从NSFileManager获取文档目录中的文件。我得到了一组文件名，我可以将它们传递给另一个控制器。仍然我想从我的UITableViewCell的特定文件通过NSURL，因为我传递了这些文件的名称。我的文件是MP3。请帮帮我。如何在swift中从文档目录中的特定文件获取NSURL
var listOfMP3Files: Array<String!>? // for Cell data
func fetchFilesFromFolder() {
var fileManager = NSFileManager.defaultManager()
var folderPathURL = fileManager.URLsForDirectory(NSSearchPathDirectory.DocumentDirectory, inDomains: NSSearchPathDomainMask.UserDomainMask)[0] as! NSURL
var documentsContent = fileManager.contentsOfDirectoryAtPath(folderPathURL.path!, error: nil)
println(documentsContent)
if var directoryURLs = fileManager.contentsOfDirectoryAtURL(folderPathURL, includingPropertiesForKeys: nil, options: NSDirectoryEnumerationOptions.SkipsHiddenFiles, error: nil) {
println(directoryURLs)
var mp3Files = directoryURLs.map(){ $0.lastPathComponent }.filter(){ $0.pathExtension == "mp3" }
listOfMP3Files = mp3Files
println(mp3Files)
}
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
var playerVC = (segue.destinationViewController as! UINavigationController).topViewController as! AVPlayerVC
var indexPath = tableView.indexPathForSelectedRow()
var objectForPass = listOfMP3Files![indexPath!.row] // default
if segue.identifier == "listenMusic" {
playerVC.object = objectForPass
}
}
UPDATE：
我更新了我的代码，我可以得到jpg格式的文件。但我不知道如何获得mp3文件。
我更新的代码
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
var playerVC = (segue.destinationViewController as! UINavigationController).topViewController as! PlayMusicViewController
var indexPath = tableView.indexPathForSelectedRow()
var objectForPass = listOfMP3Files![indexPath!.row] // default
//
var path = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0] as? String
var getImage = path?.stringByAppendingPathComponent(objectForPass)
var image = UIImage(contentsOfFile: getImage!)
if segue.identifier == "listenMusic" {
playerVC.musicFile = objectForPass
playerVC.end = image
}
}
UPDATE2 我编辑我的代码，我可以通过NSURL的MP3文件，而在另一个UIViewController我可以发挥他们。
下面有一个编辑的代码
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
var playerVC = (segue.destinationViewController as! UINavigationController).topViewController as! PlayMusicViewController
var indexPath = tableView.indexPathForSelectedRow()
var objectForPass = listOfMP3Files![indexPath!.row] // default
//
/* var path = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0] as? String
var getImage = path?.stringByAppendingPathComponent(objectForPass)
var image = UIImage(contentsOfFile: getImage!) */
//
var fileM = NSFileManager.defaultManager()
var wayToFile = fileM.URLsForDirectory(NSSearchPathDirectory.DocumentDirectory, inDomains: NSSearchPathDomainMask.UserDomainMask)
var passMusicFileURL: NSURL?
if let documentPath: NSURL = wayToFile.first as? NSURL {
let musicFile = documentPath.URLByAppendingPathComponent(objectForPass)
println(musicFile)
passMusicFileURL = musicFile
}
if segue.identifier == "listenMusic" {
// playerVC.musicFile = objectForPass
playerVC.end = passMusicFileURL
}
}
