You can also use more readable define DEPRECATED_ATTRIBUTE

It defined in usr/include/AvailabilityMacros.h:

#define DEPRECATED_ATTRIBUTE        __attribute__((deprecated))
#define DEPRECATED_MSG_ATTRIBUTE(msg) __attribute((deprecated((msg))))

Objective-C methods example:

@interface MyClass : NSObject { ... }
-(void)foo:(id)x DEPRECATED_ATTRIBUTE;

// If you want to specify deprecated message:
-(void)bar:(id)x DEPRECATED_MSG_ATTRIBUTE("Use baz: method instead.");
...
@end

You can also mark the whole class as deprecated:

DEPRECATED_ATTRIBUTE
@interface DeprecatedClass : NSObject { ... }
...
@end
