Except that there's a long-standing rule that we shouldn't use leading
underscores for either member variable names or private method names
because names beginning with underscore are reserved for Apple's own
use (even member variable names, IIRC). So if you're going to use a
prefix, it's probably best to pick something like "m" (for "member").
But in general I think it's better not to prefix the names of member
variables, and then in your initialisers, to use a different name for
the argument.
Kind regards,
