Detecting an NSSlider value change

How do I wire up an action programmatically to my NSSlider to detect when the value changes?

I'm looking for the Cocoa equivalent of a UISlider that would be done with the following code.

[myUISlider addTarget:self action:@selector(valueChanged:) forControlEvents:UIControlEventValueChanged];

[slider setTarget:self];
[slider setContinuous:YES];
[slider setAction:@selector(valueChanged:)];

-(void)valueChanged:(NSSlider *)sender{ 

}

You'd use the following code:

[slider setTarget:self];
[slider setAction:@selector(valueChanged:)];

That's it.

NSSlider uses an NSSliderCell, which is a custom subclass of NSActionCell; I'd look over that documentation for the target action mechanism in Cocoa.
