Facebook login iOS (native)

Hi,

We are having some problems with the Facebook authentication. Is there somebody who has succesfully realized the login with the native Facebook app?

If so, i hope you can help us out! Thank you in advanced.

I was dealing with the same issue! Luckily I was able to get it all sorted out. Try this :

  1. Update your Facebook plugin using [cordova-plugin-facebook4] (https://github.com/jamielob/cordova-plugin-facebook4). This is a branch off of [the main Cordova FB plugin] (https://github.com/Wizcorp/phonegap-facebook-plugin/) except he has updated the plugin’s FaceBook SDK to the latest version fixing the broken simlink issue.
  2. The ionic @dwieeb just merged my pull request for the ionic-package-hooks repository, which consists of ionic supported cordova hooks. Follow the READM and you should be set.

Bonus : If you’re still having issues, try opening your xcode project in <PROJECTNAME>/platforms/ios and then [disable Bitcode in your build settings] (http://stackoverflow.com/questions/30848208/new-warnings-in-ios9).

Thanks alot! I hope this will help in our case. When we have time to work on it again, i’ll let you know!

After many, many, many hours struggling with this facebook native login, I did find out that the only solution to work properly was that cordova-plugin-facebook4 that @carsondrake mentionned.

It removes every problems you might have when trying to build your app because of the android support library v4 VS v13.
