An NSURL extension for showing preview info of webpages.

You may want to use it if you want to mimick Facebook app's behavior when you post a link on your status.

This library depends on Kanna - a brilliant library for parsing HTML/XML on Swift.

Pretty simple, all you need is a block:

if let url = NSURL(string: urlTextField.text!) { url.fetchPageInfo({ (title, description, previewImage) -> Void in // do whatever you want here }, failure: { (errorMessage) -> Void in print(errorMessage) }) } else { print("Invalid URL!") }
