A static variable in Objective C has the same semantics as a static
variable in C: it is one, fixed piece of memory.

Compared to a global, a static (whether in a method or outside of it)
has advantage of being invisible outside of the .{m,c,cpp} file in
which you define it.  It is just a question of visibility.  If it is
defined in a method, that piece of memory is invisible outside of the
method definition.

Instances variables are what you want if you want different data for
multiple instances of the same class.
