How to make an expression clickable on iOS?

I am writing a Twitter type client. I want stuff like @ and # clickable. When I click on it, I want it to do some sort of IBAction. I found this for OSX:

This is along the lines of what I want to accomplish. Anything for iOS that is of this caliber?

The best dropin solution I've found was this: https://github.com/SebastienThiebaud/STTweetLabel Clean and simple.

You can make any properly formatted URLs appear as blue underlined active links in a UITextView with the following code (in say viewDidLoad)

self.myTextView.editable = NO;
self.myTextView.dataDetectorTypes = UIDataDetectorTypeLink;

Search for "Technical Q&A QA1495" in Xcode's Documentation and API Reference.

Just off the top of my head, I guess you could achieve it by using a UIWebView to display the content (which you have linkified, as per the "2: Finding The Interesting Parts" part of the blog post).

If you then prefix the hashtag links with a custom url scheme, like myappopenshashtags://, and register that url scheme for your app, you should be able to open your hashtags in whatever way you please.
