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
}
}

文件Sfx.swift
import AVFoundation
public let sfx = Sfx.shared
public final class Sfx: NSObject {
static let shared = Sfx()
var apCheer: AVAudioPlayer? = nil
// etc
private override init() {
guard let s = Bundle.main.path(forResource: "cheer", ofType: "mp3") else { print("Sfx woe"); return }
do { apCheer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: s)) } catch { print("Sfx woe"); return }
// etc
}
func cheer() { apCheer?.play() }
func plonk() { apPlonk?.play() }
func crack() { apCrack?.play() }
// etc
}
只要吃一个……
var apCheer: AVAudioPlayer? = nil
对于你的每一个音频刺。所以你可能有5 20 10等等。
对于每一个，简单地复制/粘贴两行初始化代码:
guard let s = Bundle.main.path(forResource: "cheer", ofType: "mp3") else { return print("Sfx woe") }
do { apCheer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: s)) } catch { return print("Sfx woe") }
然后，在任何地方，任何代码，任何文件，你都可以:
sfx.cheer()
sfx.crack()

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()
}
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()
斯威夫特3
import AVFoundation
var myAudio: AVAudioPlayer!
let path = Bundle.main.path(forResource: "example", ofType: "mp3")!
let url = URL(fileURLWithPath: path)
do {
let sound = try AVAudioPlayer(contentsOf: url)
myAudio = sound
sound.play()
} catch {
//
}
//If you want to stop the sound, you should use its stop()method.if you try to stop a sound that doesn't exist your app will crash, so it's best to check that it exists.
if myAudio != nil {
myAudio.stop()
myAudio = nil
}
对于Swift 3:
import AVFoundation
/// **must** define instance variable outside, because .play() will deallocate AVAudioPlayer
/// immediately and you won't hear a thing
var player: AVAudioPlayer?
func playSound() {
guard let url = Bundle.main.url(forResource: "soundName", withExtension: "mp3") else {
print("url not found")
return
}
do {
/// this codes for making this app ready to takeover the device audio
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
/// change fileTypeHint according to the type of your audio file (you can omit this)
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3)
// no need for prepareToPlay because prepareToPlay is happen automatically when calling play()
player!.play()
} catch let error as NSError {
print("error: \(error.localizedDescription)")
}
}
本地资产的最佳实践是将其放在资产中。Xcassets然后像这样加载文件:
func playSound() {
guard let url = Bundle.main.url(forResource: "soundName", withExtension: "mp3") else {
print("url not found")
return
}
do {
/// this codes for making this app ready to takeover the device audio
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
/// change fileTypeHint according to the type of your audio file (you can omit this)
/// for iOS 11 onward, use :
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)
/// else :
/// player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3)
// no need for prepareToPlay because prepareToPlay is happen automatically when calling play()
player!.play()
} catch let error as NSError {
print("error: \(error.localizedDescription)")
}
}
