__attribute__ ((deprecated)) does not work on objective-c protocol methods?

Question

I need to deprecate a single method in objective-c protocol. On normal class/instance methods I add __attribute__ ((deprecated)); after declaration.

It seem

Answer 1

Well, I just realised, that even Apple use __attribute__((deprecated)) at the end. And it does not work either. If I use any deprecated delegate method, e.g.

- (UITableViewCellAccessoryType)tableView:(UITableView *)tableView
     accessoryTypeForRowWithIndexPath:(NSIndexPath *)indexPath

there is no warning.

So it seems like a candidate for radar.
