The property syntax is great until you need one more thing.

Think of a NSView and that view displays a value.

 @synthesize value;

Now you also want to setNeedsDisplay: when a new value is set. So one
can override the setter.

 - (void)setValue:(NSString*)theValue
 {
   ...
   [self setNeedsDisplay:YES];
 }

but - you would have to implement the setter yourself. No big deal -
but... it sucks.
Is there a way to forward the setting to the originally synthesized
setter? Super cannot be it.

Of course one could add another selector that to the interface

  - (void) setValueAndUpdateDisplay:(NSString*)theValue
  {
    self.value = theValue;
   [self setNeedsDisplay:YES];
  }

...but that sucks, too.

There gotta be a better way!
How do you deal with this?

cheers,
Torsten
