所以我有一个AVAudioPlayer,有时它工作得很好,但有时它会输出错误“Error Domain = NSOSStatusErrorDomain Code = 1954115647”(null)“”.这是代码：
override func viewDidLoad() {
super.viewDidLoad()
downloadFileFromURL(url: URL(string: mainPreviewURL)!)
}
func downloadFileFromURL(url: URL) {
var downloadTask = URLSessionDownloadTask()
downloadTask = URLSession.shared.downloadTask(with: url,completionHandler: {
customURL,response,error in
self.play(url: customURL!)
})
downloadTask.resume()
}
func play(url: URL) {
do {
player = try AVAudioPlayer(contentsOf: url)
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
player!.prepareToPlay()
player!.play()
} catch {
print(error)
}
}
解决方法
使do语句中的代码如下所示：
let songData = try NSData(contentsOfURL: songURL!,options: NSDataReadingOptions.mappedIfSafe)
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer(data: songData!,fileTypeHint: AVFileTypeMpegLayer3)
player!.prepareToPlay()
player!.play()
