When I added fbsdk in my project, I got errors like -
Warning: Native component for \"RCTFBLikeView\" does not exist 2016-06-21 22:27:38.898 [warn][
I was struggling with this recently and what I found to work is that, after running react-native install react-native-fbsdk you still need to run react-native link react-native-fbsdk.
The libRCTFBSDK.a will then appear under Link Binary with Libraries in Xcode but (I think) needs to be removed and then re-added by clicking the - and + buttons at the bottom.
