To answer your actual question, you might write:

- (void)function2:(NSNumber **)value
{
  *value = [NSNumber numberWithBool:YES];
}

Careful about that - if value is NULL, then that will cause a crash. That's why you have to check to make sure value is not NULL first.

A crash might be better than failing silently in some cases. It's a judgement call, obviously, and certainly something to think about.

Kind regards,

Alastair.
