Create a function from code - swift

Question

How do I create a function from this code in swift3?
I have a button which is pressed then plays this sound "push"
How can it be simplified when there are lots of buttons? I don't want to add all codes to every button.
var myAudio = AVAudioPlayer()
// Add sound
do {
try myAudio = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath:
Bundle.main.path(forResource: "push", ofType: "mp3")!) as URL)
} catch {
NSLog("No file!")
}
//call the sound
myAudio.play()
I made this change
func play(name : String){
do {
try myAudio = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath:
Bundle.main.path(forResource: name, ofType: "mp3")!) as URL)
} catch {
NSLog("No file!")
}
}
#IBAction func buttonFirst(_ sender: UIButton) {
play(name: "push")
myAudio.play()
}
#IBAction func buttonSecond(_ sender: UIButton) {
play(name: "second")
myAudio.play()
}
I got this output:
2017-07-25 16:13:23.270349+0100 sound[1728:933024] [aqme] 254: AQDefaultDevice (173): skipping input stream 0 0 0x0
Is that a problem?

Answer 1

I think you forgot the prepare
var audioPlayer = AVAudioPlayer()
let sound = URL(fileURLWithPath: Bundle.main.path(forResource: "sound", ofType: "mp3")!)
try! AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try! AVAudioSession.sharedInstance().setActive(true)
try! audioPlayer = AVAudioPlayer(contentsOf: sound)
audioPlayer.prepareToPlay()
audioPlayer.play()

You can use it in the following way
var myAudio : AVAudioPlayer?
func playSound(){
let path = Bundle.main.path(forResource: "push", ofType:"mp3")!
let url = URL(fileURLWithPath: path)
do {
let sound = try AVAudioPlayer(contentsOf: url)
self.myAudio = sound
sound.numberOfLoops = 1
sound.prepareToPlay()
sound.play()
} catch {
print("error loading file")
// couldn't load file :(
}
}
Furthermore you can use SwiftySound that lets you play sounds easily in Swift 3.
for example
Sound.play(file: "push.mp3")
