While working through "Beginning iPhone 3 Development" I've seen the
following a lot, and it seems like a general Cocoa issue.
In -viewDidUnload methods the code has the form:
self.foo = nil;
Whereas in -dealloc methods the code has the form:
[foo release];
Both methods seem to me to do the same thing (releasing foo), but I
presume the first one would trigger any KVO observers where as the
second wouldn't. Is that why the simple "release" is used instead of a
setter in the dealloc methods, to avoid KVO? Is this a general Cocoa
pattern?
Thanks,
Todd
