How to programmatically "like" a Facebook page within an iOS app?

I want to add code to my iOS app which prompts users to "like" my app's Facebook page after they use the program X number of times. However I want to keep it as simple as possible for the 开发者_JAVA百科user. What are the best practices for programmatically "liking" a page? Right now, I have a link to my Facebook page in the "Help" screen, but I want to make it more visible to the user and try to get more "fans."

There's no API to actually create a Like connection.

No, there isn't really way to like anything without user's click. It's because of malicious applications/sites
