如何从文档目录中访问音频文件？

Question

我有一个存储在文档目录中的音频文件，现在我需要获取该音频文件并进行一些加密/解密。 我想要这样：

let audiofile = get audio file from document directory // This is what i want

encrypt(audiofile)// I have AES technique, This is not my question.

Answer 1

这很简单!!!!

就像下面的代码::

var paths: [AnyObject] = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)

let audiofilePath = paths[0].stringByAppendingString("/myaudio.mp3")

//Write name of your audio at **myaudio.mp3**

//now you can use anywhere audiofilePath as String like

let audiourl : NSURL = NSURL((fileURLWithPath: audiofilePath))

//or you can make asset like

let assets = AVAsset(URL: NSURL(fileURLWithPath: audiofilePath))

享受编码，如果有任何帮助，只需问我..
