How to implement Facebook to my app

I am used Facebook for my application where I have to post comment on wallpaper. But now I have to modify that application. 开发者_高级运维I want page after user login it will give option like

1. post to wall
2. retrieve friends
3. logout

Can we implement this page after login instead of direct opening the page of post wall.

If yes then provide me some code with brief details. Even your previous code help me lot to solve my previous problem

I am not sure if I correctly understand your question, but if you are looking for an easy way to post comments and images to a wall or also to retrieve friends etc ... go check out BMSocialShare - currently better use the dev branch though! In case you want to share to many other platforms as well try ShareKit.
