Some features don't work as you mentioned

Here is the string I used:

> `This is __rad__ and *this* is another ~~guy~~ \n # Header 1 [Text] (http://google.com 'alt text') urls`

Then I passed it to my label's attributedText like this:
        `self.label.attributedText = string`

The header, the link doesn't work at all. Any idea?
