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.

• Swift 5 & Xcode 10.2
• This library depends on Kanna

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!")
}
