How can I make clickable links like the Twitter and Facebook app?

How to make an expression clickable on iOS?

On Twitter and Facebook, usernames like @ and hashtags like # are clickable, and do something native within the app.

What is the best way to implement something like this? It would be nice if there was a drop in replacement for a UILabel for example.

The TTTAttributedLabel project on github is a drop-in replacement for UILabel that supports embedding links. https://github.com/mattt/TTTAttributedLabel

This looks interesting. Would I be able to do my own handling when a link is clicked? For example, present a modal view controller? – Sheehan Alam Jun 21 '11 at 19:06
I believe you'll have to write and register your own URL handler so that your application can handle the click. You may wish to also take a look at the Three20 project (https://github.com/facebook/three20/) as all of the view linkage is done via app-internal URLs. – smountcastle Jul 12 '11 at 14:53

I'm not sure what Twitter does, but the Facebook app uses a library called Three20 to achieve Rich Text UILabels. They have the ability to be formatted and have in-line hyperlinks. You should specifically look at TTStyledTextLabel.
