How can I stop this music playing from another class file?
eg:

The music starts playing in the menu.h/.m

menu.h
---------

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


@interface Menu : UIViewController {
	
	AVAudioPlayer* backgroundMusic;

}

@end

menu.m
---------

- (void)viewDidLoad {
	NSString *pathToMusicFile = [[NSBundle mainBundle] pathForResource:@"background" ofType:@"mp3"];
	
	backgroundMusic = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:pathToMusicFile] error:NULL];
	
	backgroundMusic.numberOfLoops = -1;
	backgroundMusic.volume = 0.2;
	[backgroundMusic play];
    [super viewDidLoad];
}

Now that the song is playing, how can I stop it from this class?

options.h
-----------

@interface Options : UIViewController {
	
	IBOutlet UISwitch *musicSwitch;
	IBOutlet UISwitch *soundSwitch;

}

@property (nonatomic, retain) UISwitch *musicSwitch;
@property (nonatomic, retain) UISwitch *soundSwitch;

options.m
-----------

@synthesize musicSwitch;
@synthesize soundSwitch;

-(IBAction)musicSwitchChange:(id)sender
{
	if(musicSwitch.on)
	{
		
	}
	else
	{
		
	}
}
-(IBAction)soundSwitchChange:(id)sender
{
	if(soundSwitch.on)
	{
		
	}
	else
	{
		
	}
}

Thanks

Don't do that.

If you have background music, create a MusicController class to control it. Then send messages to the instance of that class from whatever object you're in. So instantiate the object in your appDelegate's appDidLoad, then send a message from your menu class object to start the music. Then you can send a message from your options class object to stop it.

Ok I see the structure but how do I do the actual code?

What part don't you understand? I'm not going to write it for you....

I'm not expecting you to :P If the instance is created in one class, how can I control it from another?

By getting a reference (pointer) to that object. In this case, the musicPlayer object would normally be an instance variable of the AppDelegate class. So you use a property of the AppDelegate to get that reference and send the message directly. There's about a dozen threads a day in this forum about how to message one class object from another.

I can't find any code examples, can you point me in the right direction? Thanks
