Swift xcode 8 - Using multiple buttons and audio files - swift

Question

New to Swift and Xcode - Need help playing multiple audio files with more than one buttons. I have been able to get it to play a single file with one of the buttons but don't wish to write the entire program for each button!
import UIKit
import AVFoundation
class SecondViewController: UIViewController {
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
// address of the music file
let music = Bundle.main.path(forResource: "File1", ofType: "mp3")
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 Play(_ sender: AnyObject) {
audioPlayer.play()
}
#IBAction func stop(_ sender: AnyObject) {
audioPlayer.stop()
audioPlayer.currentTime = 0
}
#IBOutlet weak var myVolumeController: UISlider!
#IBAction func controlVolume(_ sender: AnyObject) {
audioPlayer.volume = myVolumeController.value
}
}

Class structure is best choose for you (swift 3) :
import Foundation
import UIKit
class BUTTON {
class func instanceFromNib() -> UIView {
return UINib(nibName: "nib file name", bundle: nil).instantiate(withOwner: nil, options: nil)[0] as! UIView
}
var SELF :UIView
var buttonText : String
let BTN = UIButton(type: UIButtonType.custom) as UIButton
// CONSTRUCT INIT
init ( UIView_ : UIView , buttonText_ : String ) {
print("Button instance constructor")
SELF = UIView_;
buttonText = buttonText_;
}
func CREATE_BUTTON () {
BTN.setTitle(buttonText, for: UIControlState.normal )
BTN.backgroundColor = UIColor.red
BTN.frame.origin.x = 10
BTN.frame.origin.y = 100
BTN.frame.size = CGSize(width: 155, height: 155 )
BTN.frame.origin = CGPoint(x: 10, y: 20)
BTN.setTitleColor( UIColor.black , for: UIControlState.normal )
SELF.addSubview(BTN)
//let image = UIImage(named: "name") as UIImage?
//BTN.setImage(image, forState: .Normal)
//BTN.addTarget(self, action: "btnTouched:", forControlEvents:.TouchUpInside)
}}
Use it like this :
let MyButton1 = BUTTON( UIView_ : self.view , buttonText_ : "Nidza")
self.view can be also custom view or any other view
In your example you can put new option in init like PLAYER .
Every button will come with own player (to looks like sound mixer).
