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
