How to check for API availability in Xcode 9

Question

I'm using he UserNotification framework that is available only in iOS 10. I am declaring a method that uses this framework and so far, I have been doing the check for the availability as follows:

@interface MyService : NSObject
 #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 100000
    -(BOOL)handleWillPresentNotification:(UNNotificationContent *)notificationContent;
#endif
@end

XCode 9 beta was just release and with this code I get a warning

'UNNotificationContent' is partial: introduced in iOS 10.0 Annotate 'handleWillPresentNotification:withCompletionHandler:' with an availability attribute to silence

The question is how do I annotate this in Objective C code the entire method? I know that Xcode 9 introduced the

if (@available(iOS 10, *)) {
    // iOS 10 ObjC code
}

but how do I wrap the entire method (including its signature) in it?

cheers

Answer 1

to answer my own question: I need to mark the method using the NS_AVAILABLE_IOS macro as follows:

-(BOOL)handleWillPresentNotification:(UNNotificationContent *)notificationContent NS_AVAILABLE_IOS(10_0);
