iOS Build a Simple iPhone App (iOS7) Animating and Intercepting Events Adding Sound

I'm trying to create a simple app to test my skills but having trouble with the sounds?

I'm creating an app that will play an animation and a sound when you touch the screen, then after the animation has played, randomly select and play a different sound. Here's my code so far!


#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
@property (strong, nonatomic) IBOutlet UILabel *label;
@property (strong, nonatomic) IBOutlet UIImageView *backgroundImageView;


#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>
@interface ViewController ()


@implementation ViewController {
    AVAudioPlayer *introSoundFX;
    AVAudioPlayer *baconSFX;
    AVAudioPlayer *bananaSFX;

- (void)viewDidLoad {
    [super viewDidLoad];

    NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"intro" ofType:@"mp3"];
    NSURL *url = [NSURL fileURLWithPath:soundPath];
    introSoundFX = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];

    NSString *soundPathTwo = [[NSBundle mainBundle] pathForResource:@"Bacon" ofType:@"mp3"];
    NSURL *urlTwo = [NSURL fileURLWithPath:soundPathTwo];
    baconSFX = [[AVAudioPlayer alloc] initWithContentsOfURL:urlTwo error:nil];

    NSString *soundPathThree = [[NSBundle mainBundle] pathForResource:@"Banana" ofType:@"mp3"];
    NSURL *urlThree = [NSURL fileURLWithPath:soundPathThree];
    bananaSFX = [[AVAudioPlayer alloc] initWithContentsOfURL:urlThree error:nil];

    self.backgroundImageView.animationImages = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"1"],
                                                [UIImage imageNamed:@"2"],
