Trying to record audio file is not being saved

#1

My code is trying to record sound and display it on a tableview. However it appears that the audio is not being saved. I am seeing this message in my log file.

    2019-01-13 11:11:07.926903-0500 recrod sound[2902:31076] 317: ca_debug_string: inPropertyData == NULL

I do not know what that means. It appears that no audio is being recorder and when i click on it in the tableview it is not working. I am trying to follow this tutorial https://www.youtube.com/watch?v=CrLbuzM9IDs

           import UIKit;import AVFoundation

    class ViewController: UIViewController, AVAudioRecorderDelegate, UITableViewDataSource, UITableViewDelegate {
var recordingSessioin: AVAudioSession!
var audioRecorder: AVAudioRecorder!
var aduioPlayer : AVAudioPlayer!

@IBOutlet var mytableVie3w : UITableView!

var numberOfRecords = 0
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return numberOfRecords
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for : indexPath)
    cell.textLabel?.text = String(indexPath.row + 1)
    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let path = getDirectory().appendingPathComponent("\(indexPath.row + 1).m4a")

    do {
    aduioPlayer = try AVAudioPlayer(contentsOf: path)
        aduioPlayer.play()


    }
    catch {

    }
}
@IBOutlet var buttonL:UIButton!

@IBAction func record() {

    if audioRecorder == nil{
        numberOfRecords += 1
        let fileName = getDirectory().appendingPathComponent("\(numberOfRecords).m4a")

        let settings = [AVFormatIDKey: Int(kAudioFormatMPEG4AAC), AVSampleRateKey : 12000, AVNumberOfChannelsKey: 1, AVEncoderAudioQualityKey : AVAudioQuality.high.rawValue]


        do {
            audioRecorder = try AVAudioRecorder(url: fileName, settings: settings)

            audioRecorder.delegate = self
            audioRecorder.record()
            buttonL.setTitle("Stop", for: .normal)
        }
        catch {
            displayALert(title: "Ups", message: "Recording Failed")
        }


    }

    else {
        audioRecorder.stop()
        audioRecorder = nil
        buttonL.setTitle("Start", for: .normal)

        UserDefaults.standard.set(numberOfRecords, forKey: "myN")
    }

}

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    recordingSessioin = AVAudioSession.sharedInstance()

    AVAudioSession.sharedInstance().requestRecordPermission { (hasPermsionn) in
        if hasPermsionn{
            print("Yes")
        }
    }


    if let number:Int = UserDefaults.standard.object(forKey: "myN") as? Int
    {
        numberOfRecords = number
    }
}

func getDirectory() -> URL {
    let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
    let documentDirectory = paths[0]
    return documentDirectory

}

func displayALert(title : String, message: String){
    let alert = UIAlertController(title: title, message: "dismiss", preferredStyle:     .alert)
    alert.addAction(UIAlertAction(title: "diss", style: .default, handler: nil))

    present(alert, animated: true, completion: nil)
}
   }

You should try to follow the tutorial all the way and you will learn from it. He tells you how to refresh the data in the table view.

#3

I am not having a problem with the table view refreshing I am having trouble because I can not save the audio clips.

#4

But what I mean is, if you don’t refresh the table, how do you know it does (or doesn’t) record?

#5

Were you ever able to solve this issue?

#6

Had the same problem… Thanks

hi @samjonas,
if you can articulate the problem in detail, someone can help find a solution.

You must contact the author of that you tube video and ask them for details on how to solve your problem.

cheer,
