Disabling a specific warning in a specific line in Xcode

Question

I'm writing an iPhone app against the Base 4.0 SDK, but I'm targeting OS 3.1.3 so OS 3 users can use the app.

I call:

[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES];

which is deprecated in iOS 4.0. I'm aware of this, and have measures in place to call the newer "withAnimation" version if we are running under iOS 4.0 or greater.

However, I'm getting a warning that I'm calling a deprecated SDK.

I'd like to disable this specific warning in this specific place. I want all other warnings (including the same deprecated warning in other locations)

Can this be accomplished in Xcode?

For CLANG, this works:

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
  // Here I like to leave a comment to my future self to explain why I need this deprecated call
  NSString *myUDID = [[UIDevice currentDevice] uniqueIdentifier];
#pragma clang diagnostic pop

You can use it inside a method, which allows you to be very specific about the line that causes the warning you want to have ignored.
