Answer 1

That is an issue on your end. The method showFromViewController was introduced in v4.6 of the Facebook iOS SDK but as you are using v4.1 this method does not exist in the SDK.

You should upgrade to the most recent version of the Facebook SDK for iOS (v4.8 as of now) and then it should work fine.
