This isn't a question of difference; it's about usage.
In many cases, a class has both a "generator" class method (one that
returns an initialized instance of the class), as well as an instance
method that initializes an existing instance, and the two are
otherwise identical in usage. For example, NSString. I can call:
NSString *stuff = [NSString stringWithString:otherStuff];
or
NSString *stuff = [[NSString alloc] initWithString:otherStuff];
The question is this: is there an advantage to one over the other, and
why? If so, is this something I should determine on a case by case
basis? Is +stringWithString: just a shortcut for +alloc and -
initWithString:?
