Well, you could do NSStringFromClass([self class]) but that gives the name of
the object's dynamic class, which is not necessarily the same as the class in
which the method is implemented.

Are you aware of the __func__ (or __PRETTY_FUNCTION__) compiler-defined
variable? It is a C string whose content is "-[MyClass myMethod]". (In a
function, it will be the function name rather than the method name.)
So, you could do:
NSLog(@"%s", __func__);

It almost certainly can be turned off. Usually, the warning line from the
compiler explains which warning option enabled the particular warning and you
can turn it off by insert "no" in a compiler option. However: 1) it's a
valuable warning, and 2) you're already using a format string to construct
fooText. Why not just put that format string into the NSLog() call and
eliminate the fooText temporary variable?
