishSong", ofType: "mp3")else{return}
let soundURl = URL(fileURLWithPath: path)
player = try? AVAudioPlayer(contentsOf: soundURl)
player.prepareToPlay()
player.play()
//player.pause()
//player.stop()
}
Swift版本:5.4及以上
import AVFoundation
var player: AVAudioPlayer?
func playSound() {
guard let path = Bundle.main.path(forResource: "beep", ofType:"mp3") else {
return }
let url = URL(fileURLWithPath: path)
do {
player = try AVAudioPlayer(contentsOf: url)
player?.play()
} catch let error {
print(error.localizedDescription)
}
}
