You are, as the kids say, straight trippin'.
I was mostly asking if iOS had similar functionality, but it appears not.
But no, iPhone doesn't have that functionality.
Also, I thought it relevant to mention here that you can indeed read the post very clearly on the iPhone - but a seeming lack of this feature (Intents) in iOS makes this awkward.
(I'm not sure how they're detecting whether that hook is registered or not, though.)
Even just the ability to suppress the error message would be more or less fine.
But you're mistaken. I browse the web using a web browser. Even on my iPhone.
In my opinion, it's a far more elegant solution than encouraging developers to register pseudo-protocols to use in URLs that also result in very awkward interactions if the app's mobile site tries to redirect to the app and it is not installed. (Then again, this gives users a "choice" (!) of whether to open links or Intents in the mobile app or native app.)
