I want to add copy and paste to my application but make it available to 2.2.1 devices. How should I proceed?

I saw SDKs and Deployment Targets.

If I understand correctly, I set the base SDK to 3.0 in order to be able to compile with 3.0 API (copy & paste), but I set the target for 2.2.1 to make the application available on 2.2.1 devices. In my code, I have to check every time I need to use a 3.0 API, right? Is there an example of code for testing if an object respond to a specific message? If a specific kind of class exists?
