iOS sending audio file to web server - ios

Question

I currently building an iPhone app with Swift and I want to send audio files from my app to my web server. I am currently using MPMediaPickerController, which allows me to select an audio file within my app but once I select the file, it keeps telling me:
ipod-library://item/item.mp3?id=12341234
and I am not able to send the file to my web server. I need to send the audio file to my web server in NSData format. Can anyone shine a light into:
1) What I may be doing wrong or,
2) another way to send the audio files?

Answer 1

import AssetsLibrary,
import AVFoundation,
import MediaPlayer,
var soundFileURL:URL!,
var audio_data: Data? = nil**
func mediaPicker(_ mediaPicker: MPMediaPickerController, didPickMediaItems mediaItemCollection: MPMediaItemCollection)
{
let item = mediaItemCollection.items[0] as? MPMediaItem ?? MPMediaItem()
let url: URL? = item.value(forProperty: MPMediaItemPropertyAssetURL) as? URL
exportiTunesSong(assetURL: url!)
{
(response) in
print(response ?? "responce")
}
let songTitle: String = item.value(forProperty: MPMediaItemPropertyTitle) as! String
lbl_for_file_name.text = songTitle
self.dismiss(animated: true, completion: nil)
}
func mediapicker()
{
let mediaPicker = MPMediaPickerController(mediaTypes: .music)
mediaPicker.delegate = self
present(mediaPicker, animated: true, completion: {})
}
func mediaPickerDidCancel(_ mediaPicker: MPMediaPickerController)
{
print("User selected Cancel tell me what to do")
self.dismiss(animated: true, completion: nil)
mediaPicker.dismiss(animated: true) { _ in }
}
func exportiTunesSong(assetURL: URL, completionHandler: #escaping (_ fileURL: URL?) -> ()) {
let songAsset = AVURLAsset(url: assetURL, options: nil)
let exporter = AVAssetExportSession(asset: songAsset, presetName: AVAssetExportPresetAppleM4A)
exporter?.outputFileType = "com.apple.m4a-audio"
exporter?.metadata = songAsset.commonMetadata
let filename = AVMetadataItem.metadataItems(from: songAsset.commonMetadata, withKey: AVMetadataCommonKeyTitle, keySpace: AVMetadataKeySpaceCommon)
var songName = "Unknown"
if filename.count > 0 {
songName = ((filename[0] as AVMetadataItem).value?.copy(with: nil) as? String)!
}
//Export mediaItem to temp directory
exportURL = URL(fileURLWithPath: NSTemporaryDirectory())
.appendingPathComponent(songName)
.appendingPathExtension("m4a")
exporter?.outputURL = exportURL
do
{
self.audio_data = try Data.init(contentsOf: exportURL!)
print("here audio data is \(self.audio_data!)")
} catch {
print(error)
}
}
P.S use Audio_data to send or upload server side using Alamofire

Answer 2

I think this answer will help you:
Sending audio from a Swift App to PHP Server, and somewhere the audio is lost
Especially should pay attention to this section:
let boundary = "--------14737809831466499882746641449----"
let beginningBoundary = "--\(boundary)"
let endingBoundary = "--\(boundary)--"
let contentType = "multipart/form-data;boundary=\(boundary)"
So for audio file uploads that's also important.
