pre-iOS 4 devices delegate protocol

Question

Can I add the UIBannerViewDelegate protocol to my UIViewController subclass while remaining compatible with pre-iOS 4 devices?

This is NOT a duplicate, the question is specifically related to the delegate protocol.

Edit your previous question to clarify it. Don't create a new one. [Are Apps using iAd compatible with older iOS](http://stackoverflow.com/questions/3128457/are-apps-using-iad-compatible-with-older-ios) — Michael Petrotta, Jun 27 '10 at 19:53

I’d try something like:

#ifdef __IPHONE_4_0

@interface MYViewController <UIBannerViewDelegate, …>

#else

@interface MYViewController < … >

#endif

Remember to #include <TargetConditionals.h>;.

Edit: this question duped Are Apps using iAd compatible with older iOS which has a more complete answer.
