I'd suggest looking at the AirDrop sample code to learn how to add support to an app. Unfortunately the 4S does not support AirDrop (see this kb for more details)
Can I sent file via Air Drop from my app?
문제
I have two iPhone 4S. I want to sent file from one device to another device through my application using Air drop. Actually I want to know can I implement Air drop in my application for file transfer?
