Re: How do I disable this warning: "local declaration of 'varname' hides instance variable"

For years, I've been doing this:

- (void)setController:(id)_controller
{
  if (!_controller)
  {
    return;
  }
  controller = [_controller retain];
}



It has always irked me having to work around namespace conflicts
between method args and instance variables.

So, today I decided to try this for my next project...

- (void)setController:(id)controller
{
  if (!controller)
  {
    return;
  }
  self->controller = [controller retain];
}



I works fine.  But does not fix the warning itself.




So, the question stands.... How do I suppress the warning.
