In Obj-C, the concept of static functions/variables does not exists, 
i.e. it's purely a C concept, you can put it wherever you want, it 
make no difference.

OK, there is in fact a little difference. If you put a static function 
into an implementation block, it's possible to access ivars directy 
even if they are declared private.


@interface Foo : NSObject {
@private
  NSString *ivar;
}
@end

@implementation Foo

static void MyFunction(Foo *aFoo) {
  NSLog(@"%@", aFoo->ivar);
}

@end
