You can use the method - (void)playInputClick, found in the UIDevice class. You can access an instance of this class using the static method + (UIDevice *)currentDevice. Use this method to attatch the default input sound to your own custom UI.

 - (IBAction)startPlayback:(UIButton *)sender {
       
           NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
           resourcePath = [resourcePath stringByAppendingString:@"/grabbag.m4a"];
           NSLog(@"Path to play: %@", resourcePath);
           NSError* err;

         
           player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:resourcePath] error:&err];

           if( err ){
               //bail!
               NSLog(@"Failed with reason: %@", [err localizedDescription]);
           }
           else{
               player.delegate = self;
               [player play];
           }
       
     }
