这是一个教你怎样播放音频的例子：

第一种标准的方法是：

varaudioPlayer:AVAudioPlayer!

// To find file path of audio

ifletfilePath =NSBundle.mainBundle().pathForResource("movie_quote", ofType:"mp3"){

// To find file path url from file path

letfilePathUrl =NSURL.fileURLWithPath(filePath)

do{

// init audioPlayer using file path url

audioPlayer=tryAVAudioPlayer(contentsOfURL: filePathUrl, fileTypeHint:nil)

}catch{

print("the filePathUrl is empty")

}

}else{

print("the filePath is empty")

}

audioPlayer.play()

第二种简化的方法是

varaudioPlayer:AVAudioPlayer!

// To find file path of audio

ifletfilePath =NSBundle.mainBundle().pathForResource("movie_quote", ofType:"mp3"){

// To find file path url from file path

letfilePathUrl =NSURL.fileURLWithPath(filePath)

audioPlayer=try!AVAudioPlayer(contentsOfURL:receivedAudio.filePathUrl,fileTypeHint:nil)}else{

print("the filePath is empty")

}

audioPlayer.play()
