How to add multiple AVAudioPlayer in same ViewController

In my app I'm displaying 5 UIView and by touching any view sound will play. So how can I add multiple AVAudioPlayer in same ViewController.

For single View I'm adding this code to implement AVAudioPlayer

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Sound" ofType:@"MP3"]];

NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
if (error)
{
    NSLog(@"Error in audioPlayer: %@", [error localizedDescription]);
} else {
    audioPlayer.delegate = self;

    //theAudio.numberOfLoops = -1;
    [audioPlayer prepareToPlay];
}

So should I just create 5 AVAudioPlayer instantances and add to every view or any other way to reuse this code for every view?

You can create Multiple AudioPlayer instance using same code like this

In .h file

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>

@interface MultipleChoiceViewController : UIViewController<AVAudioPlayerDelegate>
{
    AVAudioPlayer *dingAudioPlayer;
    AVAudioPlayer *buzzAudioPlayer;
}
-(IBAction) playDingAudio:(id) sender;
-(IBAction) playBuzzAudio:(id) sender;

And in your .m file 

- (void)viewDidLoad
{
    dingAudioPlayer = [self loadAudio:@"ding Audio" audioType:@"mp3"];
    buzzAudioPlayer = [self loadAudio:@"buzz Audio" audioType:@"mp3"];
   [buzzAudioPlayer play];
}

- (AVAudioPlayer *)loadAudio:(NSString *)filename audioType:(NSString *)audioType{
    NSURL * url = [[NSBundle mainBundle] URLForResource:filename withExtension:audioType];
    NSError * error;
    AVAudioPlayer * player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
    if (!player) {
        NSLog(@"Error loading %@: %@", url, error.localizedDescription);
    } else {
        player.delegate = self;
        [player prepareToPlay];
    }
    return player;
}


#pragma mark - AvAudio Player delegate methods

-(void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
    if (player != dingAudioPlayer && player != buzzAudioPlayer) {
        player = nil;
    }
    NSLog(@"finished");
}
-(void)audioPlayerDecodeErrorDidOccur:(AVAudioPlayer *)player error:(NSError *)error
{
    NSLog(@"AVAudioPlayer Error : %@",error);
}
-(void)audioPlayerBeginInterruption:(AVAudioPlayer *)player
{
}
-(void)audioPlayerEndInterruption:(AVAudioPlayer *)player
{
}

-(IBAction) playDingAudio:(id) sender{
   [dingAudioPlayer play];
}
-(IBAction) playBuzzAudio:(id) sender{
   [buzzAudioPlayer play];
}

Use only One AVAudioPlayer instance to play sounds. All you have to do is,Assign different sound to each view and assign same playing sound method to all views.

make 5 urls like 

NSURL *urlsound1 = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Sound" ofType:@"MP3"]];
NSURL *urlsound2 = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Sound" ofType:@"MP3"]];

Pass urls as parameters to play method

You can implement it with one AVAudioPlayer, you have to create one common method for all your 5 view, when your touch method is called according to view you can set the sound file of AVAudioPlayer.
