facebook redirect_uri set to ios URL Scheme

Question

I'm starting to investigate how to work with Facebook programmatically.

I've set URL scheme in my app, so that I could open it from browser using "myappopenup://".

Then I created an app in Facebook. Copied an AppId and tried to make like this:

let url = NSURL(string: "https://www.facebook.com/dialog/oauth?client_id={MY_APP_ID_WAS_HERE}&redirect_uri=myappopenup://fbcallback")
UIApplication.sharedApplication().openURL(url!)

After running this code, simulator opened safari (I've tried with SFSafariViewController first). but everything I saw was:

So, I'd like to know: Is it possible to redirect from the Facebook oauth to my app?

Answer 1

Yes it is possible. Here's the necessary redirect_uri:

  https://graph.facebook.com/oauth/authorize
  ?response_type=token
  &client_id='+'1247676148624015
  &redirect_uri=fb1247676148624015://authorize

Make sure your facebook app is set up:

And make sure your custom URL scheme is set up:

Disappointing comment above -- likely misled many people. This stuff is not well-documented at all, though.

Answer 2

I contacted Facebook support and they confirmed that it's not supported:

Thanks for getting in touch. We'll make the messaging more clear on this, but we do not support custom URI schemes as valid redirect URIs. To perform login in a native app without opening the browser, please use the official SDKs (is https://github.com/xamarin/FacebookComponents what you're looking for?).

They responded in less that 12 hours, which at least was impressive.

Answer 3

I managed to make Alex Paterson solution work here. I had to add the redirect_uri URL on Facebook Login settings too. On section Valid OAuth redirect URIs I've added the callback URL like this:

https://graph.facebook.com/oauth/authorize?
response_type=token&
client_id=12345678910&
redirect_uri=fb12345678910://authorize
