No, you do need to release it. You should release the ivars for any
retain or copy-type properties in your -dealloc implementation. Is
your property was just an assign property, then you would not need to
release it in -dealloc.
Also - a common mistake when using properties is to set the ivar, but
not use the property setter.
This: name = [NSString string];
is very different from this: self.name = [NSString string];
as the latter is equivalent to: [self setName:[NSString string]];

Thanks again both of you.
assuming that I do self.name = [NSString string] and since it the
NSString helper message, I shouldn't have to release that in my
dealloc implementation.
Or am I understanding this incorrectly.

However, doing this will yield a memory leak:

You're right that it will leak in that case but you've given the
wrong
reason as to why. Memory management rules are covered by Apple's
documentation.

Thanks for your reply, Chris.
I suggest that the code quoted above will yield a memory leak
because the
NSString instance allocated will have a retain count of two after the
setName: message has be sent to self. To correct this error, I
suggest that
the code should read:
self.name = [[[NSString alloc] init] autorelease];
Under the heading of "Setter Semantics"
of <http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/Articles/chapter_5_section_3.html#//apple_ref/doc/uid/TP30001163-CH17-SW2
>,
I can see that Apple's documentation clearly states that the
implementation
of a property declared with a retain attribute will send a retain
message to
the value given in the right hand side of the assignment.
I'm confused as to why else the memory would be leaking? Can you
please
identify my error?
Thanks,
Kiel
