I didn't ask for advice.

I asked a simple question.

And it still stands.

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.


You suppress the warning by fixing the problem it's warning you about. Yes, it's just that simple.

For example, the above could be rewritten as:

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