[英]Read data from file swift
I was trying to read a file xyz.m4a
and trying to play it.我试图读取文件
xyz.m4a
并尝试播放它。 But I have an error但我有一个错误
2018-04-24 18:11:20.010927+0530 Demo[10807:690526] NSURLConnection finished with error - code -1002
2018-04-24 18:11:20.327008+0530 Demo[10807:688427] CFURLCopyResourcePropertyForKey failed because it was passed an URL which has no scheme
Error: The file “xyz.m4a” couldn’t be opened.
Here is my code:这是我的代码:
func audioMethod() {
let fileName = "xyz.m4a",
audioFile = getDocumentsURL().appendingPathComponent(fileName)
if !FileManager.default.fileExists(atPath: audioFile.path) {
print("We have no file !!!!!")
}
do {
let audioData = try Data(contentsOf: audioFile)
if audioPlayer == nil {
audioPlayer = try AVAudioPlayer.init(data: audioData, fileTypeHint: "m4a")
}
audioPlayer?.play()
} catch let error {
print("Error: " + error.localizedDescription)
}
}
func getDocumentsURL() -> URL {
let urlStr = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first
let url = URL(string: urlStr!)
return url!
}
If I pass that URL
direct in AVAudioPlayer
as AVAudioPlayer.init(contentsOf: audioFile)
then it works fine.如果我直接在
AVAudioPlayer
将该URL
作为AVAudioPlayer.init(contentsOf: audioFile)
传递,那么它工作正常。
I have tried everything.我已经尝试了一切。 But nothing works.
但没有任何作用。 Please let me know what is wrong with my code.
请让我知道我的代码有什么问题。
if let path = Bundle.main.path(forResource: "videoplayback", ofType: "mp4"){
let video = AVPlayer(url: URL(fileURLWithPath:path))
let videoPlayer = AVPlayerViewController()
videoPlayer.player = video
present(videoPlayer,animated: true,completion: {
video.play()
})
}
Add that Video in File Explorer在文件资源管理器中添加该视频
Then try with above code然后尝试使用上面的代码
