Method 2: Otherwise use the following pair, where the return value is autoreleased in the scope of the caller, which is more correct. This is also more (but not fully) thread-safe as the returned value is autoreleased in the calling thread.

- (NSString *) title {
return [[title retain] autorelease];
}

Sorry, perhaps I am just plain dumb, but in what situation this would bring any advantage to

-(NSString*)title { return title; }

? I just can't see it: we just increment the r.c. (presumably to two, since -- being in an instance variable -- it would be retained already), to be decremented back in some future... regardless in what thread this is done, what is it good for?
