How to add button to follow application owner's Twitter account from iphone application?

I'm developing an application in which I need to include an option "Share on Twitter " click upon which the application's itunes address is automatically twitted to 开发者_JS百科the user's Twitter account(ofcourse I'm accepting user's id and password). I was able to do that.

Now I want to add a button "Follow" click upon which will enable user to follow the application owner's twitter account automatically.

Anybody having idea how to accomplish this? Thanx in advance.

You need to call the friendships/create method with the ID or username of the person you want to follow. The authentication etc should be the same as you're using to update their status.
