问题
Hey guys, I am still continuing to build my iPhone project and I am having trouble with launching the facebook application. First of all, I am assuming every SDK Xcode developer knows that the Facebook application doesn't have the facebook or twitter app in the simulation. Since I have a facebook page and a twitter account about my company, I can't seem to test to launch my facebook page from the facebook application or my twitter page from the twitter application because they are not there in the iOS Simulator. So I was wondering how can I open my facebook and twitter page from the facebook and twitter application if they are not there? I don't want to use a Facebook or Twitter URL, then load it into a UIWebView, I want to open the Facebook and Twitter application to launch after the click of a button in my project, then the project will close and open either Facebook or Twitter application (the ones from the app store), so hopefully someone know how they can help me step by step or if they have a code that knows how to run the facebook or twitter application and sorry if my english is not clear enough, but hopefully you can help me or have a better solution to help solve my problem, thanks

I believe the facebook app listens to URI's like fb://, so I would suggest googling around for that.
