So basically I have two audio players while using the AVFoundation. I want the second one to be played right after the first one finishes.
myFilePathString = NSBundle.mainBundle().pathForResource("\(workout[currentExercise])", ofType: "mp3")
#IBAction func startWorkout(sender: AnyObject) {
if let myFilePathString = myFilePathString {
let myFilePathURL = NSURL(fileURLWithPath: myFilePathString)
do {
try audioPlayer = AVAudioPlayer(contentsOfURL: myFilePathURL)
audioPlayer.play()
}catch {
print("Error")
}
}
This above one is to be the first
let path = NSBundle.mainBundle().pathForResource("Rest", ofType: "mp3")
let url = NSURL(fileURLWithPath: path!)
do {
let sound = try AVAudioPlayer(contentsOfURL: url)
secondAudioPlayer = sound
sound.play()
} catch {
print("error")
}
...while this one is to be played after. At the moment they play at the same time. Got any ideas for me?
Thank you in advance.

I am a total swift beginner and am working on a tutorial project (magic 8 ball) and have been successful at doing the following:
- play a specific sound when the "Ask" button is pressed.
- play a specific sound when for each of the randomly picked images
However now the sound that should play whenever the button is pressed only plays once and from there on i only hear the sounds that are being displayed with each image. Is this because I am "stuck" in the "if - else" loop ? Or do I have to delay the sounds that are being played for each image in the array ?
Thanks so much for your help !
Here is my code:
import UIKit
import AVFoundation
class ViewController: UIViewController {
#IBOutlet weak var magicBall: UIImageView!
var magicBallDisplay = 1
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
magicBall.image = #imageLiteral(resourceName: "theanswerisyes")
}
#IBAction func askButtonPressed(_ sender: UIButton) {
let magicBallArray = [ #imageLiteral(resourceName: "askagainlater"),#imageLiteral(resourceName: "no"),#imageLiteral(resourceName: "theanswerisyes"),#imageLiteral(resourceName: "yes"),#imageLiteral(resourceName: "noidea")]
magicBall.image = magicBallArray.randomElement()
let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: "Ask", ofType: "wav")!)
do{
audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
}catch {
print("there was some error. The error was \(error)")
}
audioPlayer.play()
if (magicBall.image?.isEqual(UIImage(named: "yes")))! {
let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: "yes", ofType: "mp3")!)
do{
audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
} catch {
print("there was some error. The error was \(error)")
}
audioPlayer.play()
}
else if (magicBall.image?.isEqual(UIImage(named: "no")))! {
let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: "no", ofType: "mp3")!)
do{
audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
} catch {
print("there was some error. The error was \(error)")
}
audioPlayer.play()
}
else if (magicBall.image?.isEqual(UIImage(named: "theanswerisyes")))! {
let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: "theanswerisyes", ofType: "mp3")!)
do{
audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
} catch {
print("there was some error. The error was \(error)")
}
audioPlayer.play()
}
else if (magicBall.image?.isEqual(UIImage(named: "noidea")))! {
let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: "noidea", ofType: "mp3")!)
do{
audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
} catch {
print("there was some error. The error was \(error)")
}
audioPlayer.play()
}
else if (magicBall.image?.isEqual(UIImage(named: "askagainlater")))! {
let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: "askagainlater", ofType: "mp3")!)
do{
audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
} catch {
print("there was some error. The error was \(error)")
}
audioPlayer.play()
}
}
}
I make a new project and change your code to this:
import UIKit
import AVFoundation
class ViewController: UIViewController {
#IBOutlet weak var magicBall: UIImageView!
// you never used this
//var magicBallDisplay = 1
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
magicBall.image = #imageLiteral(resourceName: "theanswerisyes")
}
#IBAction func askButtonPressed(_ sender: UIButton) {
// because you have audio file and image with equal name i made array of string
let magicBallArray = [ "yes","no","theanswerisyes","noidea","askagainlater"]
// check if i get not null item
guard let choosedImageName = magicBallArray.randomElement() else {return}
print(choosedImageName)
// set image with random picked name
magicBall.image = UIImage(named: choosedImageName)
// play ask sound
playSound(fileName: "Ask", fileType: "wav")
// play picked image sound after 10 second from now()
// change number to your needed time
DispatchQueue.main.asyncAfter(deadline: .now() + 10.0, execute: {
self.playSound(fileName: choosedImageName, fileType: "mp3")
})
}
private func playSound(fileName: String, fileType: String)
{
// check if you find the audio file
guard let url = Bundle.main.path(forResource: fileName, ofType: fileType) else {
print("path not found")
return
}
// make NSURL from path
let soundURL = NSURL(fileURLWithPath: url)
do{
audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
} catch {
print("there was some error. The error was \(error)")
}
audioPlayer.play()
}
}
I explain code for you.
I didn't enable the button. you can improve this code when you came stronger in swift
your code is really messy.
at first, I advise you to make a function for playing sound like that:
func playSound(fileName: String, fileType: String) {
let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: fileName, ofType: fileType)!)
do{
audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
}catch {
print("there was some error. The error was \(error)")
}
audioPlayer.play()
}
you must have a callback for first play sound. after finishing the first sound you can check your if-else or you can try switch-case.
also, you can use delay for playing second sound
I have had success playing sounds by pressing a button, by using the following code. However, I'd like to press a button and have that sound play in a loop/infinitely. How is this acheived? I'd also like to acheive pause/play functionality as well. Thanks in advance.
#IBAction func keyPressed(_ sender: UIB`utton) {
playSound(soundName: sender.currentTitle!)
}
func playSound(soundName: String) { //
let url = Bundle.main.url(forResource: soundName, withExtension: "wav")
player = try! AVAudioPlayer(contentsOf: url!)
player.play()
} // End of Play Sound
By default AVAudioPlayer plays its audio from start to finish then stops, but we can control how many times to make it loop by setting its numberOfLoops property. For example, to make your audio play three times in total, you’d write this:
player.numberOfLoops = 3
if you want the infinite loop then use
player.numberOfLoops = -1
for e.g
func playSound(soundName: String) { //
let url = Bundle.main.url(forResource: soundName, withExtension: "wav")
player = try! AVAudioPlayer(contentsOf: url!)
player.numberOfLoops = -1 // set your count here
player.play()
} // End of Play Sound
var audioPlayer: AVAudioPlayer?
func startBackgroundMusic() {
if let bundle = Bundle.main.path(forResource: "Guru_Nanak_Sahib_Ji", ofType: "mp3") {
let backgroundMusic = NSURL(fileURLWithPath: bundle)
do {
audioPlayer = try AVAudioPlayer(contentsOf:backgroundMusic as URL)
guard let audioPlayer = audioPlayer else { return }
audioPlayer.numberOfLoops = -1 // for infinite times
audioPlayer.prepareToPlay()
audioPlayer.play()
} catch {
print(error)
}
}
}
You can retain the player. Then in the player's completion delegate callback, start playing again. Or stop the player at any time, since you've retained a reference to it.
I am trying to play a sound but my current code bases the volume off of the ringtone volume. How to I change this to media volume?
var player: AVAudioPlayer?
...
func playSound(name: String) {
let url = Bundle.main.url(forResource: name, withExtension: "mp3")!
do {
player = try AVAudioPlayer(contentsOf: url)
guard let player = player else { return }
player.prepareToPlay()
player.play()
} catch let error {
print(error.localizedDescription)
}
}
...
playSound(name: "baby")
Only set that before you put some url into the player.
try? AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
To play sound using media volume you should do like this:
func play(){
let path = Bundle.main.path(forResource: "Plop", ofType: "mp3")!
let url = URL(fileURLWithPath: path)
do {
let sound = try AVAudioPlayer(contentsOf: url)
bombSoundEffect = sound
sound.play()
} catch {
// couldn't load file :(
}
}
i try to make iOS app to play some funny sound put when i click play no sound are out from speaker here is the code :
#IBAction func slow(sender: UIButton) {
if let filePath = NSBundle.mainBundle().URLForResource("io", withExtension: "mp3") {
let _a = try! AVAudioPlayer(contentsOfURL: filePath)
// Play
_a.play()
}else
{
print("error")
}
}
there is no error but i can't hear any sound at all
for how that face this problem
#IBAction func slow(sender: UIButton) {
if let path = NSBundle.mainBundle().pathForResource("io", ofType:"mp3") {
let fileURL = NSURL(fileURLWithPath: path)
player = try! AVAudioPlayer(contentsOfURL: fileURL)
player.prepareToPlay()
player.play()
}
else
{
print("error")
}
}
}
I want to play two sound files in my Swift app. "C1_bip.aif" and "false.aif".
They're both in the same folder in the project.
But when I start the app, the C1_bip sound is played and the false sound not and it prints Error to the Console.
The sound files are the same file type and I can play them both in the project explorer in Xcode.
if let path = NSBundle.mainBundle().pathForResource("C1_bip", ofType: "aif") {
audioPlayer = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: path),
fileTypeHint: "aif", error: nil)
if let sound = audioPlayer {
sound.prepareToPlay()
sound.play()
}
}
else {
println("Error")
}
if let path = NSBundle.mainBundle().pathForResource("false", ofType: "aif") {
audioPlayer = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: path),
fileTypeHint: "aif", error: nil)
if let sound = audioPlayer {
sound.prepareToPlay()
sound.play()
}
}
else {
println("Error")
}
Here is what I did in my test project:
let musicPath = NSBundle.mainBundle().pathForResource("bgmusic", ofType: "mp3")
let url = NSURL(fileURLWithPath: musicPath!)
do{
audioPlayer = try AVAudioPlayer(contentsOfURL: url)
}catch _ {
audioPlayer = nil
}
audioPlayer.numberOfLoops = -1
audioPlayer.prepareToPlay()
audioPlayer.play()
And it did work well:)
