Playing different sounds in TableView

Question

Now I want to play different sounds when I click buttons inside these table view cells. I am very new at programming and I couldn't figure out how to do this. I have created an array for my sound files but I don't know how to assign them to those buttons in a row. Thank you very much for your help

AND THIS IS MY CODE

import UIKit
import AVFoundation

class ViewController6: UIViewController, UITableViewDataSource, UITableViewDelegate {

    var audioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


//Array of Rifles

    var arrayOfRifles = ["AK47", "AUGA1", "FAMAS", "G36K", "K1A", "K2", "M4A1", "M4Silencer", "M16", "M60", "MicroGALIL", "QBZ95", "RPK", "ScarHeavy", "Scarlight", "SG552", "TAR21", "Tommy", "Type89", "XM8"]
    var buttonDataRifles = ["AK47", "AUGA1", "FAMAS", "G36K", "K1A", "K2", "M4A1", "M4Silencer", "M16", "M60", "MicroGALIL", "QBZ95", "RPK", "ScarHeavy", "Scarlight", "SG552", "TAR21", "Tommy", "Type89", "XM8"]

    var soundsArray: [NSURL] = [
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "AK47", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "AUGA1", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "FAMAS", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "G36K", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "K1A", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "K2", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "M4A1", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "M4Silencer", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "M16", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "M60", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "MicroGALIL", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "QBZ95", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "RPK", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "ScarHeavy", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "ScarLight", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "SG552", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "TAR21", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "Tommy", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "Type89", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "XM8", ofType: "mp3")!)
    ]




//Functions for tableView

    //Cell - For Rifles

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return (arrayOfRifles.count)
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell6 = tableView.dequeueReusableCell(withIdentifier: "cell6", for: indexPath) as! ViewControllerTableViewCell6

        cell6.myImage.image = UIImage(named: arrayOfRifles[indexPath.row] + ".jpg")
        cell6.myButton.setTitle(buttonDataRifles[indexPath.row], for: UIControlState.normal)
        return (cell6)

        cell6.myButton.tag = indexPath.row
        cell6.myButton.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)}

    @IBAction func buttonAction(_ sender: UIButton) {

        print("Button tapped")
        let tapedIndex = sender as UIButton
        let getUrl = soundsArray[tapedIndex] as! NSURL


    }


}

First of all you need to add action to button and assign some tag to that button to identify which one is clicked.do some code on cellForRowAt

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

cell6.myButton.tag = indexPath.row
cell6.myButton.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside)}

func buttonAction(sender: UIButton!) 
{ 
print("Button tapped")
let tapedIndex = sender as! UIButton
let getUrl = buttonDataRifles[tapedIndex.tag] as! NSURL 
}

What exactly do you mean by 'assign some tag to that button to identify which one is clicked'? – Volkan Elçi Nov 14 '16 at 10:35
We have to assign here cell6.myButton.tag = indexPath.row as tag so whenever we click on only row of button, so we can identify which button click on basis we can play song of that row. – Bucket Nov 14 '16 at 10:40
let getUrl = soundsArray[tapedIndex] as! NSURL I got an error in this line that says 'Cannot subscript a value of type 'NSURL' with an index of type 'UIButton' – Volkan Elçi Nov 14 '16 at 11:41
Can you share your code me ? so i can get more idea. – Bucket Nov 14 '16 at 11:43
I have just made one change "let getUrl = buttonDataRifles[tapedIndex.tag] as! NSURL" – Bucket Nov 14 '16 at 11:46
I have updated my first message and added my code. Thanks – Volkan Elçi Nov 14 '16 at 11:46
Yes but now when i 'return (cell6)' i get an error that says Expected declaration' – Volkan Elçi Nov 14 '16 at 11:55
i think you have return cell by end of method – Bucket Nov 14 '16 at 11:57
do like return cell6 instead of return (cell6) – Bucket Nov 14 '16 at 12:02
Nothing changed. Still same error. Man!! This is annoying – Volkan Elçi Nov 14 '16 at 12:05
you are missing cell6! – Bucket Nov 14 '16 at 12:09
What do you mean? – Volkan Elçi Nov 14 '16 at 12:12
trying to return like "return cell6! " or return cell6 as! UITableViewCell " – Bucket Nov 14 '16 at 12:19
Fixed it!! .touchUpInside)} there is a curly bracket here and we didnt see it :) Now what should i do next? I am not sure – Volkan Elçi Nov 14 '16 at 12:41
well sorry for being a pain in the ass but i didn't understand what you mean – Volkan Elçi Nov 14 '16 at 12:47
explain here what do want to do next ? – Bucket Nov 14 '16 at 12:50
I want my buttons in my cells to play my audio files. For example first button in the first cell plays first audio file in my soundsArray, second button in the second cell plays second audio file in my soundsArray etc – Volkan Elçi Nov 14 '16 at 12:52
if you dont know how play audio then please refer this answer http://stackoverflow.com/questions/24393495/playing-a-sound-with-avaudioplayer if you still not clear let me know – Bucket Nov 14 '16 at 12:57

If u'r sounds not more that 30 sec I suggest to use AudioToolbox. This framework has specially designed functionality for such purpose.

Objective-C

import framework
```
#import <AudioToolbox/AudioToolbox.h>
```
make reference for your sound with creating SystemSoundID like
```
@property (assign, nonatomic) SystemSoundID soundIDOne;
```

Prepare you'r sonds in the very begginning

AudioServicesCreateSystemSoundID ( (__bridge CFURLRef)([[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Swish" ofType:@"wav"]]), &_soundIDDone);

Play sound

AudioServicesPlaySystemSound(_soundIDOne);

If u need completion - add handler

AudioServicesAddSystemSoundCompletion(_soundIDOne, NULL, NULL, playSoundFinished, NULL);


void playSoundFinished (SystemSoundID sound, void *data) {
    //do stuff here
}

Swift 2.2

    import AudioToolbox

    private var soundID:SystemSoundID?

    if let filePath = NSBundle.mainBundle().pathForResource("name", ofType: "type") {
        let pathToResource = NSURL(fileURLWithPath: filePath)
        soundID = 0
        if var soundID = soundID {
            AudioServicesCreateSystemSoundID(pathToResource, &soundID)
        }
    }

    if var soundID = soundID {
        AudioServicesPlaySystemSound(soundID)
    }

    //or create extension

    extension SystemSoundID {
        static func playSound(soundName: String, fileExtension: String) {
            var soundID: SystemSoundID = 0
            if let filePath =  NSBundle.mainBundle().pathForResource(soundName, ofType: fileExtension) {
                let pathToResource = NSURL(fileURLWithPath: filePath)
                AudioServicesCreateSystemSoundID(pathToResource, &soundID)
                AudioServicesPlaySystemSound(soundID)
            }
        }
    }

    //and usage

    SystemSoundID.playSound("soundFileName", fileExtension: "extension")

For more look here

In case u want to use AVFoundation instead code will be like:

    import AVFoundation

    var audioPlayer = AVAudioPlayer() //create player

    //create all path to y'r resources

    var path:[NSURL] = []

    if let filePath =  NSBundle.mainBundle().pathForResource("soundName", ofType: "fileExtension") {
        let pathToResource = NSURL(fileURLWithPath: filePath)
        path.append(pathToResource)
    }

    //in the very start
    do {
        if let selectedPath = path.first {
            audioPlayer = try AVAudioPlayer(contentsOfURL: selectedPath)
            audioPlayer.prepareToPlay()
        }
    } catch {
        print(error)
    }

    audioPlayer.play()

In this case, u can get some delay before sound playing because of required prepareToPlay for AVAudioPlayer, to be sure that u can play sound u need a little bit more complex setup of AVPlayer with observation for status of player, if u like u can refer to this link. Also, if u have files with short duration this delay can be very small or even absent, anyway, as for me this is not preferred way to play a lot of sound files due to reason described above

And of cause I cant tell u about AVFoundationQueuePlayer, this is also good solution. Here is Apple Sample link
