How do I can integrate Facebook to my own app?

I have an app. I want to integrate Facebook to this. I want to make it because I have a program, which count numbers. I want enable the user to send its counted number to his/her user feed on Facebook. I have read the facebook's page for developers about the sdk, and about the imports, but I don't know for example, how I can make my program, that the user need to press a button, and then if he want to connect to FB , he will can. I only read about how I can build all of my program "over" FB . And 开发者_运维百科I don't know how I can enable the user, to post its number to fb if he press a button, but I only want to show this button, if the user connected to fb. Could you please give me any tutorials, helps, and advices please? Or example codes? Thank in advance!
