The Doc states:
You should therefore also set outlet variables to nil in dealloc:
- (void)dealloc {
// release outlets and set outlet variables to nil
[anOutlet release], anOutlet = nil;
[super dealloc];
}
why not just use
[self setAnOutlet = nil];
or
self.anOutlet = nil;
Any danger in this? (except a bad implementation of setAnOutlet:)
Any of the standard arguments about not calling setters in dealloc and
init would apply. For example, if you were subclassed, and your
subclass had an override of one of your setters, and you called it
from dealloc you'd be calling one of their methods after they'd called
[super dealloc]. Or, you might later implement side-effects for one of
your setters not thinking about the called-from-dealloc-case and
introduce a subtle bug into your own code.
