I have an task to make ours company application more voice controlled. To do this I would like to integrate it with Siri the same way like Facebook app integrates (Look at the screens). How can I accomplish this. I was looking for some frameworks on Apple side that can let me do it but I can't find any suitable framework to do it. I know this must be something like service extension or app extension that is starting with iOS (not with my application) because Siri knows that the Facebook is integrating with it even when the Facebook app is turned off. Take a look at those screens to see what kind of integration I'm talking about. This screens can be opened when I say to Siri: "What can You do":
As the comment mentioned, Apple decided to partner with certain companies and integrate these features into the OS and it's impossible for you to do so yourself. If you go to the Settings menu, you'll notice you can link your Facebook/Twitter/Flickr/Vimeo account even if you don't have the corresponding apps installed.
