URLPreview

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.

Requirements

Swift 5 & Xcode 10.2
This library depends on Kanna

Usage

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!")
}

Swift 3 compatibility

Hey, I'd love to see this lib available in Swift 3 so I can implement it in my project.

Thanks 😄

Depreciation

'sendAsynchronousRequest(_:queue:completionHandler:)' was deprecated in iOS 9.0: Use [NSURLSession dataTaskWithRequest:completionHandler:] (see NSURLSession.h

Could you please update your code since this is deprecated for a while now? I have tried it my own, but couldn't get it running...

Errors like that slow down the building process in big Xcode projects.

Question: Desktop User Agent

https://github.com/itsmeichigo/URLPreview/blob/master/Source/NSURL%2BURLPreview.swift#L21
Just curious if there was a specific reason you use a desktop user agent? Do some sites not return the description or image with a standard mobile user agent?
