I followed the setup instructions in the NativeBase Docs and ran rnpm link. I am getting this error: Unrecognized font family ionicons
rnpm link
also checked by Xco
native-base has 'react-native-vector-icons' as dependency but if you are using react-native <=0.59.10 then you have link.
Just simple command :
react-native link react-native-vector-icons
