__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

Apple deprecated some methods in the UITableViewDelegate protocol, perhaps you'll be able to find the solution using Apple's code as example.

The relevant code of the protocol is as follows:

- (UITableViewCellAccessoryType)tableView:(UITableView *)tableView
         accessoryTypeForRowWithIndexPath:(NSIndexPath *)indexPath
 __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_NA,__MAC_NA,__IPHONE_2_0,__IPHONE_3_0);

As you can see, Apple uses a macro. Perhaps this is the way to go?

EDIT: As noted on the following link [1] __attribute__((deprecated)) is a GCC construct so this might not work in LLVM. I guess this is the reason Apple uses macros, so some other (or no) deprecation construct will be called when other compilers are used.
