FBSDKLog: Cannot use the Facebook app or Safari to authorize, fb**** is not registered as a URL Scheme

Hello, tried to implement Facebook with my app, and I followed the tuto but each time I try to log in from my app to Facebook, I have this message : FBSDKLog: Cannot use the Facebook app or Safari to authorize, fb**** is not registered as a URL Scheme.
I did a lot of research and on Stackoverflow they are always talking about the .plist file, but mine is perfectly completed, so I’m a bit frustrated.

OK… I recreated my app from zero and it worked… Very strange… I did exactly the same thing… (or did I?)

I don’t know what was the problem and I will maybe never know… But who cares… It works ! :smiley:
