Launching another application on button press in Cocoa app [closed]

Question

I am attempting to build an app that allows a user to press a button that says "Play DVD" and it will then launch DVDPlayer.app. I know the best way of doing this is by using NSWorkspace and launchApplication but my problem is getting the button to recognize the command. How do I get the button to work?

Here is the code that I have so far:

dvd.m

#import "dvd.h"

@implementation dvd


- (BOOL)openDvd{
    [[NSWorkspace sharedWorkspace] launchApplication:@"/Applications/DVDPlayer.app"];
    return TRUE;
    }

@end

dvd.h

#import <Foundation/Foundation.h>
#import <AppKit/AppKit.h>
#import <cocoa/Cocoa.h>
#import <ApplicationServices/ApplicationServices.h>

@interface dvd : NSObject

- (BOOL)openDvd;

@end

Any help would be greatly appreciated. Thanks in advance.

I don't see any connection to the button in your code. Your method lacks an IBAction, so it isn't hook up directly. Did you connect it in Interface Builder?
