I'm new in iOS. I have written this code, which plays only one audio file when tapping a UIButton. I would like to play multiple sound randomly. How to set it? Thank you!
import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer: AVAudioPlayer!
#IBAction func playButtonPressed(_ sender: UIButton) {
if let soundURL = Bundle.main.url(forResource: "kompilacja", withExtension: "mp3") {
do {
audioPlayer = try AVAudioPlayer(contentsOf: soundURL)
}
catch {
print(error)
}
audioPlayer.play()
}else{
print("Karwasz twarz! Brak pliku audio, Panie!")
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
}
Put all of your sound file names in an array and use the randomElement method to choose your sound.
#IBAction func playButtonPressed(_ sender: UIButton) {
let sounds = ["kompilacja", "another sound", "yet another sound"]
guard let sound = sounds.randomElement(),
let soundURL = Bundle.main.url(forResource: sound, withExtension: "mp3") else { return }
do {
audioPlayer = try AVAudioPlayer(contentsOf: soundURL)
}
catch {
print(error)
}
audioPlayer.play()
}

import UIKit
import AVFoundation
class AVAudioPlayer : NSObject {
}
class ViewController: UIViewController {
#IBAction func keyPressed(_ sender: UIButton) {
}
override func viewDidLoad() {
super.viewDidLoad()
}
}
func playSound() {
let player: AVAudioPlayer?
guard let sound = Bundle.main.url(forResource: "C", withExtension: "wav") else { return }
do {
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer(contentsOfURL: sound, fileTypeHint: AVFileType.wav.rawValue)
guard let player = player else { return }
func play() -> Bool {}
} catch let error {
print(error.localizedDescription)
}
Xcode gives me an error in this line player = try AVAudioPlayer(contentsOfURL: sound, fileTypeHint: AVFileType.wav.rawValue) saying that Argument passed to call that takes no arguments
Replace '(contentsOfURL: sound, fileTypeHint: AVFileType.wav.rawValue)' with '' and when I try to fix it, it gives me this error: Cannot assign value of type 'AVAudioPlayer.Type' to type 'AVAudioPlayer'. Can somebody help me? PS sorry for bold, Stack wouldn't let me post because it had "too much code in it".
After the help from Sweeper, my code looks like this:
import AVFoundation
class ViewController: UIViewController {
var player: AVAudioPlayer?
#IBAction func keyPressed(_ sender: UIButton) {
}
override func viewDidLoad() {
super.viewDidLoad()
}
}
func playSound() {
guard let sound = Bundle.main.url(forResource: "C", withExtension: "wav") else { return }
do {
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer
guard let player = player else { return }
func play() -> Bool {}
} catch let error {
print(error.localizedDescription)
}
As I was saying in the comments, now it gives me this error: Use of unresolved identifier 'player'
You need to provide init(contentsOf:) throws method to initialize the player. Here is the code you need:
class ViewController: UIViewController {
var player: AVAudioPlayer?
func playSound() {
guard let sound = Bundle.main.url(forResource: "C", withExtension: "wav") else { return }
do {
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer(contentsOf: sound)
player?.play()
} catch let error {
print(error.localizedDescription)
}
}
}
I am trying to play some sound files with buttons but pressing the button throws me this error Thread 1: EXC_BAD_ACCESS (code=1, address=0x58) on line
audioPlayer.play()
I have looked for possible solutions and I can't find anything related to that error, the function of my code runs well until the print, this is my complete code.
import UIKit
import AVFoundation
class ViewController: UIViewController {
var track: String? = nil
var audioPlayer = AVAudioPlayer()
#IBAction func heavyButton(_ sender: Any) {
track = "H"
print("heavy machine gun \(track!)")
reproducirAudio(audio: track!)
audioPlayer.play()
}
func reproducirAudio(audio: String) {
do {
print("entro a la funcion de reproducir")
audioPlayer = try AVAudioPlayer(contentsOf: URL.init(fileURLWithPath: Bundle.main.path(forResource: audio, ofType: "mp3")!))
audioPlayer.prepareToPlay()
} catch {
print(error)
}
}
}
i found a solution, this is for iOS13
import UIKit
import AVFoundation
class ViewController: UIViewController {
var track: String? = nil
var audioPlayer: AVAudioPlayer?
#IBAction func heavyButton(_ sender: Any) {
track = "H"
print("heavy machine gun \(track!)")
reproducirAudio(audio: track!)
}
func reproducirAudio(audio: String) {
let path = Bundle.main.path(forResource: "\(audio).mp3", ofType:nil)!
let url = URL(fileURLWithPath: path)
do {
audioPlayer = try AVAudioPlayer(contentsOf: url)
audioPlayer?.play()
} catch {
// couldn't load file :(
}
}
I have a simple program which has one button and its only function is to trigger an sound output.
The app works perfectly when tested on an iOS simulator, but when I test it on an iPhone, the app is not playing any sound. I have tested this on two iPhones.
This was working once upon a time. I don't know if updating to iOS 10 has caused the issue.
Here is my code:
//Code
import UIKit
import AVFoundation
var audioPlayer = AVAudioPlayer()
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let music = Bundle.main.path(forResource: "sound", ofType: "wav")
do {
audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: music! ))
}
catch{
print(error)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func playSound(_ sender: UIButton) {
audioPlayer.play()
}
}
Would be grateful for any answers.
Thanks.
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let music = Bundle.main.path(forResource: "sound", ofType: "wav")
do {
audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: music! ))
audioPlayer.delegate = self
audioPlayer.preparedToPlay()
}
catch{
print(error)
}
}
import UIKit
import AVFoundation
class ViewController: UIViewController {
var btnSound: AVAudioPlayer!
override func viewDidLoad() {
super.viewDidLoad()
//locate resource
let path = Bundle.main.path(forResource: "sound", ofType: "wav")
let music = URL(fileURLWithPath: path!)
do{
try btnSound = AVAudioPlayer(contentsOf: music)
btnSound.prepareToPlay()
} catch let err as NSError{
print(err.debugDescription)
}
}
}
func playSound(){
if btnSound.isPlaying{
//stop playing sound file if already playing
btnSound.stop()
}
//play sound
btnSound.play()
}
#IBAction func playSound(sender: UIButton){
//call playSound function on pressing the button you attach this function to
playSound()
}
I have three buttons and I'm trying to get a sound to play with each button.
The sounds don't play on the simulator wondering what was going wrong in my code.
import UIKit
import AVFoundation
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func mmm_sound(sender: UIButton) {
playSound("mmm")
}
#IBAction func aww_sound(sender: UIButton) {
playSound("aww")
}
#IBAction func maniacal_sound(sender: UIButton) {
playSound("hah")
}
//sound function
func playSound(soundName: String)
{
let sound = NSURL(fileURLWithPath:NSBundle.mainBundle().pathForResource(soundName, ofType: "wav")!)
do{
let audioPlayer = try AVAudioPlayer(contentsOfURL:sound)
audioPlayer.prepareToPlay()
audioPlayer.play()
}catch {
print("Error getting the audio file")
}
}
}
You should make AVAudioPlayer as global variable as local variable of 'AVAudioPlayer' get deallocate before it plays, your code can like this
//at top
var audioPlayer = AVAudioPlayer()
func playSound(soundName: String)
{
let sound = NSURL(fileURLWithPath:NSBundle.mainBundle().pathForResource(soundName, ofType:"wav")!)
do{
audioPlayer = try AVAudioPlayer(contentsOfURL:sound)
audioPlayer.prepareToPlay()
audioPlayer.play()
}catch {
print("Error getting the audio file")
}
}
I'm trying to play a sound with AVAudioPlayer but it won't work.
Edit 1: Still doesn't work.
Edit 2: This code works. My device was in silent mode.
import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("button-09", ofType: "wav"))
println(alertSound)
var error:NSError?
audioPlayer = AVAudioPlayer(contentsOfURL: alertSound, error: &error)
audioPlayer.prepareToPlay()
audioPlayer.play()
}
}
Made modification to your code:
import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("button-09", ofType: "wav"))
println(alertSound)
// Removed deprecated use of AVAudioSessionDelegate protocol
AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
AVAudioSession.sharedInstance().setActive(true, error: nil)
var error:NSError?
audioPlayer = AVAudioPlayer(contentsOfURL: alertSound, error: &error)
audioPlayer.prepareToPlay()
audioPlayer.play()
}
}
Swift 3 and Swift 4.1:
import UIKit
import AVFoundation
class ViewController: UIViewController {
private var audioPlayer: AVAudioPlayer?
override func viewDidLoad() {
super.viewDidLoad()
let alertSound = URL(fileURLWithPath: Bundle.main.path(forResource: "button-09", ofType: "wav")!)
print(alertSound)
try! AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try! AVAudioSession.sharedInstance().setActive(true)
try! audioPlayer = AVAudioPlayer(contentsOf: alertSound)
audioPlayer!.prepareToPlay()
audioPlayer!.play()
}
}
As per Swift 2 the code should be
var audioPlayer : AVAudioPlayer!
func playSound(soundName: String)
{
let coinSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(soundName, ofType: "m4a")!)
do{
audioPlayer = try AVAudioPlayer(contentsOfURL:coinSound)
audioPlayer.prepareToPlay()//there is also an async version
audioPlayer.play()
}catch {
print("Error getting the audio file")
}
}
Your audio play will be deallocated right after viewDidLoad finishes since you assign it to a local variable. You need to create a property for it to keep it around.
The solution is for AudioPlayer which has play/pause/stop button in the navigation bar as bar button items
In Swift 2.1 you can use the below code
import UIKit
import AVFoundation
class ViewController: UIViewController {
var player:AVAudioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
let audioPath = NSBundle.mainBundle().pathForResource("ARRehman", ofType: "mp3")
var error:NSError? = nil
do {
player = try AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: audioPath!))
}
catch {
print("Something bad happened. Try catching specific errors to narrow things down")
}
}
#IBAction func play(sender: UIBarButtonItem) {
player.play()
}
#IBAction func stop(sender: UIBarButtonItem) {
player.stop()
print(player.currentTime)
player.currentTime = 0
}
#IBAction func pause(sender: UIBarButtonItem) {
player.pause()
}
#IBOutlet weak var sliderval: UISlider!
#IBAction func slidermov(sender: UISlider) {
player.volume = sliderval.value
print(player.volume)
}
}
This will work.....
import UIKit
import AVFoundation
class ViewController: UIViewController {
var ding:AVAudioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
prepareAudios()
ding.play()
}
func prepareAudios() {
var path = NSBundle.mainBundle().pathForResource("ding", ofType: "mp3")
ding = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: path!), error: nil)
ding.prepareToPlay()
}
}
Use This Function to make sound in Swift (You can use this function where you want to make sound.)
First Add SpriteKit and AVFoundation Framework.
import SpriteKit
import AVFoundation
func playEffectSound(filename: String){
runAction(SKAction.playSoundFileNamed("\(filename)", waitForCompletion: false))
}// use this function to play sound
playEffectSound("Sound File Name With Extension")
// Example :- playEffectSound("BS_SpiderWeb_CollectEgg_SFX.mp3")
This is a pretty old question, but I did not see an answer that worked with Swift 3.0 so I modernized the code and added some safety checks to prevent crashes.
I also took the approach of pulling the playing part out into its own function to help with re-use for anyone coming across this answer.
import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer: AVAudioPlayer?
override func viewDidLoad() {
super.viewDidLoad()
play(for: "button-09", type: "wav")
}
func play(for resource: String, type: String) {
// Prevent a crash in the event that the resource or type is invalid
guard let path = Bundle.main.path(forResource: resource, ofType: type) else { return }
// Convert path to URL for audio player
let sound = URL(fileURLWithPath: path)
do {
audioPlayer = try AVAudioPlayer(contentsOf: sound)
audioPlayer?.prepareToPlay()
audioPlayer?.play()
} catch {
// Create an assertion crash in the event that the app fails to play the sound
assert(false, error.localizedDescription)
}
}
}
Swift 4.2 onwards, AudioSession category setup options have been changed. (Try following code for Swift 4.2 onwards)
import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer: AVAudioPlayer?
override func viewDidLoad() {
super.viewDidLoad()
prepareAudioSession()
}
func prepareAudioSession() -> Void {
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, mode: AVAudioSession.Mode.default, options: AVAudioSession.CategoryOptions.defaultToSpeaker)
try AVAudioSession.sharedInstance().setActive(true)
prepareAudioPlayer()
} catch {
print("Issue with Audio Session")
}
}
func prepareAudioPlayer() -> Void {
let audioFileName = "test"
let audioFileExtension = "mp3"
guard let filePath = Bundle.main.path(forResource: audioFileName, ofType: audioFileExtension) else {
print("Audio file not found at specified path")
return
}
let alertSound = URL(fileURLWithPath: filePath)
try? audioPlayer = AVAudioPlayer(contentsOf: alertSound)
audioPlayer?.prepareToPlay()
}
func playAudioPlayer() -> Void {
audioPlayer?.play()
}
func pauseAudioPlayer() -> Void {
if audioPlayer?.isPlaying ?? false {
audioPlayer?.pause()
}
}
func stopAudioPlayer() -> Void {
if audioPlayer?.isPlaying ?? false {
audioPlayer?.stop()
}
}
func resetAudioPlayer() -> Void {
stopAudioPlayer()
audioPlayer?.currentTime = 0
playAudioPlayer()
}
}
