List files in iTunes shared folder using Swift - xcode

Question

I would like to list all files in my iTunes shared folder in a 'Table View' using Swift.
I check on Google and nobody talk about it, it look like it's a uncommon need, so if anyone can help it would be really helpful.
EDIT: I found three links talking about it but in Objective-C, I have no experience in this language. If someone understand this, here are the links.

Answer 1

Based on this objective-C tutorial http://mobiforge.com/design-development/importing-exporting-documents-ios, I created three methods: listFilesFromDocumentsFolder which returns a list of the names of all documents I have in the apps iTunes shared folder and loadFileFromDocumentsFolder which loads the url for a given filename and passes the url to handleDocumentOpenUrl to load the file on a UIWebView. Find below the three methods.
You can also download the project from github: https://github.com/Euniceadu/Load-Shared-Documents
listFilesFromDocumentsFolder
func listFilesFromDocumentsFolder() {
var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
var documentsDirectory : String;
documentsDirectory = paths[0] as String
var fileManager: NSFileManager = NSFileManager()
var fileList: NSArray = fileManager.contentsOfDirectoryAtPath(documentsDirectory, error: nil)!
var filesStr: NSMutableString = NSMutableString(string: "Files in Documents folder \n")
for s in fileList {
filesStr.appendFormat("%#", s as String)
}
self.displayAlert(filesStr)
}
loadFileFromDocumentsFolder
func loadFileFromDocumentsFolder(fileName: String) {
var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
var documentsDirectory : String;
documentsDirectory = paths[0] as String
var filePath: String = documentsDirectory.stringByAppendingPathComponent(fileName);
var fileUrl: NSURL = NSURL(fileURLWithPath: filePath);
self.handleDocumentOpenURL(fileUrl)
}
handleDocumentOpenUrl
func handleDocumentOpenURL(url: NSURL) {
var requestObj = NSURLRequest(URL: url)
webView.userInteractionEnabled = true
webView.loadRequest(requestObj)
}
Hope this helps.
