I need some help with specific copy and paste code to help me get this running. I want users to click on a NSButton and it will launch safari or their default web browser.

I added a NSButton on my form and then added the declaration and implementation for that but still isn't working. why is it not working? Thanks in Advance...

@protocol RegistrationWindowDelegate

-(void) registrationDidFinished;

@end

@interface RegistrationWindowController : NSWindowController<HttpRequestDelegate,ChimpKitDelegate,NSWindowDelegate> {


    IBOutlet NSButton *pushApp1; //Newly added NSButton for opening Web URL

    IBOutlet NSWindow *registerWindow;
    IBOutlet NSWindow *privacyWindow;
    IBOutlet NSTextField *firstNameField, *lastNameField, *emailField, *verfilyEmailField;
    IBOutlet NSPopUpButton *countryPopUpBtn;
    IBOutlet NSButton *updateCheckBox, *promotionCheckBox;
    IBOutlet NSMenuItem *registerMenuItem;
    IBOutlet NSProgressIndicator *progressIndicator;
    IBOutlet NSButton *registerSoftware,*registerLater;
    id<RegistrationWindowDelegate> delegate;

}
@property(nonatomic,assign) id<RegistrationWindowDelegate> delegate;
- (id)initForRegistrationServer:(int) registrationServer withDelegate:(id<RegistrationWindowDelegate>) delegate;
+ (BOOL) isRegistered;
- (void) setRegistered:(BOOL)state;
- (void) openWindow:(id) sender;
- (BOOL)isValidEmail:(NSString *)email;
-(void) registerWithNormal;
- (void) registerWithMailChimpForApps;
- (NSArray *)addCountries;
