I am using Xcode 6.2, Facebook-iOS-SDK 4.0. I used to have working code with Facebook-iOS-SDK 3.20.0.But, now I am getting compile-time error FacebookSDK.h not found. I am using pod to install sdk. Can someone give me any pointers why this is happening?
The SDK (v 4.0) is no longer one framework named "FacebookSDK", but rather a few different packages with a naming convention of "FBSDKTypeKit", where types are different things like Core and Login. This means the name of the header files have also changed, so that's why your project can no longer find FacebookSDK.h (as it's now FBSDKCoreKit.h).
