Facebook and Twitter API help for Iphone SDK

Im trying to implement Facebook and twitter into my app, anyone link a place with a good step by step for each.
I have tried several on various sites and youtube, and all have made my app crash. Any help would be appreciated thanks.
One place to start might be using ShareKit:

That bundles together a lot of social platform updates in something easy to integrate. I think you can customize it beyond what is there.

For twitter I use cocoa built in
twitter.h
for iOS apps.
Definetely:
