Trying to create a button in Xcode Objective-C

Question

I am just trying something completely new and simple in Xcode. I was looking a tutorial to create a button that plays music or a sound. All seemed to be okay until preview time. There seems to be an expected identifier issue at IBAction as well as it expected something after (void). But each time I do as the prompt says the prompts multiply. I've tried to do as all of them said but then it was no longer the same function. Any ideas?

#import "ViewController.h"
#import <UIKit/UIKit.h>
#import <AudioToolbox/AudioToolbox.h>

@interface StrackerViewController : ViewController

//@end

//@implementation StrackerViewController: ViewController

- (IBAction) epic; {

    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @ "epic", CFSTR ("mp3"),NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
                    }

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

Your IBAction is not a properly formed function. It needs to be in the form:

-(IBAction) epic:(id)sender {

Once you have done that you should probably delete and remake the link with your storyboard as that is likely to be broken too.
