How to view source code?

I noticed that, as contrary to android, you can’t view source code in iPhone as easily, for example how can I view it for this one?: view-source:https://www.facebook.com/stories/113464463189285/UzpfSVNDOjE5NDkzMjM3Nzg3NTI5OTM=/?view_single=1&source=shared_permalink&mibextid=W9rl1R it’s a Facebook link, and obviously you can’t open it without being redirected to the Facebook app, I would really appreciate any help.
