代码帮助播放多个声音（目标c）到Swift（代码7）

正在尝试将下面的代码

objective-c

转换为

Swift

，请帮助我这样做，或者使用新代码帮助我播放多个声音***

- (IBAction)pushButton {    
      NSString *path = [[NSBundle mainBundle] pathForResouce:@"ring" ofType:@"mp3"];
      if(theAudio) [theAudio release];
      theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
      theAudio.delegate = self;
      [theAudio play];       
}

- (IBAction)pushButton1 {
      NSString *path = [[NSBundle mainBundle] pathForResouce:@"amaze" ofType:@"mp3"];
      if(theAudio) [theAudio release];
      theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
      theAudio.delegate = self;
      [theAudio play];
}

Swift版本：-

let path : String = NSBundle.mainBundle().pathForResource("ring", ofType: "mp3")!
if(theAudio){
    theAudio.release()
}
theAudio = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath:path), error: &err)
audioPlayer.delegate = self
audioPlayer.play()


func pushButton1(){
    let path : String = NSBundle.mainBundle().pathForResource("amaze", ofType: "mp3")!
    if(theAudio){
        theAudio.release()
    }
    theAudio = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath:path), error: &err)
    audioPlayer.delegate = self
    audioPlayer.play()

}

这不是编码服务。至少表现出你这边的努力！我从过去两周（每天5小时）就开始这样做，只是为了让它发挥作用。你能做什么？发帖！
