NSSound Class help

[MacProgramer]

ok i am currently teaching myself how to develop for Leopard
(Cocoa + Objective-C)

i need help with a program using the NSSound Class

here is the code


#import "AppController.h"

@implementation AppController
- (IBAction)playMusic:(id)sender

{
NSSound* sound = [[NSSound alloc] initWithContentsOfFile: @"/Users/HomePortal/Music/TI - Whatever You Like.mp3" byReference:YES];
[sound play];
}

- (IBAction)stopMusic:(id)sender
{

}

@end



how do i get the action stopMusic: to stop the music when i press the button linked to the action stopMusic:

, any help would be appreciated

Instead of declaring sound inside the playMusic: method, declare it as an instance variable in your .h. Something like:

@interface AppController {
NSSound *sound;
}
...
@end

By declaring it here, the variable is accessible in any method in the class.

So then your playMusic: method might look like this:

- (IBAction)playMusic:(id)sender
{
sound = [[NSSound alloc] initWithContentsOfFile: @"/Users/HomePortal/Music/TI - Whatever You Like.mp3" byReference:YES];
[sound play];
}

And stopMusic:

- (IBAction)stopMusic:(id)sender
{
[sound stop];
}
