How to Play a Sound Effect with AudioServices - Objective C

I have been searching the web for a way to play sounds in Objective C and I have found plenty of answers. However, when I try to play something three "Apple Mach-O Linker Errors" pop up.

Here is my code:

viewController.m

-(IBAction)shoot{
    tempSound *sound = [[tempSound alloc]init];
    [sound playSound:@"test" :@"wav"]  
}

tempSound.h

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

@interface tempSound : NSObject{
    SystemSoundID audioEffect;
}

-(void)playSound: (NSString*) fName : (NSString*) ext;

@end

tempSound.m 

@implementation tempSound

-(void)playSound:(NSString *)fName :(NSString *)ext
{
    NSString *path  = [[NSBundle mainBundle] pathForResource : fName ofType :ext];

    if ([[NSFileManager defaultManager] fileExistsAtPath:path]) {

        NSURL *pathURL = [NSURL fileURLWithPath:path];
        AudioServicesCreateSystemSoundID((__bridge CFURLRef)pathURL, &audioEffect);
        AudioServicesPlaySystemSound(audioEffect);
    }

    else{
        NSLog(@"Error, file not found: %@",path);
    }


}

@end

Thanks in advance!

You have to link against the AudioToolbox framework. (If you're using Xcode, you can add that in the "link with binaries" tab on the "build phases" section; if you're using a command line toolchain, you should add the -framework AudioToolbox linker flag.)
