Post Twitter message from iPhone app with OAuth

How can I post a message on Twitter from my app开发者_StackOverflow社区 using OAuth authentication?

I'd like to post an invariable message with a variable link...

How can I do this?

Any source? Any tutorials?

Thanks a lot!

Use an OAuth library such as:

There are various tutorials out there like:

It can be tricky, especially since twitter has changed since some of the popular iPhone implementations were written, but this will give you a place to start.
