I'm having some trouble playing a sound which is attached to a button/IBAction.
When I do the exact same thing for iOS in Xcode, it works perfectly. However, when I do this for OS X, it doesn't work. Any ideas?
import Cocoa
import AVFoundation
class ViewController: NSViewController, NSSpeechRecognizerDelegate {
var pingAudioPlayer : AVAudioPlayer?
var sr = NSSpeechRecognizer()
#IBOutlet var output: NSTextView?
func playPing(){
let pingSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("ping", ofType: "mp3")!)
pingAudioPlayer = AVAudioPlayer(contentsOfURL: pingSound, error: nil)
pingAudioPlayer!.prepareToPlay()
pingAudioPlayer!.currentTime = 0
pingAudioPlayer!.play()
}
#IBAction func soundTest(sender: AnyObject) {
playPing()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
sr.delegate = self
sr.commands = ["Ping", "Ping Mac"]
sr.startListening()
}
func speechRecognizer(sender: NSSpeechRecognizer, didRecognizeCommand command: AnyObject?) {
output!.string! += "\(command)\n"
playPing()
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
}
The main problem was the speechRecognizer method, it wasn't the right signature.
import AVFoundation
class ViewController: NSViewController, NSSpeechRecognizerDelegate {
var pingAudioPlayer : AVAudioPlayer?
var sr = NSSpeechRecognizer()
#IBOutlet var output: NSTextView?
func playPing(){
let pingSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("ping", ofType: "mp3")!)
pingAudioPlayer = try? AVAudioPlayer(contentsOfURL: pingSound)
pingAudioPlayer?.prepareToPlay()
pingAudioPlayer?.currentTime = 0
pingAudioPlayer?.play()
}
#IBAction func soundTest(sender: AnyObject) {
playPing()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
sr?.delegate = self
sr?.commands = ["Ping", "Ping Mac"]
sr?.startListening()
}
func speechRecognizer(sender: NSSpeechRecognizer, didRecognizeCommand command: String) {
output?.string! += "\(command)\n"
playPing()
}
}

I'm trying to make a simple music player. I want the label to display the current position of the AVMIDIPlayer. With my code the label is only updated once at the very beginning:
import UIKit
import AVFoundation
class ViewController: UIViewController {
var player:AVMIDIPlayer = AVMIDIPlayer()
var playerTime:Double = 999 {
didSet {
label.text = String(playerTime)
}
}
#IBOutlet var label: UILabel!
#IBAction func Play(_ sender: Any) {
player.play()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
do {
let audioPath = Bundle.main.path(forResource: “song”, ofType: "mid")
try player = AVMIDIPlayer(contentsOf: NSURL(fileURLWithPath: audioPath!) as URL, soundBankURL: nil)
playerTime = player.currentPosition
}
catch {
}
}
}
What have I missed, please? Thank you. Scarlett
The reason the label isn’t updating is you’re setting the text in viewDidLoad which is called only once. Use a Timer to update the label.
import UIKit
import AVFoundation
class ViewController: UIViewController {
var player:AVMIDIPlayer = AVMIDIPlayer()
var playerTime:Double = 999 {
didSet {
label.text = String(playerTime)
}
}
var timer = Timer()
#IBOutlet var label: UILabel!
#IBAction func Play(_ sender: Any) {
player.play()
// this will execute every 0.1 seconds, allowing you to update the label.
timer = Timer.scheduledTimer(withTimeInterval: 0.1, repeats: true) { _ in
self.playerTime += 0.1
let min = self.playerTime.truncatingRemainder(dividingBy: 3600)) / 60
let sec = self.playerTime.truncatingRemainder(dividingBy: 60)
self.label.text = String(format: "%02d:%02d", min, sec)
}
}
func stop() {
// when you stop playback
timer.invalidate()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
do {
let audioPath = Bundle.main.path(forResource: “song”, ofType: "mid")
try player = AVMIDIPlayer(contentsOf: NSURL(fileURLWithPath: audioPath!) as URL, soundBankURL: nil)
playerTime = player.currentPosition
}
catch {
}
}
}
I am trying to stream a music from remote url. I am trying to run this in iOS 11 but it not play the music.
ViewController
var session = AVAudioSession.sharedInstance()
var LQPlayer: AVPlayer?
let LOW_URL = URL(string: "http://someLInk.pls")! // not an original url provided at this time.
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.avPlayerSetup()
}
func avPlayerSetup() {
do {
try session.setCategory(AVAudioSessionCategoryPlayback)
try session.overrideOutputAudioPort(.none)
try session.setActive(true)
} catch {
print("AVPlayer setup error \(error.localizedDescription)")
}
}
func initPlayer() {
LQPlayer = AVPlayer(url: LOW_URL)
print("player allocated")
}
func deAllocPlayer() {
LQPlayer = nil
print("player deallocated")
}
#IBAction func playBtn(_ sender: Any) {
initPlayer()
LQPlayer?.play()
}
#IBAction func pauseBtn(_ sender: Any) {
LQPlayer?.pause()
deAllocPlayer()
}
}
I set Allow Arbitrary Loads YES in info.plist.
Above code the URL I given is dummy. Actual url is working fine.
Working Code with Live Video Stream
#IBOutlet weak var player_View: UIView!
var LQPlayer: AVPlayer?
let LOW_URL = URL(string:"http://www.streambox.fr/playlists/test_001/stream.m3u8")!
override func viewDidLoad() {
super.viewDidLoad()
self.avPlayerSetup()
LQPlayer = AVPlayer.init(url: LOW_URL)
let avPlayerView = AVPlayerViewController()
avPlayerView.view.frame = self.player_View.bounds
avPlayerView.player = LQPlayer
self.player_View.addSubview(avPlayerView.view)
}
func avPlayerSetup() {
do {
try audioSession.setCategory(AVAudioSessionCategoryPlayback)
try audioSession.overrideOutputAudioPort(AVAudioSessionPortOverride.speaker)
try audioSession.setActive(true)
} catch {
print("AVPlayer setup error \(error.localizedDescription)")
}
}
func initPlayer() {
LQPlayer = AVPlayer(url:LOW_URL)
print("player allocated")
}

I'm very beginner of programming and start studying Swift to make a piano app for fun.
I have a trouble to play a sound when press a button.
I've searched some website but I'm too beginner to understand...
http://www.tmroyal.com/playing-sounds-in-swift-avaudioplayer.html
http://www.rockhoppertech.com/blog/swift-avfoundation/
Could you please tell me how can I play my "C.m4a" sound when press a "PainoC" button?
Here is my "view controller.swift".
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func PianoC(sender: AnyObject) {
}
}
I hope it will help you.
import UIKit
import AVFoundation
class ViewController: UIViewController {
// make sure to add this sound to your project
var pianoSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("C", ofType: "m4a"))
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
audioPlayer = AVAudioPlayer(contentsOfURL: pianoSound, error: nil)
audioPlayer.prepareToPlay()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func PianoC(sender: AnyObject) {
audioPlayer.play()
}
}
Latest Swift 4.2 :
let pianoSound = URL(fileURLWithPath: Bundle.main.path(forResource: "btn_click_sound", ofType: "mp3")!)
var audioPlayer = AVAudioPlayer()
#IBAction func PianoC(sender: AnyObject) {
do {
audioPlayer = try AVAudioPlayer(contentsOf: pianoSound)
audioPlayer.play()
} catch {
// couldn't load file :(
}
}
Swift 3
the syntax is now as follows:
first add import AVFoundation on top of the code to have access to AVFoundation Framework.
import UIKit
import AVFoundation
class ViewController: UIViewController {
//this is your audio playback instance
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
// address of the music file.
let music = Bundle.main.path(forResource: "Music", ofType: "mp3")
// copy this syntax, it tells the compiler what to do when action is received
do {
audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: music! ))
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient)
try AVAudioSession.sharedInstance().setActive(true)
}
catch{
print(error)
}
}
//this runs the do try statement
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func play(_ sender: AnyObject) {
audioPlayer.play()
}
#IBAction func stop(_ sender: AnyObject) {
audioPlayer.stop()
}
}
SWIFT 5
import AVFoundation
class Test {
var player: AVAudioPlayer!
func playAudio() {
let url = Bundle.main.url(forResource: "Sound", withExtension: "mp3")
player = try! AVAudioPlayer(contentsOf: url!)
player.play()
}
}
In Swift 4:
import AVFoundation
class ViewController: UIViewController, ARSCNViewDelegate, ARSessionDelegate {
let popSound = Bundle.main.url(forResource: "Pop", withExtension: "mp3")
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
do {
audioPlayer = try AVAudioPlayer(contentsOf: popSound!)
audioPlayer.play()
} catch {
print("couldn't load sound file")
}
}
import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func button1Action(sender: AnyObject) {
let CatSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("Meow-sounds", ofType: "mp3")!)
do {
audioPlayer = try AVAudioPlayer(contentsOfURL: CatSound)
audioPlayer.prepareToPlay()
} catch {
print("Problem in getting File")
}
audioPlayer.play()
}
}

This worked for me try it out.
import UIKit
import AVFoundation
class ViewController: UIViewController, AVAudioPlayerDelegate{
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func notePressed(_ sender: UIButton) {
let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: "note1", ofType: "wav")!)
do{
audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
}catch {
print("there was some error. The error was \(error)")
}
audioPlayer.play()
}
}
In Swift 3:
import UIKit
import AVFoundation
class QuestionView: UIViewController {
var btnButton = UIButton()
var player = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
btnButton.frame = CGRect(x: 100, y: 100, width: 100, height: 100)
btnButton.backgroundColor = UIColor.blue
btnButton.addTarget(self, action: #selector(ButtonSound), for: .touchUpInside)
}
func ButtonSound() {
do {
// make sure to add this sound to your project
let audioPath = Bundle.main.path(forResource: "Click", ofType: "mp3")
try player = AVAudioPlayer(contentsOf: URL(fileURLWithPath: audioPath!) as URL)
} catch {
print("Error !")
}
player.play()
}
}
If you just want a click effect, the code below will work.
The bird file must be in xcode.
self.run(SKAction.playSoundFileNamed("Bird.mp3", waitForCompletion:false))
I'm trying to trigger a sound after I say a word. The speech recognizer recognizes the word when I say it and I've set it up so it puts out a string each time I say the command. What I'd like to do is trigger a sound after I say that specific word. This is what I have so far.
import Cocoa
import AVFoundation
class ViewController: NSViewController, NSSpeechRecognizerDelegate {
var ping = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("ping", ofType: "mp3")!)
var pingAudioPlayer = AVAudioPlayer()
var sr = NSSpeechRecognizer()
#IBOutlet var output: NSTextView?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
pingAudioPlayer = AVAudioPlayer(contentsOfURL: ping, error: nil)
sr.delegate = self
sr.commands = ["Ping", "Ping Mac"]
sr.startListening()
}
func speechRecognizer(sender: NSSpeechRecognizer, didRecognizeCommand command: AnyObject?) {
output!.string! += "\(command)\n"
pingAudioPlayer.play()
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
UPDATE:
import Cocoa
import AVFoundation
class ViewController: NSViewController, NSSpeechRecognizerDelegate {
var ping = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("ping", ofType: "mp3")!)
let pingAudioPlayer = AVAudioPlayer()
var sr = NSSpeechRecognizer()
#IBOutlet var output: NSTextView?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
sr.delegate = self
sr.commands = ["Ping", "Ping Mac"]
sr.startListening()
}
func speechRecognizer(sender: NSSpeechRecognizer, didRecognizeCommand command: AnyObject?) {
output!.string! += "\(command)\n"
var pingAudioPlayer = AVAudioPlayer(contentsOfURL: ping, error: nil)
pingAudioPlayer.prepareToPlay()
pingAudioPlayer.play()
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
}
Not sure why the audio player is not playing the sound once the word is recognized. Any ideas?
You aren't telling the audio player which sound to play. Try this:
func speechRecognizer(sender: NSSpeechRecognizer, didRecognizeCommand command: AnyObject?) {
do{
let pingAudioPlayer = try AVAudioPlayer(contentsOfURL:ping)
pingAudioPlayer.prepareToPlay()
pingAudioPlayer.play()
}catch {
print("Error getting the audio file")
}
}
I installed FacebookSDK using Cocoapods, according to Terminal, I have installed FacebookSDK 4.8.0 (CoreKit, ShareKit and LoginKit), I imported the .h files in my BH-File.h, and already initialized everything in my AppDelegate.
For some reason, when trying to log in using a custom button, when I initialize FBLoginManager, I get an error Use of undeclared type "FBLoginManager".
this is my code
if (FBSDKAccessToken.currentAccessToken() == nil)
{
let fbLoginManager : FBSDKLoginManager =
fbLoginManager.logInWithReadPermissions(["public_profile", "email"], fromViewController: self, handler: { (loginResult, error) -> Void in
if error == nil {
print (FBSDKAccessToken.currentAccessToken().tokenString)
}
else {
print ("ERROR*****: \(error)")
}
})
}
What fixed to me was adding import FBSDKCoreKit and FBSDKLoginKit to my class, for some reason is not enough adding it in the BH-file.h
Try something like this, I just checked the code and it works (it's not exactly what you're looking for but I'm sure you can modify it as needed)
import UIKit
import FBSDKCoreKit
import FBSDKLoginKit
class ProfileViewController: UIViewController,FBSDKLoginButtonDelegate {

self,
selector: "fbProfileChanged:",
name: FBSDKProfileDidChangeNotification,
object: nil)
FBSDKProfile.enableUpdatesOnAccessTokenChange(true)
// If we have a current Facebook access token, force the profile change handler
if ((FBSDKAccessToken.currentAccessToken()) != nil)
{
self.fbProfileChanged(self)

}
else if (result.isCancelled)
{
// Logged out?
print( "Login Cancelled")
}
else
{
// Logged in?
print( "Logged in, segue now")
self.performSegueWithIdentifier("showHome", sender: self)
}
}
func loginButtonDidLogOut(loginButton: FBSDKLoginButton!) {

//see bitfountain

let url = NSURL(string: strProfilePicURL, relativeToURL: NSURL(string: "http://graph.facebook.com/"))
let imageData = NSData(contentsOfURL: url!)
let image = UIImage(data: imageData!)
self.nameLabel.text = fbProfile.name
self.imageView.image = image
self.nameLabel.hidden = false
self.imageView.hidden = false
