我正在尝试将音频文件从服务器保存到用户手机,这样他们就不必再次下载它了。我几乎所有的东西,但我试图测试,看看音频文件是否实际播放后保存。我该怎么做?
我的代码:
var urlWebView = NSURL(string: "http://domain.com//////audios////Nightmares.wav")
var requestWebView = NSURLRequest(URL: urlWebView)
NSURLConnection.sendAsynchronousRequest(requestWebView, queue: NSOperationQueue.mainQueue(), completionHandler: {
response, data, error in
if error != nil {
println("There was an error")
} else {
let musicFile = (data: data)
var documentsDirectory:String?
var paths:[AnyObject] = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)
if paths.count > 0 {
documentsDirectory = paths[0] as? String
var savePath = documentsDirectory! + "/audio.wav"
NSFileManager.defaultManager().createFileAtPath(savePath, contents: data, attributes: nil)
self.audioPlayer = AVAudioPlayer(contentsOfURL: savePath, error: nil)
//tried to play it here but i cant since savePath is a string and not actually audio file
}
}
})
